In the ms0006 there are epistar leds, which is a great led manufacturer, but i cant find anywhere the datasheet of the Epistar 660nm 3w chip. The best 660nm led is the Osram 660nm
http://www.mouser.com/ds/2/311/H_W5AM_Pb_free-19333.pdf , i know, couse i read the datasheet. Do you know anything about the Epistar 660nm? All of the led drived at 700mA, but its good couse they use pulse techonogy, where they turn the led on and off like 10.000times in a seconds. For example if u drive the Osram 660nm led constantly u can do it at 400mA max, but if u use pulse technology u can go up to 1A. So this is a big plus to Grownorthern!
Also They told me that their white led can produce 110lm/w. The 3W White led produce 220lm at 700mA.
So 220lm/110lm/W=2W 2W/0.7A= <3V. At this moment the olny led what can do this is a Cree led, couse Phillips(Luxeon, Rebel), Osram have never went under 3,3-3.4.
So they use Cree LED, or The Bridgelux know sg what we(customers) dont.
For the Record: I love this Led Panel, and i think this is one of the best LED panel on the market, but I need some answers for this question, to know what I buy, but at this moment they doesnt really want to answer me... It means this is a secret what makes me say: OOOOO C'mon! How could I buy a LED panel where The 660nm LED chip is a secret! This is the most important part of the LED panel! Or That chip... not the best... Honestly, I dont think so. The epistar is a good manufacturer, and pobably this is a new product. I saw some Epistar 660nm 3chip on the internet, but the shop can write anything about it, couse there is no law what can punish them if they lie. The only way to get correct information is the datasheet. So where is that datasheet?
