DiY LEDs - How to Power Them

I found a good deal on some surplus ecoplus 40w led clearlight replacement lamps ($30.00 each). Can anybody give me any idea how efficient they are compared to similar power sized cobs, T5s and 150w HID lighting? Unfortunately they are 6K temperature so use is limited to veg or supplements for flowering. I got a couple to test out, so far impressed. crisp cool white cree leds drawing 44 watts at the plug. No fan for cooling and only warm to the touch.

They're about 17% efficient with street lamp-like (bat wing) angle of radiation.

ok I get it, thanks, btw the surplus lights don't have a batwing shape, they are nice and round

Nah you don't. The point is bat wing-like angle of radiation (the actual graph I posted).

But when I think of it....it doesn't have to be a disadvantage. In fact, such distribution could give us the best spread.

isn't a bat wing footprint oval in overall shape ? I don't know how to read the bat wing graph.

The spread I see is like a circle without a center focus point, is that what the bat wing graph is showing ?

So I have 3 cobs powered by one driver and 3 fans powered by one driver each.

I'd like to have everything connected to one power cord to the wall.

What do I need / need to do to make this possible?

Thank you

Get enough/big enough wago connectors to that you can put all your positives(hot or live) together and then all your negatives(neutral). You can use a wire to connect multiple wago's if needed. Then just have one wire go from the wago's to your power cord/plug.

With AC power...everything is to be wired in parallel.

The driver data sheet has the info..

I'm not really familiar with every driver, I just looked quickly. Should let supra give out the driver info..lol. The initial spec i saw showed the voltage on the hlg 120 .700ma only enough for two 72v 3590s...upon review of datasheet it can run 3. Might be other combos yet...does take time to zero in on the perfect driver.

I couldnt find any steals on the hlg 120h-c700. I shopped around and ended up going with a pair from China via Dhl for 130 total.

Super excited to move ahead with my DIY. Learning new stuff is still a thrill even for this old bag o' wind! I didnt even know the vocab when i first dropped in @ RIU. Very grateful guys. Next step is grabbing the cobs, holders and lenses from Kingbrite.

It is too hot to flower here in Summer so i gots some time to assemble it carefully.

Hello! Is there any 175mA driver for Vero10 because I read somewhere that is not good to run them in parallels. Or should i take a 350mA one and make 2 lines, this way if one of the line take all the power it is not going to be a problem. I have to look for the vf of Vero10 i believe it is 33.
If i found a 100V output driver does it means that I can put 100V on each line of cob? So 2 lines of 3 cobs on a 30w 100V 350mA driver!? Am i good?
Thanks and have a good day★
