Obvious your ducks are in a row and saluting and quacking their asses off!!

Please don't take offense when I bring this up again but why not use epoxy for the cob chips? Is it cause you want to keep it flexible?

Godfather420 · Jan 11, 2017

Ok power supplies... Hlg 185 c1400b?...push em at 1250 wired parallel? or go hard and bang the 240h-c1750?

You can dial em back but they don't get any louder when you turn em to 11 and rip the knob off.....

My suggestion world be the elg-240-54-d2 2 cobs per driver 2.2A :hump:

but if I was choosing between the 2 240-1750

That ppfd will be about 1100 and since you are adding co2 you will the the most out of it

None taken. I'm trying to build a platform of modular design.... I'm fucking tired of Bleeding edge technology... But I love technology... How to win? Build things that don't become useless ..

Whats in store for LED, only the manufacturers know.... But what ever way they wanna serve me LED, rest assured my light will be able to have that new chip or custom quantum board strapped to it. :bigjoint:

Yes, too answer your question simply :eyesmoke:

When comparing the current power load at 16-600w lights call them 625 = 10kw That would actually be more expensive.. :clap:

the elg 240 54B fits nicely however it locks me into future choices down the road......I like the flexibility of the currant drivers...
