Any one else hear of these? They are brand new by Luxim, going to be released at the International Trade Show in Germany in April. Check them out, sweet possibilities.

Wow, excellent find, those are AWESOME!

He said in the video that the spectrum was similar to the sun, because the bulb gets 6000 degrees inside, the temperature of the surface of the sun :-) These are amazing bulbs.

The 6000K temperature mentioned was NOT degrees as in farenheit or celsius, it is 6000K (K= Kelvin) which is a color spectrum only. 6000K (blue spectrum) represents daylight color meaning that these bulbs should ONLY be used for vegging, the 'red' spectrum is (appx. 2200K-3000K) for flowering.

If you examine even a simple package of CFL bulbs they will be in either the 6000K range or the 2700-3000K range, CFLs are not produced as low as the 2200K range like HPS bulbs are. CFL bulbs that are in the 6000K range are "Daylight" or "Bright White", CFL bulbs in the 2700-3000K range are marked "Soft White" or "Cool White". Now I only mention CFL to you all because we can walk into ANY store and pick up a package and have a look at them. ALL of your HID bulbs are marked/sold in a similar fashion, just read all the specifications very carefully on any website you visit dealing with bulbs.

Listen again to the video where he says "the inside of the bulb will be 6000 Kelvin in temperature" 6000K is a color spectrum measurement and NOT an actual temp even though he does compare it to the surface of the sun.

Also, he states that the new Luxim bulb puts out 140 lumens per watt, so does my 400watt HPS! My 400watt HPS Hortilux is rated @ 55,000 lumens or appx 137.5 lumens per watt. So what's all the fuss about now?

BTW, the 400 watt HID unit in the demo had not warmed up yet, I think we can all agree that when street lights turn on they take a minute or so to warm up. ahhhhhhh the magic of the camera and not being there made that a real dog and pony show for anyone wanting to be taken in by new ideas in lighting.

I hope this $ave$ you all thousand$ of dollar$ by $ticking with standard HID bulbs, I know I won't be buying some CEO's bag of trick$.

papa told me "son, believe none of what you hear & only half of what you see."
I didn't see shit in that demo of theirs that'd prove anything.

The kelvin (symbol: K) is a unit increment of temperature and is one of the seven SI base units. The Kelvin scale is a thermodynamic (absolute) temperature scale where absolute zero, the theoretical absence of all thermal energy, is zero (0 K).

6000k is 6000 degrees above absolute freezing. It also is used to measure the light spectrum. The surface of the sun is almost 6000k in heat, 5500 somthin. The sun is cooler at it's surface then it is in the outer edges, and hotter stil at the core. "At the Sun’s center, the temperature is 15.6 million degrees C (28.1 million degrees F), and the density is more than 13 times that of solid lead. This is hot and dense enough to make the nuclei fuse together. Outside the solar core, where the overlying weight and compression are less, the gas is cooler and thinner, and nuclear fusion cannot occur.
"

MOST cfls you come across will not list actual spectrum, rather, daylight, general purpose, or soft. Some do though.

This lamp is considered an LED, so very little heat, and spectrum will be able to be changed just like an LED. Give it some time, and they will get cheap.
Until now, HPS was the most efficient light source we have for the general population, producing more light per watt then anything, until now.

"Apparently, the company has created a micro-sized bulb that uses 250 watts of power, but outperforms a 400 watt HID. Gas inside the tiny bulb is electrified by a component called a puck, which heats the gas into plasma and produces light, allowing a sizable chunk of energy to become light rather than heat—thus the ultra-bright performance. Inside the mint-sized bulb the gas reaches 6000-degrees Kelvin—or about the surface temperature of the Sun—producing 140 lumens per watt, or roughly ten times that of a standard light bulb."

I have yet to see a 400 watt anything that will put out more then 120 lumens a watt, with a brand new ballast and expensive bulb that lasts 8 months. They may be out there, I just have not read them. These new bulbs will last like LEDS, with 1/2 the heat output or maybe even less.

