Surefire L4 Digital Lumamax--Life Expectancy?

Is the MTBF still < 1,000 hours for the 5W LS they use? How hard is it driven?

I don't see a Surefire forum!

Cheers!

The LED is presumably a "portable LED" with the 1K half life. The L4 drives the Luxeon at around 640 mA as I recall, so it is a bit under spec.

PS. SF forum? That's been gone for some time??!?!?

Please do not discuss having a SureFire Forum here.

Thanks treek13.

Back on the topic of "Surefire L4 Digital Lumamax--Life Expectancy?" from here on please.

If I'm not mistaken if it fails Surefire will replace it or fix it. That would mean it should be around for a while.

TO my info, LumiLeds has fixed the problem with white 5 watters, and those used in the L4 have a MTBF of 50K hrs.

Anyone else with info on this?? 50K hours would mean that maybe, maybe, my son will have to worry about changing the LED in the ole' L4 after he inherits it from me!

I have just seen the TL-3 (Streamlight) with the 5 W white LED, advertised for 10K hrs of life. (on Meridian Tactical and others)

Why SF should have put a "portable LED" in my beloved L4? Lumileds announced "stable" white 5 watters for 2003 third quarter, but I think they were available to OEM sometime earlier.

lifetime warranty !! =)

50k hours? Bummer. I'm hoping to have mine die in about a year so I can get it replaced when Z3T bins are common, hehe.

50k hours? WOW, Is this for real????????

>>Do not start another thread on this and do not ask about it again. Yes, this is a VERY sore subject.

Yep, that's our full-of-info FAQ alright. Long on complaints/threats, short on explanations. Like, it'd be so hard for a moderator to just ignore sore subjects... But, no SysOp is perfect so I guess I'll take what we can get.

Hey, not that I care, I can't afford SF anyway. Heh. Well, not if I keep sending $$ to EL and Inretech. I'll look forward to a "new improved" 5W when/if the 1000 hr. one in my Blaster IV ever craps out.

I think were I to get another 5W, the Streamlight 3x123 driven 5W would appeal more than the shorter runtime on the L4, but the size diff. would make it tough to decide. I sure wish they'd re-tool the L4 so it doesn't look like such an E2e with a frankenstein head, though.

Beauty is in the eye of the beholder! I think my L4 is purdy. /ubbthreads/images/graemlins/grin.gif

To each his own, of course. Personally, the SF that appeals to me most (in profile) is the A2. Perhaps because they can't seem to make enough of them, though, the price is insane. If only the L4 had 2 or 3 brightness levels it would replace the A2...and extend the life of its poor ol' LED while it was at it.

I have ordered a KL-1 head since my KL-4 head on my L4 doesn't have a "volume control" That way, if I need less light for a longer time, I can just switch heads.

I wish they'd make a very tight focused version of the KL-4, though.
