what about "Galaxyhydro 300" ? cheap LED but gives great yields

How so? Most breakdowns appear to be partial ones. As I understand it, the customer has the option of shutting down his/her grow, cleaning up the light, boxing it properly for shipment, sending it back to the manufacturer... and waiting for the repaired product to return.
Or he/she can simply continue using the light while the manufacturer ships the parts to the grower, then swaps the components - which is generally a relatively simple operation - and continues with the grow. If the repair is done during the dark period, the plants never even notice.
Now if you're running half a dozen lights, lol, I don't suppose it really matters (especially since people running larger grows with multiple light sources... ought to have a spare of some sort in the cupboard for emergency use anyway
). But if you are only running a single-light grow... Which option would YOU prefer?Not exactly a helpful tool, IMHO, unless you're setting up area lighting for people to use instead of plants. A lux meter doesn't measure PAR (photosynthetically active radiation), or even gross light amounts. Lux is derived from lumen (luminous flux). A lux is simply one lumen per square meter.
Luminous flux is NOT radiant flux! It's weighted toward the frequencies that our eyeballs perceive as being brighter. And luminous flux is definitely not PAR.
At best, such a device is usable when comparing two light sources where the only difference is power (wattage). For example, a 600-watt HPS will score higher on such a meter than a 400-watt one (at least, assuming the makeup of the bulbs are similar, et cetera). If you have an LED panel running at 300 watts and you drive the same model of panel at a higher wattage, it'll score higher on the lux meter. But your electrical bill, the products specifications sheets, and common sense would tell you the same thing.
It is not helpful - and could easily be a detriment - to use a lux meter to compare different models of LED products. Why? You can take a LED panel, swap out some diodes - thereby changing the spectral output of the thing - to increase luminous flux without having to increase power... and easily end up with a product that is LESS capable of growing plants.
It's output would appear brighter to the Mark I Eyeball, Human, though. I guess if you like reading the Sunday morning newspaper in your growroom, well, this could provide some benefit - to YOU
. Me, I'd rather help the plants and go read my paper under a desk lamp...Increase the GREEN in a LED panel's output, and lux / lumen / luminous flux goes way up. Now... it appears that plants do use *SOME* green light for *SOME* processes - but a spike in green is not going to do much in terms of increasing yield, lol. I doubt you'd even notice the difference. Err... Unless you happen to be looking at a lux meter.
I'm probably horrible at explaining this stuff. For some decent consumer-level education, there's always Wikipedia, lol. See:
Lumen (unit) - Wikipedia
Lux - Wikipedia
Photosynthetically active radiation - Wikipedia
I just did a quick search for a web page that discusses the difference between PAR and the other types of measurements discussed above, but about the only things I saw were from sellers of LED panel grow lights. I'm hesitant to post those, out of consideration to our sponsors. But in the end, I decided the positive (information) might outweigh the negative - so I'll post one such link. If anyone is familiar enough with those of our sponsors who sell LED lighting, though, and find something of this nature at one of our sponsor's websites, feel free to use the Report Post function and ask a staff member to swap links (thanks!).

Its good for seedlings, at 18inches its 245 PAR. 6 inches from center, you get around 120par, which is horrible.
Garbage waste of money.
Decent flower needs 400PAR, but if you drop it closer, your foot print is less the size of the light itself.
Meant for growing moss, perhaps?
.You mean PPFD? "PAR" isn't a unit of measurement.
If so, I would have thought the recommended minimum to be somewhat higher. Which... is kind of reassuring, actually (I have a low-wattage LED panel about to go into service).
what about 'Lumigrow(with spectrum control) or cailfornia light works (550 solarsystem) does KInd Led rate !!!! Looking at these three - thought's ?
are they of amason ? (45 watt panels's)(12by12 ?) have use two off them as side lighting which really increased yields !!!!Meant for growing moss, perhaps?

PAR is a measurement, its just a direct spot measurement, but yes, 400ppfd would be good, and could be great, if your area is dialed in perfectly. ppfd is just a cumilational average of par measurments thruought the entire area, and not just spot measurement.

just check out HLG for a quantum board kit. you wont have to worry about heat and will be BRIGHT! go 3000k. will be a better grow

QBs are awesome, Id like to have a set-up myself i guess, lol..
But I love my Cobs thus far.

Are you saying leds reds and blues are a scam... Because in nature it may best for the plant to break down the light spectrum it needs on its own... Kinda like go outside a getting some sun instead of taking a vitamin e tablet

Just to update, I did end up getting the Mars 1600 and used it in 4x4 tent for the first 2 months of my grow before realising it was incredibly inefficient for everything outside directly under the light.
I ended up ordering the qb132 x12 for my 4x4 and they work amazingly.

750W of QB's in a 4x4? Hope you have some co2 plumbed or some dimming because that would give you way over 1000umole PPFD. Nice rig and the growth looks marvelous.

Haha I wish I could use co2, tents in my room where I sleep. I plan to dim them to 100watts each during veg, and right now I keep them at 200watts per row to help save on energy and because I can't raise the light anymore.
I like that, regardless of whether you're under-driving your lights or running full-tilt bozo, you've still got full, even coverage and minimized shadowed areas. If you had a non-dimming setup, you'd be forced to shut part of it down if I wanted/needed to either run less lighting or use less electricity.

Thanks! I was quite happy with how it turned out :3 So far the results are amazing, i can only imagine how it would have done if my entire grow from day 1 was with this qb.

QB's really are taking over the industry as in revolution
High quality COB's are also a very good choice
I have nothing but respect for Cree's, Bridgelux, Luminous ect.
I just ordered a new QB rig and it was expensive
I'm lazy in that regard and they assembled and tested it for me before shipping
In my discussion with Kurt, he said that if I wanted a Black Dog or a Cirrus, or a California Lightworks or a Kind
He could ship it to me the same day of my order
If I wanted a QB, it was a 6 to 8 day wait
I wonder what's selling, huh?
How are those other companies going to reposition themselves to remain relevant in the post Samsung era?

I've also noticed more and more are flocking towards it, and for damn good reason. Its top quality, its a nicer white light so taking images is easy, they are powerful and at a very fair price! The pro's are just piling up. I havent had them long enough to know of cons.
