What is the total light output? Needs to be around 500mW
1310582
Tech specs say: 12 joules/ minute. My web search says this = .2 joules/sec = 200mW, treatment cycle = 4 minutes for 48 joules. Hope this helps.

not enough, you need full spectrum light @ 10,000 lumens for 20 to 30 minutes. also the item as shown is sold at Phillips web site for 99.00 I don't know if this is some kind of computer error.

Use small candle light size LED bulbs, you get 60w of light from 15w power, makes it very bright.

you need a studio ligth to have a good ilumination, I use with 400 watts wescott ligth

Couldn't tell you off hand what the wattage compares to. You could probably look it up by lumens at Kovac's website? BUT, I put 3 of these lights hung vertically across a 7 foot vanity. Probably could have gotten by with just two lights but still not TOO bright. My daughter said this was the place to go to pluck her eyebrows :0)

24 watts and 2000 lumens. I grew black pearl peppers from seed and this unit was terrifickeep the light about an inch from the top of the seedlings/plant. If it is too far away then the plants will get leggy.

I don't know the exact lumens, but it seems to be equivalent to a 40 watt bulb however, the is very directional and would probably work for your application.

enough to brighten a dark corner. I'm using a 75w bulb and it gives a nice bright glow to the corner and the light is good enough to read by if you're sitting by it.

It's the total. Here's what the package says: Light Output (Lumens) 830, Watts 14.6, Lumens per Watt (Efficacy) 57. So 14.6 x 57 = 832.20. "Visit www.lightingfacts.com for the Label Reference Guide."

It is pretty low, about 3000 lumens, but will light up an average room with white walls and ceiling. You can find bulbs twice the output but they run pretty hot, sometimes smell and buzz (though the output is adjustable).

look for Buck Block at LED Supply. This big boy will supplement your 36volt supply to provide the constant current drive these LEDs need to stay happy. Be aware you will need a humongous heat-sink or forced air cooling to actually use this. And 8-9000 Lumens is a LOT of light. Most real life applications don't need that much light output. It's a fun toy though :) (Yeah, I bought one!)

I would say they put out about 200w light output had a 300w bulb way brighter would only recommend for a smaller pool like twelve thousand gallons

We used 80% of 3W/cell EPISTAR LED bulbs(not 100% to protect the bulb for long life-span), that's 2.4W each,100pcs should has 240w output power,if you use in 12V the current should be between 20A to 22A,and the lumence should be about 24000LM to 26400LM.

In the range of 1-2 watts per LED. There are calculators online to get an exact number if is important.

You could use any 13W, 120VAC, 60 Hz, 220mA, 900 Lumens standard socket bulb. Multiple manufacturers make this type. Get it on AMAZON !

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.
