Damn! 85 bucks. Fancy fuckin meter!
You can dial em back but they don't get any louder when you turn em to 11 and rip the knob off.....Ok power supplies... Hlg 185 c1400b?...push em at 1250 wired parallel? or go hard and bang the 240h-c1750?
My suggestion world be the elg-240-54-d2 2 cobs per driver 2.2A but if I was choosing between the 2 240-1750Ok power supplies... Hlg 185 c1400b?...push em at 1250 wired parallel? or go hard and bang the 240h-c1750?
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 ..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?
Holy shitThat ppfd will be about 1100 and since you are adding co2 you will the the most out of it
Yeah probably closer to all 1100 given all those 90 cri I got as well, eh Qball.That ppfd will be about 1100 and since you are adding co2 you will the the most out of it
1125 to be exact for my roomYeah probably closer to all 1100 given all those 90 cri I got as well, eh Qball.
Too soon?

I think I'll be shooting for here.. I have some power limitations here...That ppfd will be about 1100 and since you are adding co2 you will the the most out of it
Air chuck? you mean the NPT FIP BUNGHOLE on the end that looks like an outty-belly button?If im seeing the air chuck coreectly, You might want to consider plastic connectors like this

That be the one, unless I'm seeing it wrong it's the water in or out heatsink?Air chuck? you mean the NPT FIP BUNGHOLE on the end that looks like an outty-belly button?
the elg 240 54B fits nicely however it locks me into future choices down the road......I like the flexibility of the currant drivers...My suggestion world be the elg-240-54-d2 2 cobs per driver 2.2A but if I was choosing between the 2 240-1750
