how close can i get this light to the top of the plants?

I never kept it closer then 12-18 inches. A lot of people are misinformed and put high powered LEDs to close and end up bleaching out the plants . A Google search will show that around a foot is optimal ..... Your not losing light

Hi, I had this discussion with a buddy last night, you don't want to get too close, you will stunt the plants growth (it will generate roots with very short foliage, because there is no need to stretch at all for the light). I would not go any closer than 20 inches after the first few days after germination. The first few days the close light (8 inches away) will warm and blast through the shell of the seed.

Right to the top if you want. The face stays cool to the touch. It has three small cooling fans to keep the leds cool. I have two of these and they put out great light. I'm gonna get one more for next winter.

After having this light on for hours, it is still cool to the touch, you can get it half an inch from the top of the plants without wilting. I am not sure it would be the nominal height to get the most out of the light though. I would not exceed 3 inches to the top of the plants, or you would just be wasting the light.

This model is a bit small for your area of cacti. I would recommend locating a larger light that can cover more square footage.

I would imagine that you'd be ok with this light. I have one 48" fixture on my 75 and my stem plants grow 1/2" a day. Not quite as deep as yours but this light is pretty bright.

I have them mounted bout 14" off the ground. They will trow the light a easy mile. The light expansion isn't bad but they are more of a spot than a flood.

69 in from base of the planter to top of the lamp. The solar lamp work well but dos not illuminate the area too much. If you need to illuminate the area I recommend you to buy another type of lamp.

You could get the top of the shade about 7" from the ceiling. It might be possible to get the top of the shade closer to the ceiling, but we did not try that.

Probably not, you will most likely need the LED indicated for plants, it has a different light spectrum

I recommend that this light only be about 2 INCHES from the seedlings, not two feet. Spindly plants are due to insufficient light.

I don't think the light is bright enough to do that. Need to use it for things up close.

We have had very good luck growing seedlings with this light, have it set up about 2 feet above pots.

I don't know how high the light will go. I just have them turned on some shrubs.

The general rule of thumb is 12 to 18 inches, the best thing to do is hold your hand under the light to judge the distance, if it's too hot for your hand it's too hot for the top of your plants. It also depends on how many plants you are trying to cover with the light, keeping the light 12 inches above the plants allows the light to spread out into a wider footprint over your plants while keeping a good intensity on them.

8" from the top of the loop to the base of the fixture. If you don't include the loop, 5" from the top of the fixture to the bottom Hope this helps! I have two of them, one hangs and the other one sits on a flat stone in my flower garden. Both provide nice lighting.

somewhere around the perimeter on the top. put as close as you can to the edge ,otherwise there will not be enough clearance for the light to fit properly

You would have to raise it really high to get light over everything... Hint , leds with reds , yellows , blue, violet (full spectrum ) grow coral good..

I agree with the previous response. From the ceiling to the bottom of the light is between 18 -24 inches.

Plenty of light for that depth. I would say enough for medium plants. You could probably also do the ray2 if looking for more alternatives.
