How high were you when you wrote this?Thats overkill the 1825 at 1050ma will be 40watt those heatsinks go all the up to 80watt you can get the smaller heatsinks for 6€ And also lower shipping cost.
@2100ma those heatsinks are to weak becouse the 1825 will put 117watt of watts.
You can get a pretty good idea of the lumens at any particular drive current/wattage with the datasheet. Digital analysis of the current/output chart provides a closer estimate. There's also the Cree PCT.

Interesting combination, right on the limit of my project.@MarCus M.D

1818s match or beat the cxbs at all currents and are ~$25 with holder with RIU code. i built a rig similar to mobos ove rthe weekend but ued a 1400mA driver (cause the citis are 50V) - damn near identical to mobos rig- a 320W driver running 4 cobs on 140 pinfins@ 75W - in a 3x3 tent tabootThat's my goal, minimum 50% efficiency and 160 lm / watt.
And the CXB3590 80 CRI CD BIN gives 56% efficiency and 182 lm / watt to 1400ma.
How would a better combination with some Citizen COB? My idea with the 3590, is make 400w(8COBs), 200w(4COBs) each for a 3x3 tent.
Each cxb3590 costs me $35 with adapter, reflector and thermal paste from Jerry.
good for +2-3% eff usuallyIt's a 3x3 brother try not to over think it you have light bouncing off the mylar etc. You want eff wire in 240V that's what I did. Not many of these guys do that they argue eff and operate on 120V....
When you can run twice as many lights per breaker because of amps that is much better if your grow needs it.good for +2-3% eff usually
read your datasheets, peeps
240v/480v lower voltage drop due to lower current, 2-3% maybe and will mean diddle shit on the utility bill........good for +2-3% eff usually
read your datasheets, peeps
Fine with me won't change my response smart guyoh and crybaby im putting you on ignore so you can talk but nobodys listening.
Thanks for the math now I dont have to do it. Now you can easily see in black and white how you can run twice as many lights on a 240v setup vs the 120v. My driver's run cooler than in the 120 as well found no need to remote mount my driver for the diy light with the 240 I can leave my hand on the driver all day long.Amps X Volts= watts..................you know what the electric company goes by, not gaining efficiency with 240v
120v x 10.8 a= 1296w
240v x 5.4a = 1296w
Yeah I switched to 240 a while ago, worth it all day. Just for less runs of wiring.Thanks for the math now I dont have to do it. Now you can easily see in black and white how you can run twice as many lights on a 240v setup vs the 120v.