I think they are pushing these into projection TV's and using the 3 color projection like we are used too. Won't be long until we have all spectrums available, people just have to buy a lot of projection TV's :-)

Of course, at 2-3k a pop, you can buy a LOT of 1000w hps's :-)

My point here is that this is hardly hype. This technology is what is next in line for us. High powered LEDs. Who could ask for anything more!!!! Won't it be nice to use fans for just circulation and the carbon filter. A minimal heat signature may just be worth a few Thousand to the right growers :-)

[Racefan]

I'll be impressed when the average grower can afford them. Until then they are just a new product that only the governement and rich can afford. When the average grower who makes minimum wage can afford these I'll jump on the bandwagon.

[Boss]

No doubt :-)

Just watch out the next time the local city wants to replace the street lights...

[Brett2theMax]

How much are they going for? They are brand new and haven't even been released yet so I'm sure price will go down. Did they mention price in the video? I must not have been paying attention to that part. I went looking for cost and couldn't find it, Luxim's website says it is going to be officially released at the German International Trade Show in mid April.

What I really liked about them was the fact that they are so small, a small computer fan overkill for cooling them. I hope they can figure out how to change spectrum on them too, I fell like it would be difficult because of the way they are creating light by making a gas into a plasma. I'm assume different gas's turn to different spectrum plasma though, really have no idea what I'm talking about but I like to think that is possible.

[Aqua Lab Tech]

Here is another nice brand of LED grow lights:

LED Grow Lights - Plant Grow Lights


Aqua Lab Tech

[Boss]

That's a very nice lamp. However, at 6 times the price of a 400w hps it will take 15 years to pay for the difference in energy cost, which is probably 7 years longer then the bulbs last. We are getting there, a bit at a time. Those are the brightest LEDS I have ever seen though, other then the one above. It's nice to see a true LED grow light.

Soon we will have grow rooms with nothing but LED lamps and a few odor eater CFL's and a single fan for exhaust and air movement. A room that used to use thousands of watts will now use 60% less energy with the same or better results. Still a bit pricey for me though :-)

[dava04]

I agree with Boss about the tempreatures, that is what the man said, the middle of the bulb has plasma and it heats up to 6000K, kelvin being the technical mesaurement for temp.

These however aren't LEDs, listen again the man says there no electrodes, and if you look there is no silicon in the bulb. It is a gas discharge lamp, hence he was talking about the plasma heating up to 6000K, typically anything over 60 deg C is very bad for LEDs, these are not LEDs.

Also I don't think they would be any good for growing, wavelength is what your all searching for red and blue, so surely anything that has a focused wavelength and a high output is better.
That white light is white in the human simulated sense, it combines all the colours to make a white light, however it contains nothing outside of that, so for growing thats wasted light, while remember the sun shoots out everything from gamma waves to radio waves, in huge doses.

So those light look scarily good, but their intended use right now is for street lighting, and they will be expensive, typically an LED street light goes for between $500 and $1500 dollors a pop, and thats when your buying more than 50 aleast.

Its going to take a long time before you see one of them with a dedicated red spectrum and even longer for blue (blue being the hardest colour to make)

[Medical Marijuana]

It is critical to also equate the UV from sunlight into an LED - it is the factor in maximising potency. An elaboration on the phytochemical process that makes THC

[dava04]

Really, then that could be the major limiting factor then as LED's give very little UV light, unless you specifically buy a UV LED.

This is why they use LED's for lighting works of art as they doesn't bleach the colour of the painting.

How does the plant use the UV?

Suppose you could add an extra UV light!

The UV activates the psychactivity of the THC.

When the resin spheres are separated from the dried plant material by electrostatic attraction and placed on a microscope slide illuminated with a 100W incandescent bulb, they appear very dark when observed through a 300X microscope. Since orange, red, and infrared are the component wavelengths of incandescent light, and since the absorption of light makes an object dark or opaque to the frequency of the incoming wave, one can conclude that these wavelengths are probably not directly involved in energizing the cannabinoid pathway.

However, the resin sphere is transparent to ultraviolet radiation.

