Is this a Vero 29 killer?

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.

How high were you when you wrote this?

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.

That'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.

It'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....

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

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 taboot

good for +2-3% eff usually
read your datasheets, peeps

im not gonna bust out the voltmeter. pic of the datasheet should be all you need to see the +3% bump. 3% is substantial you gotta spend upwards of 20% more on cobs to get that - vs rewiring your driver which takes 10 minutes and offers other benefits as well

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.

Cheers

Yeah I switched to 240 a while ago, worth it all day. Just for less runs of wiring.
