How many lumens of light does an individual unit produce?

There is no information on the package regarding the lumens, but their website might provide an answer to your question. Per the package- maxximastyle.com

at full brightness they travel a decent ammount, I see a faint shadow of myself on the wall opposite of the light about 8 feet away

Enough that I can see a faint glow from my bathroom 20 feet away but not enough to interfere with my sleeping. Enough to light the four steps on my stairs but not so much that I don't still pull out my phone to amplify what I can see while walking up them at night.

I don't know the lumen output, but the light is for effect only. It is very low light. Also, the batteries do not last more than one season without replacement. I have had these 3 years and that is my main issue.

lumens are not written on pack. But based on general formula it is around 3000 lumens.You can find formula here ..http://www.efi.org/factoids/lumens.html and http://lumennow.org/lumens-vs-watts/

42 Lumens. Its quite bright. Meaning, don't stare directly into it (unless you enjoy going blind) - kind of like the sun except smaller. Technology is amazing, this includes the internet.. love your work Mr. Draper.

The lumen output goes up very slightly as voltage rises due to the regulation not being perfect, but the difference is so small that most peoples' eyes could not discern the difference. Lumen output is roughly 1200 to 1500 lumens, it is hard to compare since the beam is so floody but this is what the component datasheet suggests at the measured drive current.

Don't know, sorry, but it does only have one intensity, not variable in my lamp.

The manual that comes with it does not say. Nor is that info on their website. However I have bought 3 other brands which do list the amount of light they produce so I can make a comparison of sorts. It it at least as bright as the light that claims 10 lumens (maybe brighter) but it is Not as bright as the one that claims 40 lumens. So somewhere in the 10-20 lumen range I think.

I am not sure. However, the light appears to put out that much light. It is very bright. So far, the output seems to be appropriate for the claimed amount. My reason is that it compares favorably with a hand held flashlight that puts out 300 lumens. I have several with various outputs. This light is very effective for camping and for emergency lighting.

With one plant growing, you can put the light anywhere from 1ft., up to 5ft. The closer the light the thicker the bush. Led's won't burn your plant. The lumens are another story. Some blubs produce 30/40lm. Others, the new generation can put out up to 100lm or more according to the data I've read. Might to check with vm innovations. Happy growing! Mike.

Their claims seem a bit off, it's more like 1200 to 1500 lumens. Elsewhere datasheets show 67 lumens per watt Epistar LEDs and current measurements show 23W INPUT, so you do the math subtracting for inefficiencies since output must be lower than input power. It's still a good lumen:price ratio but the actual lumen range is helpful to know for comparative purposes.

I wouldn't worry about the Lumens. I returned them because out of the whole box only one worked. I wouldn't recommend them.

both comments below are wrong, the lumens would be 95,000. given the info from the ushio website you can do the math {95,000(lux)x0.0122(hps[source])=1,159(par)}. the website says 1,150 par so you can do the math backwards to figure out the lumens. this can be done for mh bulbs too by substituting the source to (0.0141). regardless this is a badass bulb that pumps out 7,000 more lumens than the standard hps bulb! hope this helps!

Sorry I can not answer that question at this time - last week I sent both units back for an exchange because both have failed. They should be here sometime next week and I will let you know when I look at the light's information at that time.

Amanda, I know that it provides 3780 lumens, however, I do not have any photometric information at this time. That factory is in the process of moving, but if I can get anything further from them I will get back to you. Sorry -- Barry

I don't know how many lumens. You can definitely see the difference though. I am so glad I bought them.

According to the Wikipedia entry on 'Incandescent light bulb': "The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared to the 60 lm/W of a compact fluorescent bulb." That would mean 20 lumens is about the same as a 1.25 watt incandescent bulb -- slightly less than 1/3 the light of a 4watt small incandescent nightlight. That's the theory anyway...