The author found through trial and error that only one glandular
trichome exhibits the phytochemical process that will produce the amount of THC associated with pain relief, appetite stimulation and anti-nausea; euphoria and hallucinations are side-effects, however. This trichome is triggered into growth by either of the two ways that the floral bract is turned into fruit.

Of all the ways that optics are involved in the phytochemical production of THC, the most interesting has to be how the head cells and cannabinoid molecules are tremendously magnified by the resin sphere. These and other facts are curiously absent from the literature. The footnotes update the literature to include electrostatic separation of the resin sphere from the dried plant material and marijuana parthenocarpy.


(1) "For all spheres, a ray drawn perpendicular to the sphere's surface will intersect the center of the sphere, no matter what spot on the surface is picked, and the magnifying power(a) of a glass sphere is greater the smaller its size. A sphere of glass can also bring light that is heading to a focus behind it to a point within it, with freedom from two aberrations, spherial aberration and coma, but not from chromatic aberration. Chromatic aberration results when different wavelengths are focused on different planes and is the most difficult of the aberrations to correct. The human eye lens also exhibits chromatic aberration, but a yellow pigment(b) called the macula lutea in the fovea, an area at the rear of the eyeball, corrects this problem by the way it absorbs blue light."

(a)"The formula to calculate the magnifying power of a sphere is l=333/d, where l is the magnifying power and d is the diameter of the sphere expressed in mm."

(b)Interestingly, the resin exuded by drug-type flowering female marijuana plants has a yellow tint. Could this pigment work to correct chromatic aberration in the resin sphere like the macula lutea does in the fovea for the eyeball?

(2) Quoting from the Mahlberg and Kim study of hemp(a) "THC accumulated in abundance in the secretory cavity where it was associated with the following: cell walls, surface feature of secretory vesicles, fibrillar material released from disc cell wall, and cuticle. It was not associated with the content of the secretory vesicles."

The resin spheres contain the THC. It is not contained in the leaf or floral bract. After the resin spheres are dissolved in solvent or dislodged by electrostatic attraction, and a microscopic examination of the leaf or floral bract has revealed that only the glandular trichomes' stalks remain, no effect will be felt after smoking the dried plant material from which the resin spheres have been removed.

(3) The electrostatic collection of the resin spheres from dried marijuana plants with plenty of ripe seeds has been for hundreds of years the method indigenous people of North Africa and Lebanon have used to make hashish. Obtain a round metal can 8" or so in diameter x 3" or so in depth (the kind that cookies come in) with a smooth lid. Obtain 2 ounces of dried marijuana with plenty of ripe seeds in the tops. To remove the seeds and stems, sift the marijuana tops through a 10-hole-to-the-inch wire kitchen strainer into the can. Close the can with the lid and vigorously shake the closed can three or four times. This gives the resin spheres an excess negative charge. Let the can sit for a moment and then remove the lid. Opposites attract. The negative-charged resin spheres have been attracted to the metal surface of the can and lid which has a positive charge. Take a matchbook cover or credit card and draw the edge across the surface of the lid. Note the collected powder. Observed under 300X magnification, the collected powder from this "shake" is composed of resin spheres with an occasional non-glandular trichome. As the marijuana is shaken again and again, and more of the yellow resin spheres are removed from the plant material, the collected powder gradually becomes green-colored as the number of non-glandular trichomes increases in the collected powder. The greener the powder, the less the effect.

(4) "Cannabinoids represent a dimer consisting of a terpene and a phenol component. Cannabigerol (CBG) is the first component of the pathway. It undergoes chemical change to form either cannabichromene (CBC), or cannabidiol (CBD). Delta 9-tetrahydrocannabinol (THC) is derived from CBD."

(5) "Pate (1983) indicated that in areas of high ultraviolet radiation exposure, the UVB (280-320 nm) absorption properties of THC may have conferred an evolutionary advantage to Cannabis capable of greater production of this compound from biogenetic precursor CBD. The extent to which this production is also influenced by environmental UVB has also been experimentally determined by Lydon et al. (1987)."

