LED Companies w/ LINKS

a customer sent me a link on this and I liked the concept, then I saw they were using low cost P2 china leds and was a bit disappointed, It seems to go to this amount of design you should be using top quality diodes and maintain a combo of output/eff without any concern about thermals, Cree or osrams at greater density would work beautifully with these
cheers
Mr. Cutter,
Thank you for your post. I sent the company a request for more information on what diodes and bins they use and received a sales brochure filled with repeated information from their website. No facts just sales patter. I agree with you the concept has merit but the materials used do not. Shame really.
I can see vertical food production with high efficiency luminaires becoming the norm in the not too distant future. The initial financial outlay for a system as large as they are selling with quality diodes would be what double or triple?

Cheers,
Will

@welight,
While I have your attention, a question if I may. My experience with mounting LED onto PCBs is nonexistent. My question about that particular form factor was motivated by my interest in upcycling some old chinese PCBs I have laying around with better LEDs. What do you suggest my best course of action to be?
I have a feeling you may suggest that they suitable only for the rubbish bin. Your thoughts would be most appreciated.

Hi Will
One of the things I have noted on this forum is the general poor opinion of the Mars Hydro product. I have helped some customers retrofit these units with COB's, the notable issue with them is they use these leds, possibly Bridgelux or a china equivalent and they seem to have a habit of 'browning' out most likely due to poor thermal design, I assume if you have a good thermal platform you could use them. The other thing I dont care for is they normally have an active slug base. If yours are functioning ok then with good thermal control no reason you cant use them. are they as good as Cree product, no they are not but the cost to convert the board relative to buying new boards would not make any sense
Hope this helps
Cheers
Mark

Like garage sale signs up 2 days early and stay for 2 months afterward. It's a new world since this thread started over 3600 posts ago.

Only DIY. Timber grow lights has simple diy kits. All you gotta do is string them up or frame them. Too easy. For flower I'd add his 660 red kit also. Would be epic.

I will be ignorant, because well in regards to lights, I am, which ones and how many...
