I've also used galaxyhydro leds. They seem to have worked quite well. My babies vegged like crazyI'm looking for an LED light in the 500 watt range and was wondering if anyone could recommend something. I see the prices range from $50 to $1000! I'm looking for something low cost to compliment my Mars Hydro 600 for a 4x4 grow room.. Thanks..
Yeah my mars says 350 watts so that's about right. I have a 1000W HPS light on my 4 plants right now but its too hot and expensive to operate. Plus the bulbs don't last and they want $60 a piece for them! Not worth it to keep running it. Do you think another LED like the one I have would be enough for the four plants..
I'm considering this quantum type. You can use it to evenly cover a 4.5' by 4.5' in flower. Suppose to be the most efficient. And it will dim down for my 3' by 3' area in the summer.
Or maybe a Spectrum King 400 plus with a dimmer. It will easily do a 4' by 4'.

Well I think this one just might be the best one of all. Very efficient and you can adjust it to whatever you want. 4 separate COB lights. No fans.

Your Light system looks great! Those things fit right up at the top of the tent. Probably could grow some taller plants.4 COB's with lenses and heatsinks, 2 drivers and some framing for $850, no freaking way...
A high quality COB costs lesss than $30, lenses are maybe $10 each, heatsinks $10 each, a driver is usually $60 - $100, aluminium framing is a dime a dozen in hardware stores.
Edit -> I saw they use Luminus COB's, the latest gen of these are $22 a piece, they don't write what Kelvin they are though, we kinda wanna know
Here's some basic DIY rules of thumb:
Look at Kingbrite's alibaba site, they have components and kits
Soft vs. Hard; Using many COB's at lower power is better than running a few at high power.
The COB performs better (light to heat ratio) the more points of light gives a better coverage, less heat means longer life of each COB.
ALWAYS GET PREDRILLED HEATSINKS!
Use meanwell drivers!
Dimming will result in lower driver efficiency, check out the datasheet on your driver to see how it affects your design.

But you talked me into it. I bought the Migro 400. I'm a technician for a living. The last thing I want to do is reinvent the wheel to save just $400 and end up with a rickety prototype.
This guy has his turned down to 75 percent power in his 3' by 3'. If I want I can upgrade to a larger 4' by 4' and still have a high enough PAR.