The writer's own experience allow for a more specific conclusion: If the UVB photon is missing from the light stream(a), or the intensity as expressed in µW/cm2 falls below a certain level(b), the phytochemical process will not be completely energized with only UVA photons which are more penetrating but less energetic, and the harvested resin spheres will have mostly precursor compounds and not fully realized THC(c).

(a)Examples of an environment where the UVB photon would be missing from the light stream include all indoor cultivation illuminated by HID bulbs and in glass or corrugated fiberglass covered greenhouses.

(b)"The maximum UVB irradiance near the equator (solar elevation angle less than 25 deg.) under clear, sunny skies is about 250 µW/cm2. It was observed that the daily solar UVB in Riyadh, Saudi Arabia (N24.4Lat.) decreased from September to December by about 40% (Hannan et al. 1984). The further a person is from the tropics, the less UVB radiation there is: the average annual exposure of a person living in Hawaii is approximately four times that of someone living in northern Europe." Below are some UVB readings taken in Hoyleton, Illinois, on a clear sunny day in June by David Krughoff as reported in Reptile Lighting 2000.

7am: 12 microwatts/cm2
8am: 74 microwatts/cm2
9am: 142 microwatts/cm2
10am: 192 microwatts/cm2
11am: 233 microwatts/cm2
12pm: 256 microwatts/cm2
1pm: 269 microwatts/cm2
2pm: 262 microwatts/cm2
3pm: 239 microwatts/cm2
4pm: 187 microwatts/cm2
5pm: 131 microwatts/cm2
6pm: 61 microwatts/cm2

(c)Cannabinoid pathway: Anywhere in this pathway UVB does a better job than UVA in energizing a phytochemical reaction that will produce more fully realized THC because "all cannabinolic compounds show an absorption maximum between 270 and 280 nm in the ultraviolet region."

(6) Capitate-stalked glandular trichome.

(7) #1: The ovum has been fertilized and there is a seed developing: In the areas of the Northern Hemisphere where indigenous people have grown heterozygous drug-type marijuana for hundreds of years, pollination is used to trigger the growth of the capitate-stalked glandular trichome on the floral bract and concomitant leaves of the flowering females before the autumnal equinox(a) so the majority of seeds will be ripe(b) before November.

(7) #2: The floral bract has become parthenocarpic: Parthenocarpic fruits develop without fertilization and have no seeds. Except for transmutation and turning lead into gold, there has been more nonsense written about seedless marijuana than on any other subject. In marijuana parthenocarpy, the floral bract (the fruit) enlarges in size as though there were a seed growing inside, and the capitate-stalked glandular trichome is triggered into growth on the floral bract and concomitant leaves. "Most popular supermarket tomatoes are parthenocarpic which was induced artificially by the application of dilute hormone sprays (such as auxins) to the flowers." In a trial, marijuana parthenocarpy was not induced by the application of the spray used on tomatoes. Only the photoperiod(c) will trigger parthenocarpy in flowering female marijuana plants. Marijuana parthenocarpy occurring before the autumnal equinox is considered by the author to be "long-day" and marijuana parthenocarpy occurring after the autumnal equinox to be "short-day".

The longest photoperiod that will trigger parthenocarpy in unfertilized flowering homozygous(d) Indica female marijuana plants is 13:00 hours, give or take 15 minutes. This effect can be obtained in the month of August at N35Lat, and because the capitate-stalked glandular trichomes received plenty of UVB during this month at this latitude, the harvested resin spheres had fully realized THC. Rating: euphoria and hallucinations, major appetite boost and pain relief, deep dreamless sleep. These plants seldom grow taller than four feet but potency makes up for the reduced harvest.

The gene pool is heterozygous if a flowering female marijuana plant is not parthenocarpic by the end of the first week in September in the Northern Hemisphere. If this is the case, pollination is used instead of parthenocarpy to trigger the growth of the capitate-stalked glandular trichome before the autumnal equinox to obtain as much fully realized THC as possible in the harvested resin spheres by the time the majority of the seeds are ripe.

