how many lights do I need for my 15 foot palm tree

That will depend on many factors that are more customer specific. They measure 2'x8'. I would measure the trunk diameter of your palm tree and see if one will be sufficient. I would imagine you don't want them to go higher than 8' up the trunk, since two of them would take you to 16' and you only have a 15' tree. That would create some overlap. Hope this helps.

Depends on what and how much you're trying to grow. For one plant this is great, as the number of plants increase you will eventually need more lights.

I know it is late but maybe will help someone else. If you just plan on germination and a short stay under light may want to go with a 4 bulb T8 will use only about 60% of the power. If you plan on them being under them much longer then a couple weeks then you need the extra light. I personally use 6 bulb T8 for germination over a 2' x 4' tray (4 1020s) which is about 24w per sq ft. Then for growth, which is any point past a month, 8 bulb T5 for 55w per sq ft. Keep the lights close to prevent stretch.

I don't think that four of them will be adequate lighting. You will need at least 8. Four for each side on a pole. 12-16 would be optimal.

Lights are approximately 15 inches tall and stand about 12 inches high when placed in the ground.

2-4 would be safe depending on how far away from the plants they are. It's pretty bright.

The light gives off 15,000 lumens in a broad spectrum (Kelvin number) including UV light which the plants love.

Don't purchase the lighted palm tree!! My lights burnt out 3 months after receiving and the company does not stand behind their product!! My old nor last 7 YEARS before rope lighting went out and this one lasted 3 MONTHS!!

I went out to get the lights which are still in the box to see if they looked to long for an 18 inch tree and I realized the seller had sent me a strand of 50 instead of 35. I didn't use them for the intended purpose so I hadn't noticed I was sent the wrong thing. Therefore I can't answer your question.

Can't tell, there are many facts, hight, palm tree size, light around, how much light you like to see. Usually it take a large canon lamp or two one on each side and installed half way up on trunk. Hope this helps

I have four of these and light 100ft plus tree trunks at night with 25w bulbs (one light per tress). The 75w bulb will easily light a 20 ft flag pole. Don't think it's rated more than 75w.

I don't know much about potted palms or it's light needs, but based on the small diameter output by this bulb I would guess not.

It is not very bright. i have focused the lights on a tree but the light hardly reaches the leaves. the max you might get is 2 feet

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.

these cover about 3.5' foot radius area at about 12 to 15 inches above plant with good growth, I eventually found they do great at 6-7 inches but coverage reduces to around 2-2.5 foot radius, most of the ufo styles have similar coverage , that will help you determine how many you will need. I think 2-4 lights will be good coverage ,,have had great growth and would definitely buy another
