My Son-in-law birthday gifted this to me. It's a 300 watt led grow light. I have never seen such a light. Has 3 cooling fans:) Very bright! Actually, "very bright" is an understatement... "blinding bright" comes to mind.

Anyone ever used one? Would probably make a good room heater as well.

No personal experience, but...
My son-in-law tried this for a while but found the color of the light too eerie; they discontinued using it. Perhaps it would be better if not used in the living area of the house - like out in the greenhouse?

Edited to add:
This is the LED light he had tried:

It is almost hard to look at in a picture. Interesting.

No experience with lights. Hubby "request" I stick to only the two windows in the den for growing indoors. Can't complain since he is letting me take over the yard!

Greene, the light your son-in-law has/had, is very low wattage and would only be suitable for a very small space. Do you know whether the light(s) is water-proof. I use numerous LED's, but they are all water-proof.

Frank, that fixture is really huge, considering it has all that wattage and needs three fans. I would have loved to have invested in one such as this (when I experimented in LED's) but because of the expense and the lack of water-proofing, I had to go smaller. The lack of water-proofing was the real turn-off though.

These colorations are really, really weird and yes, they are bright. Talk about bright though. You should put a six bulb, T8 fixture alongside a 6 bulb, T5H fixture. The difference is almost like night and day. I would never have believed the difference in light output if I did not have these fixtures in the same greenhouse.

I read a lot on the web about people using LED lighting in the greenhouse. It's an interesting concept to me.

I think it's very interesting because last week I started to look into going the LED route. Frank, let me know how you like it, please. They are expensive and I am worried about picking the wrong one. All the testimonials I have seen so far are from the companies themselves...more research needed.

Anyone know yet if the plants grow faster, or stronger?

Arlene, I have eight LED fixtures, but because of my greenhouse size, I have stacks of shelves and thus needed water-proof LED fixtures. I don't know whether they are very effective to tell the truth. I have had them for almost a year and can't really tell your that that make much difference. I wanted to supplement my lighting on the second and third row of shelves, and that's where I use them. There is no way I can give a comparison of using these LED's and not using them. I simply have too many variables. I wish I could be more help.

What about cost of lighting? Did you have lights there previously? I'm really interested in the cost for usage as well as performance for lighting. But that pink would be kinda hard to take.

Well since mine are all in the greenhouse, the color is no problem. Besides, those particular LED's are below the line-of site. They are very cheap to run, even less expensive than fluorescents. The problem is in the cost to purchase them. They are not "cheap"! Sticking tongue out

Yeah, I know but I think if I "invest" in one a year it's a good way to change over. I just have to really look at them and decide what to get. I don't think I would need waterproof, but then I do set up a five shelf rack to do seedlings on so maybe it would be better. I can get kinda sloppy.

Those that have higher wattage and thus require a fan(s) to cool, can't be waterproofed. I have two shelves above the LED fixtures I use, so there is a lot of water dripping down from those upper plants. If I had it to do all over, I would search a bit longer for higher wattage units, but still knowing that they had to be waterproof.

These lights were purchased in 2013, so I don't know what you will find now. They were all 11W waterproof fixtures and considering the low wattage, they were very expensive.
