At 160W, it looks good for small grows. Something very different for the market for sure. redish light looks nicer than purple. Entire body is a heatsink and i havent seen anything like it before so not a re-booted idea. Had to google The Aspect Grow Light to find the kickstarter that offered...

Thanks again for the information. I only see one company using high amount of far red, so I had my doubts but I figured I would ask. Our Aquaponics team really wants a product to test now, so they are on my back about getting something soon that they can tweak and improve on. Anyway, I...

Hosebomber How much far red are you using for the flowering stage? Is it safe to go up to 10 or 20% Far-red if my Red is only at say, 60% overall? I forgot to mention (since you recommended I look into this about a month ago) We are now connected with a group of master students who are...

Re: square footage VS cubic feet?.. They use square footage because the leaves on the top layer absorb/block most of the light and the ones below see little of anything. If your light is above the plant, it will hit the top leaves first and stop, so square footage is the most useful way to...

Thanks, I am very interested in this material. A natural-convection heat sink for this wattage is not an easy design tho. The only flaw I see so far is the Thermal Conductivity of this plastic is still awful. Some of coolpoly's are only 10W/mk - 100W/mk (but I did not see a data sheet for...

Sounds good man, Thanks a lot for your input! Very helpful, you have no idea. As for the 730nm being the peak wavelength, I have access to nearly any Red/Far-Red wavelength; 670, 720, 730, 740, 745, 750, 850, and 940. Thanks for the input on the 60nm difference. I am still working on a full...

Hey all, I want to get your feedback on the 730nm spectrum and how that is affecting your plants. I am new to this field but I think it is important for everyone to understand. (Especially me). One thing that I find interesting is a lack of conversation on this. Far Red (730nm) it is...

As an update, here is the progress. We are open to any comments or suggestions. We are getting custom 20w COB chips made that contain this spectrum. 430nm, 440nm, 450nm, 470nm, 630nm, and 660nm. We plan to be able to control both the red and blue spectrum separate, then users could...

Thanks for the help, I will check them both out.

Hey All, This is just a friendly update: I am finding it difficult to find an LED with a peak of 640nm. I might have to find a solution to this, I think 640 and 660 are pretty important and both should be used. 630nm could be used, but it is so far from the critical points that I am...

@raziel819, It is sort of a hard question to answer. I think the link hosebomer has will be the easy way to explain it. PAR only tells you a measurement of all light between 400 and 700nm. If the company is low quality and wants a high PAR number, they can use LEDs that increase that number...

Thanks for everyone’s response! Very much appreciated. I know the last thing anyone wanted to see was another thread about this topic, so glad people were able to answer my questions. If I have more questions, (and I will), I will let you all know. I am glad to see the support! Most of you...

Hi All, I have been reading 100’s of topics, scholarly articles, and comparing some existing growing lights but everyone seems to recommend different things. This leaves me with some questions, so I hope someone with more experienced can roll one up and help me hammer out the details so I and...
