Re: HOLY THREAD JACK
P60L ~ 50,000 hours. So, it'll probably get destroyed, or you'll be dead, before it burns out.
The newer one's use the KX4, where the "module/emitter" is "sealed" in the head. This is essentially what WAS going to be the P61L, but the drop-in couldn't handle the heat, so they built the head around the module, giving it better thermal management properties. Most LED's are properly managed in the light design, and will last "forever" as far as you should be concerned. Some of the older LED's had 10,000 hours life spans, but, again, that YEARS of continous use, so it's really a mute point, until you get into custom, over driven emitters. Some mfg's that over drive the emitters will have shorter life spans, but since all this LED stuff is relatively new, no has had the chance to find out. The old Lux-V emitters on the older Sure L4's have been known to "die", where they lose about half there out-put, but this is after several years of hours of use a day. These Lux-V's were being driven near there max though.
