So much usefull information!! thank you! Anyone has anything to add to this? All information is welcome! The thing is, they told me you can up or lower down the efficiency. But to what costs and/or advantages?

Hi all, i want to build my own led array, and i am in my information gattering fase ;-) There are many things that i still dont understand, but these things bug me most at the moment: How do i calcute the loss and efficiency of a CREE Xlamp CXB3590? How do i calcute lumens ---> PPFD? (the...

any you recommend in particular? ;-)

I understand, but like i said, its a real pain to read trough 186 pages of stuff you barely understand yet ;-)

can someone tell me how to calculate the loss/efficiency of these chips?

Yeah what i meant was, as near as possible :D But what i am trying to understand is, if i want to build a equivalent of 1200 watts HPS, how can i calculate what i need?

Thanks! that was understandable :P But why would not everyone go for 100% efficiency? Only because of cost reduction? (buying fewer leds?) I mean, the way i see it... going for 100% efficiency is a higher investment, but pays out in the long run rite? But if i want to build a equilavant of 1200...

I understand what you mean! But efficiency is a vague concept still... Efficiency compared to what? And what number of efficiency should you strife? So if i want a equalivant of 1200 watt. I need 12 Cree CXB3590 COB LED's. But my efficiency will be only 45 %? If i want 56% efficiency, i...

What do you mean by that? By rating.

Hi Hockeybeard! Thanks for your answer! The advantages i seek over what i am using now (Gavita 1000watt / Dimlux 1000watt) is: Less electricity costs Less Heath Better gram per watt Why would most advise against a pre-made unit? My budget is in theorie that what the BML spyder 1200 costs...

Hi All, i want to make my own led fixture. Now i just found this thread. And as a complete Noob, it is kinda hard to understand 184 pages of "gibberish". English not being my native language is also not helping much! :-) Can someone help me with some good documentation about the principles of...