The longest photoperiod that will trigger parthenocarpy in unfertilized flowering heterozygous female marijuana plants is 11:00 hours, give or take 15 minutes: This effect can be obtained in the month of November at N35Lat. Because of the low intensity of UVB radiation at this latitude at sea level during November, the harvested resin spheres evidenced only slightly more THC than precursor compounds. Rating: mild to medium euphoria, appetite boost and pain relief, good snooze.

Thai marijuana falls into this 11:00 hour category, and its parthenocarpy is characterized by an inflorescence in which many floral bracts are attached to an elongated meristem. It is these elongated meristems that are harvested to become a THAI STICK. On the other side of the world, Mexican marijuana grown around the same latitudes (Michoacan, Guerrero, Oaxaca) also falls into this short-day parthenocarpic category and the unfertilized marijuana will become "sensimilla" in the 11:00 hour photoperiod which begins in mid-December in that region. The winter sunshine in those latitudes has enough UVB intensity to produce fully realized THC--unlike the winter sunshine at N35Lat.

All unfertilized flowering female marijuana plants will become parthenocarpic in a 9:00 hour photoperiod (15:00 hour dark period): This can be obtained in the month of December at N35Lat. At this latitude in this month there is not even enough UVB in sunlight for precursor vitamin D3 to develop in human skin. The phytochemical process will not produce fully realized THC when UVB falls below a certain level of intensity expressed in µW/cm2. Rating: no effect.

(a)In the Northern Hemisphere above the Tropic of Cancer, the key to all marijuana potency is this: The more days of sunlight the capitate-stalked glandular trichomes' resin spheres accumulate before the autumnal equinox the more fully realized THC.

(b)It is recognized in the indigenous world that drug-type marijuana with a majority of ripe seeds will produce more euphoria, hallucinations, appetite stimulation, pain relief, and sleep aid than with a majority of unripe seeds.

(c)The photoperiodic response is controlled by phytochrome. "Phytochrome is a blue pigment in the leaves and seeds of plants and is found in 2 forms. One form is a blue form(Pfr), which absorbs red light, and the other is a blue-green form(Pr) that absorbs far-red light. Solar energy has 10X more red (660nm) than far-red (730nm) light causing the accumulation of Pfr." The first and last hour of a day's sunlight is mostly red light because of the scattering effect on blue light. "So at the onset of the dark period much of the phytochrome is in the Pfr form. However, Pfr is unstable and returns to phytochrome Pr in the dark." The red light in sunrise returns the Pr to the Pfr form. "Phytochrome Pfr is the active form and controls flowering and germination. It inhibits flowering of short-day plants (the long night period is required for the conversion of Pfr to Pr) and promotes flowering of long day plants."

(d)In Nepal and nearby areas of India where the capitate-stalked glandular trichome is triggered into growth by parthenocarpy rather than by fertilized ovum, great care is taken to make sure that all male marijuana plants are destroyed as soon as they reveal their sex. This is because unfertilized Indica flowering females can have both stigma and anther protruding from the floral bract. In the Indica gene pool, female-produced pollen carries an allele for long-day parthenocarpy, and seeds resulting from this female-produced pollen will produce another generation of female plants that will also exhibit long-day parthenocarpy during flowering. But if pollen from male plants is introduced into this gene pool, the resulting seeds will produce a generation of females that will exhibit short-day parthenocarpy instead. The allele for long-day parthenocarpy in the female-produced pollen is carried into the gene pool by self-pollination and cross-pollination, and perhaps homozygous is used too loosely here to describe the genetic result.

(8) It appears that the resin sphere acts as an UVB receptor and magnifying lens. The latter apparently lets it gather in a lot more photons than would otherwise be possible; because a lens also acts as a prism, the resin sphere may prevent some wavelengths from being focused where the phytochemical processes are taking place because they could interfere with the phytochemical process that makes THC.

The Kelvin temp rating of light refers to the wavelength of the light emmited from carbon when heated to that particular Kelvin temperature. I think it's carbon but it could be something else like hydrogen, but the concept is correct.
