what is lumen output?

Not sure the lumens. I did have two of these bulbs stop working after only a hundred or so hours. Not recommended.

Maxsa innovations website reports 300 lumens for this model. Great light, nice amount of light output.

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

John - Sorry I can't tell you the lux output. It was advertised as full spectrum light and puts out approx 1400 lumins. Hope that helps.

It has 11 lumens of output, and this is a great flashlight. It is used often by mechanics and it takes a beating. I have had mine for 8 years and it still works great.

The 24 and 48 lumen versions both use the C4 LED the 48 lumen is an upgrade to the C4 LED.Hopefully the package states the output.

A lumen is a quantity of brightness; thus the higher the number of lumens, the brighter the light source.

It's not very bright at all. In fact I was very disappointed with the amount of lumens actually put out. I'm thinking of replacing the two that I purchased because they're just not doing the job.

I do not have actual lumen information, just be aware this is a weak laser and you cannot see it outdoors in daylight at much over 10 feet. The switch on mine is touchy and would turn on light and waste batteries without my involvement, make sure to use the main switch and turn unit off or have a steady supply of batteries.

I just assumed that the 20W was actual power consumption for the LED matrix. You seem to think the 20W is some kind of equivalent light output wattage in incandescent terms.Lumens is light output. If you have the 1600 lumens, you have the light output. 20 watts in, 1600 lumens out. What more do you need?

I don't know the Lumens but it does put out a nice amount of light. It stays lite up all night. Not for flags larger than 3 x 5.

I don't know what the output is, the manufacturer should be able to tell you. However, I will tell you that I've had two to these lights and both failed after roughly 3 months. The first was replaced under warranty. After the second failed I just tossed it and bought something else. The light output was adequate, the fact that two of them had problems had me questioning the quality of the fixture.

Do not know about lumens but the lamp is very good and looks nice. I bought 4 last year...very good.

Sorry, I don't know the lumens, it uses 2) 3volt lithium cells. i only use it for lighting my car locks or my pack to find stuff. the light is flood and not spot so not a huge distance. I use it frequently and have not had to change out the batteries yet, so for my purpose it is worth the cost.

I have no way of testing the actual lumen output, but it is the brightest flashlight I own right now. For the price, I love it. I use it often but not for extended periods. It's really bright even in daylight situations when you need a little extra light. It also seems to be quite reliable; I have dropped it numerous times and it still functions perfectly and I have not had to charge the battery yet so it seems there are no voltage leaks in the circuitry (had it over 1 month now on initial charge). Overall, I believe it is well worth the price.

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.

I don't know what the exact lumen output is, but our basil plant did really well under its light at about 6 to 8 inches away while the glow panel was new. Unfortunately, the life time of this device is not good. The LEDs, especially the blue ones go dim or die outright in less than a year at a usage of about 10 hours a day. After enough LEDs fail, the whole rest of the array no longer lights up at all. I would rate this grow lamp much higher, if the LEDs were individually user replaceable and purchasable at a reasonable price each.
