My Surefire L5 becomes dimmer, is it normal?

If you can quantify "dimmer", it would be of great help. Lux V do not have good lumen maintenance unlike the single die Luxeons. Depending on how long and how often you've used it (and if it gets used at high ambient temps) then it's possible the LED is going through its normal lumen depreciation. But since you mention it doesn't get hot, there could also be some problem with the driver. You need to give more details.

Don't worry about the life of the lux V, I used my L5 for 3 years, every night for over an hours and it's still bright and hot like new, except the clicky, change it 3 times.
You need to change battery and clean the thread, that all. If still not bright, change the clicky.

Is that the Z58 clickie? Is this clickie really that bad?
BTW I heard the Z48 is a much better clickie with fewer problems, is that true?

The Z48/Z49/SW02 Clickies are significantly more robust (and larger as a result).
regarding the L5, if it's not the batteries then the KL5 bezel could be faulty - in which case I suggest you call SureFire.

Oh man, don't tell me this stuff. I just got an L5! Auughh
nuw040,
If you have a pair of those solar eclipse gogles or welding glasses, try to look through them directly at the Luxeon (*DON'T* do it with your naked eye
). You should see 4 seperate squares lighting up with equal brightness (Where is that picture?). If one or more of the dies are dimmer than the rest, you've got a faulty Lux V on your hands.
KDOG3,
The L5 is very reliable, and very few defects have been reported here on CPF - Don't worry.

have you bought a EVEN brighter light recently?
it may cause your mind to think that your L5 is dim.

Thank You everybody.
I cleaned the clickie by using electronic conductor cleaner (The red pointed area). And it work very well right now.
Please see the photo about the parts inside a clickie.
