I think '50 lumens' and 'very bright' seems like an oxymoron. Please clarify.

I don't know where you get 50 lumens from. This light is 600 or better lumens and yes very bright for its size. Thank you chris from RI, very good.....Cliff from Ca.

There are a lot of identical looking flashlights out there but they are NOT the same. Read the specifications carefully. They don't all take the same batteries nor do they all have the same CREE LED. This flashlight, if you get the same one I did, is exceptionally bright. Word has it that sellers are often substituting inferior but identical looking items. The one I got from this seller is absolutely tremendous. This is WAY more than 50 lumens. The light is blinding.

The bulb is "XML". You'll find it's 1000 lumens @ 3W on cree.com by googling "cree XML". 18650's easily supply 3W.

i think you might want to learn what oxymoron means. Where does it say, anywhere, anything about 50 lumens?

I'm not sure whom you are asking this question to? That would be an oxymoron to clarify your English lessons.

Not sure of the reason for the variance. From what I understand, if you use rechargable lithium batteries, you'll achieve maximum lumen output.

You are right the lights are very bright. Mine are behind something so I don't have your problem. I don't think I can improve on the answers from Wally B and Robert C.

This model is 500 lumens. I doubt you would be able to tell the difference between the two different powers.

It's not a matter of brightness. Both emit the same # of lumens. It's a function of the light spectrum they emit. So it's really an aesthetics question. Some people don't care for "white" that's in the 5,000K range and prefer the "warm" or yellowish light emitted at 3500K.

They seem to be all around. I used them for courtesy lamp replacement in my boat. They are so bright that I had to replace them with the original incandescent lights. Whether or not that is a plus, or a minus has to do with application, and preference.

Whoops! Unlike GeorgeM (who really knows his instrumentation), you're confusing colour temperature (5000K, 6000K) with light output (Lumens, spherical candle power). Cheers!

13 lumens sounds about right. I would have guessed less than 50 lumens. This thing is not that bright for using 3 AA batteries. I would rather get a CREE flashlight that uses 1 AA.

I bought the light and it is plenty bright. I think the true output is 520.The spot is very tight ans so using it to walk the dog is iffy. I added a removable diffuser to the lense. Another poing is that to turn it on you turn a knob. (Not what you expect).

I didnt actually measure the lumens,,maybe this genius did,,but i doubt it,,i can tell you my honest opinion,,its brighter by fatr,,than any other light ive found at a bike store,,it very well made,,the beam is adjustable which is a great advantage,,its brighter than the headlight on my daughters moped,,and after i had an issue,,,due to me putting it on a moped with much more vibration than it was made to endure,,,the company came through and handled my complaint better than any other company would have,,,buy the light...

No, mine is 81 lumens but it is the absolute best flashlight I ever owned. Absolute versatility and power. This flashlight seems to have a built in brain and you will soon know what I'm talking about once you start using it. This flashlight could even save your life someday, it's that good. I use it for work, I use it for fishing, I use it when fixing my car, I use it when I walk at night, just carry it with you everyday and you will find out that it paid for itself in no time. Uses rechargeable batteries flawlessly.

The info. I got was 500. I have no way of testing it. At 500 or 600 its still super bright. I saw a test where it beat a 800 lumen light.

I would say that the light output is fairly impressive. To me the lumen output is around 60 lumens but its a fairly wide beam. The beam pattern is somewhere in the range of 160 degrees as it spreads out pretty fair. Ay other questions just ask.

Mine works great for any situation. I would do 250 lumen. The more light, the better traffic will be able to see you.

I received two XL50s with my order. One was labeled 139 lumens and the other 200 lumens. Otherwise, the packaging and flashlights are identical. I can detect no differences in brightness between the two. They are very bright. Unsure why varying lumens are listed among different website descriptions for the XL50. Mine appear to be identical.

I believe that has to be a misprint. A 100 watt bulb would be too bright as well as too hot. I have a 13 watt fluorescent bulb in mine that is equivalent to the light output of a 60 watt incandescent bulb. If you chose to go with an incandescent bulb. I would not go higher that 40 watts.

According to most conversion charts I've seen, 1600 lumens is roughly equivalent to a 100 watt bulb. However as others have responded, this light does seem brighter to me - part of that may be that it is rated at a Color Temperature 4000 Kelvin which is a fairly bright white (but not quite daylight) fixture. If you remove the diffuser and look at it while it's on, it's extremely bright. Look at it while it's off and it is very geeky nerdy interesting! :)
