How many lumens??? How can anyone know how this compares with anything that gives off light without a standard? Why is this not the first thing stated

The switch is junk to start with,as far as brightness it's not real bright.

I too have 2 extra lights, the ones with 12 led bulbs. I used 2 for the license plate lights, 1 for cargo area, 1 for globe light, and 2 map lights. Very bright, makes finding things in your truck at night a thing of the past. I noticed that the rear globe light has a very small amount of light coming off it when the vehicle is off; any ideas? I've had them in my xterra now for about 1 year, still going strong.

Lumens are difficult to calculate, since it varies with distance and depends on the actual size and focus of the light. I can tell you that on a fresh pair of batteries, it can light up an average room quite well. It's about as bright as a small Surefire flashlight, or a large incandescent Maglight.

It should be noted that "lumen" can mean many things depending on how you obtain a lumen measurement. At one foot away with the "zoom" at max spread the light produced 4800~4900 lux which is about 450 lumens/sq ft. Though when focus to a point the light produced over 90,000 lux which is about 8,300 lumens/sq ft. Unless you can find definitive data that explains the lumen of this light (or any other light in existence) the advertised brightness of a flashlight is meaningless. It's would be better to look up the datasheet for the Cree XML emitter and search for visual examples of the light (using quality 3.7V 18650 Li-Ion bats of course).

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 about lumens exactly, but I measured the output with a light meter and it registers about 15k to 20k lux (1 lux is equal to 1 lumen per square meter, I think). They say 20k lux is legit for growing plants. I ordered 4 different types of grow lights, and this actually has the highest output (including a 60 dollar T5 setup), it just doesn't cover a whole lot of area, although definitely covers more than the other under $20 LED lights. I may buy quite a few of these.

Unfortunately I do not know the answer to this question. And I would add that the light was not as expected product., I thought I would have more light.No part of this product, lumens is not much explanation.

I am honestly not sure about the lumens. It is a good keychain light and serves it purpose well for what it is.

I am not sure what lumens it puts out other then. I put it in my 74 dodge truck and its like daylight when i turn this light on. Hope this helps

I have checked the box, the instructions and the manufacturer's stamps on the product and I can't find any indication of the lumens/wattage. The light is a 5" LED strip and not one bulb, for example, the type used for nightlights. I was going to add a photo of the light to the product's original description but this is not an option.

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 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.

Yea no problem Cameron, it's not 200 Lumens , it's 125 lumens. Good light for the money

I don't know what lumens are, but it gives outnext to nothing in light. If you expect to see by this light, don't buy it.

I don't have a way to measure lumens. This light casts a wide beam with spot light in center. I would estimate between 400-500 lumens on high setting. For cost and how long batteries last. Light is well worth asking price.

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
