Thanks for the links. I have see them all from time to time but it's nice have them in one spot for reference. If this driver can run 5 cobs I think 5 cxb3590 36v running at 1.4 amp will be good for a 6.66 sqf area. That should put out about 143 par watts meaning 21.4 par watts per square...

Okay so they all run at an even 50 watts. Is this okay for them to get 35.8 v? Is it hard on the driver ? Good for it ? Okay for the cobs ? Will dimming be a problem ?

The hlg240 1.4a runs at 250w 5 Crees at 36v require 50.4 watts. Is it okay to run 5 Crees on this when they require a total of 252 watts? Will the last cob on the line suffer from low voltage ? Thanks.

Thanks for the heads up. The product said 3 in 1 dimming so i thought 1 supply supported all types. Definitely going with potentiometer dimming so A is the right one.

Thanks. 3597 was a typo. I djdnt realize there was B version. I assume just the addition of dimming? I'll have to look into this. For heat sinks i was thinking to go passive and the website ranks theirs cooling capacity in watts. I was going to go a little larger than needed for power it...

Interesting. I never considered an extra cob. That would have the fixture putting out 197 PAR watts and 33 PAR per square foot when run @ 2.1a Thanks airwalk. Is there any problem putting an amp meter inline with the cobs so you can see what you have dimmed them too? I would think putting it...

Trying to design an LED all purpose (veg/flower) solution for a room that's 24 inches by 40 inches wide by 5.5 feet high. That's 6.66sqf of floor space. I have it almost figured it out but I want to run my thoughts past you experts and get some opinions. I think all the parts will come from...
