I'm pretty sure the hlg240-700 can do itcan I run 8 3070's off one driver?

You can run 8 on 25 watts per cob i believe with 240 meanieI'm pretty sure the hlg240-700 can do it
You can run 8 cxb 3070 ore 3590 on 1 cutter 400W driver.

What driver you using?8 cxb3070's @50W (1400mA) run very nicely in my 4x3 area.
Each cob produces *approx 9500 lumens
4'x3'=12sq/ft
400W/12sq.ft = approx 34W per sq ft is what I average.
The cxb3070's put out approx 9500Lu per cob
9500Lu x 8 cobs =76000Lu total
76000/12 sq. ft =6334Lu per sq. ft.
If you have 7000+ Lu per sq. ft you are doing VERY well on your lighting in my humble opinion.
If you get 3590's you will be doing a bit better on Lu and efficiency over the 3070's. Theres an $8-$10 gap in the price between the 2 though.....
What driver you using?
Ill start ordering some stuff to switch to cobs. Ill probably run 400 watts in my little cab. Maybe 300. 400 might be overkill.meanwell hlg 185h c1400b
yes that is most popularthe bees knees has been the cree cxb3590 80cri 3500k @ aprox 50w
realtive to a 3590 on efficacy at a given watt the 1825 and 3618 are more efficient across the boardwith these citizen cobs we have seen graphs showing they r more efficent than the 3590.
see abovealso looking at the graphs from @BOBBY_G as far as efficiency goes the citizen only win when driving harder right?
1818 is the closest in the range we usually operatebut if i go citizen....shall i get the CLU481818 in the same config?
what citizen=3590?
well you can use the 105mm ones, they would just run a little cooler its hard for me to stock every possible combinationalso @CobKits how about some cute heatsinks for running cobs at 15-30w? that would make the 1212s more appealing especially in a micro situation as no optics will be used hence more cobs and more spread is more better
Thanks for ur infoyes that is most popular

1818 is less efficient below 60W, about the same 60-90W, more efficient above 90W
1212 is less efficient across the board but makes up for it with its low cost. so multiple chips can be used to be more efficient at a lower price

Aren't you running over 400 with the T5?Ill start ordering some stuff to switch to cobs. Ill probably run 400 watts in my little cab. Maybe 300. 400 might be overkill.
Yes. Even with cob I would still have a t5 bulb or two.Aren't you running over 400 with the T5?
Yes. Even with cob I would still have a t5 bulb or two.
I'm going to try to setup a couple solar panels and batteries to run it off of. If I stick to cobs I don't need drivers or an inverter. I would build the dc system to match the cob requirements. I would use three 12 volt batteries to make a 36 volt system, as an example.
I got a friend that runs those big 2 volt batteries. A whole garage full of them. He has a wind turbine to.But you will need a constant current buck converter, they are cheap though... However, modern 12 volt, 120/ah ( typical ) glass mat or gellcell batteries are designed for moderate steady loads typical in a solar home. They are very inefficient at low amperage draws. Get 6 Trojan T105, 6V, lead acid batteries. Mine lasted over 10 years of hard use.
A 250 watt panel or two, and you could charge the batteries AND run that light.
