How many square feet of coverage will this light provide?

Depends on how high above the planting surface you place the lights. I have them set at 18 inches. After one week, the plants are sprouting. That's the fastest plants have sprouted for me using artificial lightS.

2 would be more than plenty! I have one mounted only about 8 feet above the ground in mt front yard and i have nice lighting that easily spreads 50 x 100. So with two on a tennis court i think that would work well, leaving no shadows.

I think that type of square footage will need 2 lights (on opposite sides of the room) to obtain the maximum effect.

It gives off plenty of light. I am using a 75 watt bulb in both and they light up my whole living room. I think it will be perfect for your area.

I really don't know how much square footage it will cover. We only have about 10 square feet we use it on. It lasts quite a while. Sorry I can't be more helpful.

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

Save your money and buy lumatek. Apollo is junk. On average, you will need 50 watts of light for every square foot of floor space that you want to grow on. If your space is 10 x 7 (70 square feet) you will need 3,500 watts. If your floor space is 10 by five you will need 2500 watts. Spend some money on ventilation as those lights get very hot and will fry your plants. Lumatec has a ballast that will fire 400, 600, and 1000 watt lights which allows you the flexibility of changing your garden according to different lighting requirements.

It depends on the lumen output of your bulb. Minimum amount of lighting needed is around 2000 lumens per square foot.Mid range is around 5000 lumens per square foot. Optimal is 7000-7500, or higher, lumens per square foot. 40,000 lumens would be mid range for that tent. I use a 400w HPS light in that exact tent and it does the job. Then there is a matter of wattage. Judging by your 300 w rating it may do the job. Take some time to do the math. More is better than less and your plants will tell you the same.

When it's working right it'll cover that much distance, maybe not excessively brightly, but it'll cover it. But the question is if it'll work. Ours worked great for a couple weeks then the on/off button broke in the "on" position so we got a light show every night whether we wanted it or not.

All is relevant to individual expectations, but I put mine in service in a 400 sq. ft. living room and it serves well. I do have other lighting that I usually use but this comes in handy for additional lighting when needed.

Yes I be leave it will be bright enough for up to at least a 100 sq. ft. Room.

I use this to illuminate a double garage, and so there will be an adundance of light. There is also a fair amount of heat close to the lamp and so you would have to isolate it from nearby clothing, and in a confined space such as a closet it might warm the room too much. I would look for something in the 100 - 150 watt range. Hope this helps.

I guess it would work in a covered area. The light isn't that bright though. Maybe equivalent to a very bright nightlight, but with larger radius.

I don't have it right in front of me but i would say something like 5 or 6 inches by 9 inches maybe? Something close to that. I was very happy with the light, i own a Lite Panel 12"x12" which cost almost $2,500. Though that light can change color temp, this light is 5600 or 3200 with a gel. I do like that it dimmable and runs on batteries as well.

We placed three lights along a 7'x3' counter. I am not sure two would be enough. The light is very focused, almost like a task light. The shade is on the small side so it also limits the spread of the light. That being said, I love our grouping of three!

John,I used my light for under the counter task lighting. I don't think it will do the job for a larger area of 25 square feet.

I'm not sure, but it covers a regular circular box that one would use for a ceiling fixture. I used three of these on boxes that were somewhat dated and it worked fine. It is really too far out of reach for me just to go and measure. Regardless, for the price these units cannot be beat. I use CFL flood lights and they work really well.
