Inspired by the how many BLF users to change a lightbulb thread, since our LEDs are supposed to last anywhere from 25,000-100,000 hours how many do you have on your most used LED chip (light)
Mine is probably 1000-2000 hours in a bit over a year on a Convoy S2, i have used it for so many renovation projects and cleanups that i was going through 2 fully charged batteries a day on medium for 3 months, plus hundreds of battery charges elsewhere
I've got two 4 month old HD2011s that have probably around ~350 or so power-on hours since I use them on my bike everyday for commuting and other night rides (notably bike party).
I know that when the same question is posed for bicycles while there are lots of types of bikes folks have, the types of bikes that regularly get ridden gravitate around a spec that is begins to define usable practicality.
While it is fun to have big exotic lights (like a 6 x 18650, 3 x MT-G2) I bet the most hours per capita is using a much more “usable” design.
I thought it funny when I ran across a quote from someone who was saying “bla bla bla not like the big C8 lights”. And here I though a C8 was on the small end and personally really like the sweet spot of a 2 cell MT-G2 type light as an answer to the “golden mean”.
Well over 1000 hrs on an SRK. It was opened up so much that I completely wore out the threads on the battery tube and have to hold it together with screws. A few mods later and now it runs at 12+ amps and gets heavy use on my bicycle while powered by a 20 x 18650 parallel pack.
Wow, thats quite the pack, and i am finding the same thing on my starry light, its been opened maybe 150 times and the threads are getting looser
My most used light would be a $12.00 XML-U2 head lamp with about 900 hours on it. I grab a different handheld light everytime I need one so none of them even come close.
Look at everyone with their heavy use of lights
And I’m just here barely reaching 100 hour on any light I own before I bought a new one.
I’m guessing max 80 hours on my seraph sp6 clone for brief unexpected night walks
based on 2 recharges a week at 2 hours runtime after 4 years.
its a k2tffc in a arc ls.
On my three Arc LSs; for years I used all three evenings on camping trips.
My zebralight H52w probably has around 900-1100 hours on it on high plus around another 200-300 hours on low/medium modes plus I got it used from toykeeper (tho I dont think she had it very long before trading it to me for my polished SC52) so in total let’s say it’s got 1300 hours on it.
My most used LED however is a fixture I converted with nichia 119’s, it probably has around 24000 hours on it (that’s ~3 years of constant run time), it almost never get’s shut off.
Well, I have some LED (Sylvania PAR20) light bulbs with over 35,000 hours on them (24/7/365.25 for over four years). I have not measured the output in a while, but don’t notice any falloff in their output.
There are also 6 candelabra style bulbs near the gates to my front porch. They are on sensors and have run an average of 12 hours a day for over 4 years). They are cheap-ish Chinese bulbs, but fairly decent quality. I have had to replace a couple of them due to driver failures. The original bulbs were 40-60 watt incandescents. The LEDs are like 2-3 watts. They have paid for themselves many times over.
very impressive, i had some CFLs with about 14000 hours on them (6000 hour rated) when i moved out but i would think Sylvania should be interested in your Par20s
I remember toyota being interested in a Prius taxi with 600k on it a while back, i wonder what they learned from tearing it down.

I think that Sylvania only warranted those PAR20’s for 25,000 hours.
Of the 300+ LED bulbs in my house I have had to replace maybe 5 of them… all infant mortality cases covered under warranty. Two of the failed bulbs were from the batches that Lighting Science Group recalled. The only failure in the last year or so was one of those Chinese candelabra bulbs on the front porch. When I was using halogens, I was replacing at least one bulb a week.
I remember reading your thread, lots of adventure
I have mostly LED around here, except for (3) 23W CFL, i hope they last another year or two and LED equivalents get a lot cheaper, i especially like the LED in the basement and washroom, where CFLs last a few months to a year, i’ve needed no LED replacements so far and they come with 3 and 5 year warranties (and cost $6 or less each with tax, the best came in at $1.22 tax in on clearance).
I bought most of my bulbs from a place on Ebay that appears to sell a lot of Home Depot returned items. I paid less for most of them than the halogens were costing.
I did pay good money for some new 95 CRI PAR20s, some 10W PAR16’s, and some 490 lumen Philips MR16’s. Even with those special bulbs, considering the halogen bulb/blown dimmer replacement costs and electricity savings I figure I passed the payback point over a year ago.
At the time I went all LED, without those cheap bulbs from Ebay I figured it would have cost around $14,000 dollars to do the LED retrofit. LED PAR20s and PAR38s were retailing for $40-$70 bucks a pop at the time. They are a little cheaper now… :party:
Just a little, 60W equivalents can be had for well under $5. Mine are all phillips, from home depot and Tractor Supply Company
