Id like to see if reaching that number before you buy another light due to better technology or what ever the case may be is likely.
noHas any here hit the 50,000 hour led life span?

The clicky is probably the first flashlight part that will fail (Not counting the battery), but I don't know of a good standardized test that has been done to compare failure rates of the systems in a light. Arguing from first principles and barring unusual events, you'll lose:I worry about how many on/off cycles clicky switches will take.
I think that white LEDs are rated for 50,000 hours down to 50% brightness. They should continue to work after that time, but at still ever decreasing brightness. So at 100,000 hours, you're looking at 25% brightness.
Some of the older hands here might recall reports of the LuxV exhibiting a visible decrease in brightness after as little as 500 hours of use. Apparently those were driven hard enough to get HOT in some lights.
Edit: And if anyone expects 50,000 hours of runtime from LEDs at 'CPF' drive levels, I have a 500,000 hours MTBF (i.e. 57 years) hard drive to sell them.
For upgrades, sure; but not for the LED running out under normal use.I never liked the idea of making the led module not replaceable.
