For commercial production, its good when they stretch a little. There's more distance between the leaves and grow medium, making it easier to harvest them. For my setup, I'm trying to match the output of (4) 34 watt 4' fluorescents. I'll need to do a comparison with T5 bulbs and wattage, to...

What were you running the Veros at Amperage wise? I'm planning to use a lot less veros than what you had...damn. My setup is going to be 4 per 8x2' shelf, running at 350 Ma. Each vero is covering approx a 2x2' space.

Dude, that would be sweet. What length of shelving were you covering with the 50 watts?

I found this website usefull to understand heatsinks in more depth, if anyone is as confused as I was/am about them. http://sound.westhost.com/heatsinks.htm

Alright, So I received my COB and drivers, and I'm still looking for a more cost effective heat sink option. I'm considering using CPU heatsinks, not the thin finned ones. I have access to used heatsinks for AMD CPU's at $1.20 a pound of aluminium. It would cost me about $30 for all the heat...

Thanks Rahz, I just put in an order for 32 Vero 10's and 2 HLG-120H-C1400B drivers. I'm confused as to how to select a proper heat sink. From what I gather I'll need approx 5.5 watts of dissipation per COB (350ma x 25.7v = 8.995 watts) 8.9 watts @ 38.5 effficiency = 5.4735 watts of heat Not...

Never mind, just noticed the input voltage is 180AC.

Would this also work? ,its slightly cheaper (ELG-150-C1400B) http://ca.mouser.com/ProductDetail/Mean-Well/ELG-150-C1400B/?qs=sGAEpiMZZMvw41ESBAosLJst3x15QJSOpkRxrcJtjZQ%3d

Hey Bicit, Im curious to know what these $1.50 drivers are, also were you running the vero 10's with out any sort of passive/active cooling and still achieving around ambient temps?

Thanks for the suggestion. If I wanted to get a good driver, what would you suggest. Thanks, I was considering using on off the shelf LED light, but the price is so close for a 4' section. I figure my diy will provide more light and be much more efficient. DLI? I assume that is the amount of...

Hey, im looking to build a 4 tier shelving unit for microgreens and have it lit by vero 10's. I'd like to wire them in a series/parallel combo. I'm thinking of doing a series string of 4 LEDs and have those 4 strings wired in parallel. Is it possible to use a single driver to power 16 - 32 vero...

Hey thanks for the great info, the amount of info on here is daunting to sort through. I like the reason you choose that particular 5k, I did look on digikey and there are 2 other vero 10s with those same requirements and at the same price point. The spectrum seems to be identical for all the 3...

Abiqua, dont mean to dig up an old thread but i want to do a build very similar to yours. I'm looking to grow microgreens with vero 10's. Why did you choose that particular vero 10? there are many 5000ks. How did the build work out for you?

Keep me posted on your progress. Thanks for the suggestions, I took look at the Vero 10's (5k spectrum) and they're what I'm looking for. The 13, 18s seems to powerful for my application considering my height restriction (14"). I'm thinking something like this...

Hello Rollitup, so i'm convinced LEDS are the hottest thing since sliced bread and want to get on board. I run a small microgreens business and I'm looking to convert my recent growroom into a full fledge LED Grow. I have 192 feet (58.5 meters) of shelving that needs lighting. I was initially...
