How wide of light does this throw? I want to hang it in my 4 shelf greenhouse. Shelves are 19x27. I assume one light per shelf will be enough, right?

It all depends on what you are using them for but I would say 2 per shelf or the plants will bend towards the light. The blue light is for growth. If you will be using the lights after the 3rd set of leaves you will need to switch to the blue/red panel.

I have mine about 10" above seedlings, and honestly the light does not spread much past the 12x12 frame. But they are growing like crazy!

I use this light to illuminate a 4'x4' tray. The plants on the very edges all lean inwards towards the center. I went to a different reflector, 24"x24" and this eliminated the plant lean. I think the reflector would be good for a 3'x3' grow at max. The ballast and bulbs are good though.

I have mine on the corner of a two stall garage about 9 or 10' above ground it give enough light for about a 4 stall area. Nice white light. Not sorry for my purchase

i use it on plants that i keep in the garage over the winter. i do use several at the same time. i also use 48" florescent grow lights.

It is about 18 inches long and puts out a lot of light, but may not be enough for a full 36 in long stand. I would say it would depend on how high you need to hang it from your stand.

We have one on our 55 gal. tank which is 48L x 12W x 20H. I would recommend you use two for enough light for your tank. One is adequate for our tank and much brighter than the flourescent fixture we had previously.

I installed mine in a 12X8 tool shed and it works just fine. You barn is quite a bit bigger though. Installing one of these will probably just give you enough light not to trip on something at the furthest point away from the light. I would recommend installing two.

I use it for my greenhouse which is 14 x 8 ft. It is very adequate for moving the air in there and could handle a larger one easily. Seems to me that it would work well for a room up to 20 ft square. It was very easy to install, just follow the directions. It is very durable and has taken several years of abuse in the hot Idaho summer. I really like the remote contral for it, as it is mounted high on the greenhouse wall. I bought it because it was highly recommended for greenhouse use. The price on amazon is the best as well.

My plants were about 2 ft from the bulb and did well. So one bulb could cover your two trays side-by-side, maybe even end-to-end if you swap them around every few days.

I have 1 unit on my tank which is 3' wide x 2' deep x 2' high. one light is fine; the edges fall of a just a bit but for a 6' tank should be good with 2 lights. I have it set to only to 65% at the highest as the light is brighter than my old T5's.

I have two 1000 watt lights but I took the glass out of the hoods I haven't tried anymore than that.I would recommend hanging the lights before you put your plants in if you want to try more than that to see if the structure can handle it.

I have one mounted on an alcove wall that is 23" wide. You can extend the light full length or adjust it to bend at the center of the long pole (as shown in the photo). I have mine bent slightly and it works well. The other light I have is fixed to a wall over a desk and works great for adding light when you want to work at the desk. The dimmer works well for this reason. I am happy with my purchase of these lamps. Hope this helps.

I have it in a 12x12 room and it has a large window, so it puts off good light. But if the room was much bigger I would think it wouldn't do for single source light. I am in love tho with this chandelier!

Should be ok. As suggested, you may want some floating plants (like duckweed) to filter the light if it's too much.

The picture we light with this is just 24 wide and 30 high. I agree with what T says, it's not going to be enough light on the picture you want. We have other art in our home that we use electrical light fixtures and they work perfectly for something of the size you refer to. One is similar in size to what you mention and we use about a 26/28 inch electrical light on it.

I found it once, but don't recall now. I've installed these in most of my closets. For the large, 4x4 closet, it lights it up dimly, but well enough to see by. For our pantry, I installed one light per shelf, and the light is incredible.

They give off a lot of light but I think two would not be enough. All depends on how much light you are looking for. I think four of these would be much better
