Would a vero 13 with like a small 10w driver be good for seedlings and clones? Plan on running it 24/0. It's probably under a sq ft total so it's small.

Figured I'd just slap it on one of them alpine heatsink fan combos things.

Would that work alright?

Yes, well maybe, I don't know what the Voltage forward [Vf] of those cheapo's are....

I would run the 30w [$10] version with a Vero 18 @ $22 [$10 Driver + $12 Vero 18]..probably about the same price as the cheapo setup and double the output.....

Don't waste your TIME with cheapo's,Please!.................... they are not Grow Quality LED's imho, but they make a great light when hung 50 feet above an indoor basketball court :peace:
It's no worries there, I won't be going with the cheapo setup. I'm trying to get my head around it. If I go with vero 29s (BXRC-35E10K0-L-23 these ones) and I wanted to use 2 drivers what would be a good choice. Or can I get 4 to run on one driver? And what are the benefit of the lenses. I only have a 50cm deep tent, will they help with wasted light if I got a narrower beam angle?

Each Vero 29 needs 36 volts @ 1.05 amps and 37 volts @ 1.4 amps....

In a series connection, simply add the voltage together, but current has to match....

The MW HLG 185 1400 puts out 132 volts.... The 4x Vero29@1.4 amps draws.... = [4 x37 volts] 148 volts...So the HLG is 16 volts too short to run that series.....[That's why 3 is the max.....[3x37 = 111 Volts + 21 "free" volts

The 50w drivers from my link are a good choice for $12....you need one 50 watt driver for 1 Vero 29....Max 38v's.....Impossible to run 4 in a series...because the voltage is sized for just one diode.....

No lenses, not at that height....Try to get as much distance as you can to spread and let your cab act as a reflector essentially........I run no lenses in a 75cm Tall Cabinet with 15-25cm of distance from LED to plant tops.....

Thanks for the thorough explanation. So the total forward voltage/current of the chips combined has to be less than or equal to the output on the driver? Just to wrap my head round it....

And I have 1.8m high tent. 1.0x0.5x1.8m I want to build a fixture around 90cm long and have 4 cobs along the length of it.

Yep......when a driver doesn't work it will either not light up the diodes or make them rapidly blink....

Might want to go Two rows....One row is pushing the coverage for .1/2 Meter space....unless you run them around 2.1 amps each...:peace:

And how much would that increase/decrease efficiency and same with regards to wattage / voltage

View attachment 3499490

Roughly 3% loss in efficiency going from 1.4 to 2.1 amps....you can see the vF increase in the chart....
While gaining about 50% output [75w roughly over 51w roughly]

So if I ran 3 at 2.1 amps it will consume roughly 225w in total but I take it extra drive will reduce lamp lifespan. So really I could run 2 lots of 3 vero29s at 450w in total in my space??

Ty for the spoon feeding. Makes it easy when people explain it simply.

After reading those charts I realise it's not as hard as I first though

Sorry meant 2 lots of 2........rather than more diodes, spend a lil extra for drivers....the Vero's like to be driven hard and that efficiency is best of the bunch HPS territory....Still Great/Excellent

What do you mean by mono panel? The platinum led seem to be the best warranty and price on a true full spectrum around....
using "white" & monochromatic leds to get their "full" spectrum................warranty means shit when the diodes are inefficient. Ask platinum for group/bin #s on b-lux/cree/epi-whatever used in their fixtures and see if they get back to you?........ill wait:eyesmoke:

So for a prebuilt system, one of the 3 sites you listed would be much better than the platinum leds? Is there one you would suggest over the others. I'm wanting the best, don't mind paying for it ;)

out of all the pre-built cob fixtures available, I think GG's pacific light concept cx300 is overall the best you can buy for the $$$ atm. Only top quality components used and a manual dimmer for summer months makes it a winner IMO. cob spacing is good and the par #s over a 3x3 should handle flowering cannabis efficiently ......i haven't personally used it, but the cree cxb line has shown to be very capable over & over in here.

good luck

overpriced inefficient mono panels, good old hid will crush them @ quarter cost. quality cob based panels are the best bang for your buck for pre-built or DIY.

Hi, what's your guys' opinions on platinum led grow lights? I'm looking at the p450.
Look around for the pled thread. Plenty of info about their outright bullshit and deceptive practices.

Their cheerleading squad over on 420 rides the short bus of led gardeners.

Thanks guys, really appreciate it. I will definitely post up a thread when I get it going. Someone I was talking to mentioned you don't have to feed as much? Any truth to that statement?
