How many lumens is this light?

Lumens are not an appropriate measure of light for an LED grow light. Lumens measure the intensity of light across the entire spectrum of light and not just the amount of light that is photosynthetically active. Only a fraction of the light spectrum is absorbed by plants and used for photosynthesis (primarily in the blue and red spectrum. Plants appear green because most of the green light is reflected and not used for photosynthesis. The LED grow lights are designed to emit only photosynthetically active wavelengths of light. Fluorescent lights give off a much wider spectrum of light and particularly in wavelengths that the human eye can see (greens and yellows) but which are of no use to plants. To compare the effectiveness of a grow light to another light source, one needs to measure the photosynthetically active radiation from each source. However this is a standard not yet adopted by the industry. Thus it is very misleading to use lumens to compare the light output of a narrow spectrum light (LED) with a wide spectrum light source such as a fluorescent light when the useful light is only due to the narrow spectrum. The bottom line is that the Apollo light will support good growth of plants (vegetative and flowering) in a 2-3 square foot growing area when placed about 12-18 inches above the plant. Choose the 180 watt model over the 135 watt if your budget allows.

It is 240 lumens for the white spotlight. There is also a second setting which instead lights the small LEDs which produces 10.8 lumens of light. These two settings are described. The battery length is many times longer when using the lower light LEDs compared to the bright spotlight.

Sorry, don't have a means to measure the lumens. I've verified that it works but purchased it to use in a new house that isn't yet finished.

Its either 130 or 180 lumens. Its very bright and you can focus in the beam.

I do not know the lumens value. But it is bright for the energy it uses. I would say it is equivalent to a 40 watt incadescent light bulb

The latest model is 130 Lumen. I also have one that is 2 years old and that one is 90 lumen.

well, I am not sure exact amount of lumens. But, there are 4 different types of brightness controller so you may like it.I really like this.

Its bright enough to read by, I'm not sure of the # of lumens, it gave off enough light for the room. I had it going for approximately 2 hrs on a full charge when I shut it off, so I cannot tell you how long it would run.

It is fairly bright I'd estimate 40W or 60W equivalent. The light is not as warm as I was hoping for though. It is more daylight than warm.

Sorry I have no way of measuring the lumens, but it is very bright at focal point, hurts the eyes if stared directly even from 5 feet away. I'm happy with the brightness. The only thing is it's small

I don't recall seeing a lumens rating but this is my third led light and it's one of the brightest I have bought so far and love it.

It is not 1000 lumens. I would guess it was around 200-250, but I don't know for sure. However, I did not return it, even though I probably should/could have.

I don't know the lumens. It is more than bright enough to light up the interior of a large cabinet. We have had it over one hear and have not yet replaced the original batteries. It's a good unit.

I cant really tell you how many lumens because i dont really know. But it's super bright. You really can't go wrong for the amount of light you get for under $10. You can just use the basic double AA wich makes it a huge plus for me.

From Planet Bike website, this is 21 lumens. http://ecom1.planetbike.com/3029.html

I have no way of testing the actual lumens but it is the second brightest light I have next to my nitecore mh25. It is plenty bright and it will run for about 2 hours on high.

I'm not sure how many lumens they are but I like the brightness. there are 4 LED lights in each one.
