128 LED flashlight?

Those flashlights are sooo cheap though, I had one with like 32 LED's and the cheap-o imitation-rubber button stopped working out of no where one night and I haven't been able to fix it since.

What's a regular flashlight usually rated at?

That is a dirty, dirty lie.

You can put all the LEDs you want in there, but it's limited by its batteries. And if it can get 30 hours off 4 AAs as it claims (highly suspect as well), it's not going to be very bright.

I'd say it's probably about as bright as an Inova X5. Edit: No, brighter than that... somewhere between an X5 and a Surefire G2.

For years typical LEDs were under 5000 mcd. In the last two years or so, 10-20k mcd standard LEDs became widely available. Very recently, very high power LEDs became available and they can far surpass that level. It appears that the flashlight is using the standard low power 15k mcd LEDs. So as a very crude estimate, imagine the typical LED and make it 3-5 times brighter. Now place 128 of them together. You'll end up with ~500 times as bright as the LEDs you've seen for years. Thus, that flashlight should be bright enough for most needs.

But as others above have mentioned, there is a lie somewhere on the page. 128 of those LEDs will drain those batteries in a couple hours at full brightness. The only way to make it last that long is to turn the brightness way down.

I don't know if they are lying about the battery life or lying about the brightness.

Yea, probably not as bright as you would think.
 
probably wont take long before it starts to fail, cheap workmanship i bet.
as for the light, its all flood, no throw. not that useful.
 
260 lumens, eh?

Surely it would be easier and cheaper just to use a few high-powered LEDs, instead of 128 standard low-power ones. It's not difficult to get LEDs which are 100 lumens each, and you can get 120 lumens if you try.

That said, if you did connect 2 of those high power LEDs to 4 AA (NIMH) batteries, you'd get about 1.5 hours of light.
