Yes that sounds about right.
Was lucky enough to get my hands on some of the biggest the CXA3590. These are the top bin 5000K (150W) COBs. I installed them on Arctic CPU coolers 92mm fan. The $3 driver on the left runs at 250mA. The COB puts out of 200 lumens/W at that current. The drtiver on the right is adjustable from 100mA to 650mA. At 650mA it dissipates about 50W.

This is amazing, I'm using LEDs for my personal garden and am enjoying the results. Where can I learn how to put togethera COB lighting system, how the compenents work and how to assemble. Please teach me the ways of the force.
Thanks
Wondering where you were at with this comparison? more 1050 or 1400
I read somewhere i believe in green genes thread something about them testing 3000 k , they found was not even worth it i can't remember what it was but it clearly showed that anyone should not even bother 3500 k is starting pointBeen to busy to really do anything at home.i did build a 4 x 75w fixture using 72v cree and the 1050ma drivers.its bright as hell and im glad i went dimmable because you dont want to work around or under it on full power lol.
My next project will be 2700k fixtures with a few 3000k on the middle bar and some 5000k on the outer bars.but i will prob stick with 1050ma on those and hang them right beside the bars i have now for a proper side by side
Wrong 200w of CXB3590 will replace 400w of HPS and the setup would be around $400 and misc parts would be another $50 at most and 200w if you knew what you are doing will get you about a 1/2lb so it would pay for itself the first grow.a gram of smoke cost around 10$
50 watts per sg foot at around 100 dollars a square foot for setup of led cob.10 harvest before return on investment.
sure hps will cost more due to heat but around 12.5$ a sqft.for setup.so 2 grows pays for the light.seems for the average joe,hps is still the overall best setup.
heat works great in winter,so only other cost really is summer a/c or vent fan.
am i missing something here?
yeah i dont get your math.i have about 1200.00 into my 3 bar cob setup and the first plant i pulled under it was a new strain for me that yielded 10.5 oz and @250.00 per oz i think im covered on those leds.plus the second plant looks to be a solid pound or more so idk,seems legit as hell to me.i woulda had the same size plant in that spot 4 months ago but it was being lit up by 2 x 600w hps on a mover and now its being lit by 540w of cobs instead of 1200w of fireballz :)a gram of smoke cost around 10$

You changed the way I look at L.E.D. completely!! I want to try L.E.D. but I'm not looking to marry it I am just looking for a date. But even building a 2 x 3590 lamp starts to get expensive fast. But not if I use a 3070, a cpu cooler, with few dollar driver and just run one light!!
You gave me knowledge I couldn't have figured out on my own. I have a box of cpu coolers! I have a pile of old computers too. First thing first, a 4 dollar cloner light to get my feet wet.
THANK YOU SO MUCH BROTHER!!
