Hes thrown a real spanner in the works because i now cannot decide on using an L2 host or a Jax z1 i was sure the jax was going to be the better choice but now im on the fence again
The z1 looked like the perfect host for a CULNM1.TG… but i wasnt sure if the L2 had an advantage in heat sinking? (i think im just looking for a reason to need both)
I had a driver I pulled from a Nightwatch flashlight that is around 4.85-5.0A linear driver, just a bunch of 7135’s. Something like this (I have no experience with this store or product):
I think my signature has a link to some posts about my Z1 build. In general, while it probably doesn’t have as high candela, it is more impressive than my MF02.
Edit: nope, but my post history will. I’m not on a computer right now or I’d find them myself for ya.
Well I ordered a Z1 to host my precious new emitter in received from Led4power today, Really nicely packed an sealed and the reflow looks expertly done!! , I also ordered the Convoy L6 , what can i say… I have a problem and banggood baited me with their 30% off promotion…
Anyway I’ve now read this thread start to finish 3-4 times excellent posts from many of you one thing i would really like to know or see is some kind of chart that references emitter lifespan with amps, I note some of you want reliability and some of you want the fastest standing quarter. it would be nice to have even just some estimates of emitter life vs current
For example (Assuming well mounted in a good thermal host)
at stock 3 amps 10,000 hours
at 4 amps
at 5 amps
at 6 amps
at 7 amps (A few seconds)
Unless i’ve missed it that doesnt seem to be covered on here
You wont find that anywhere. How is anybody supposed to get that data? We are driving these LEDs outside the official specs. Realistically you will never have problems if you don't go right to the edge. The internal temperature of the LED is the important thing here.
I do led testing but not that type and you will never get that data I can tell you. Led failure is a chance proces so the set-up is at least 10 leds per current, so 40 leds for 4 currents, 40 independent current controlled power supply outlets totalling at 800W, continuously burdening my electricity bill for say half a year. And at that is a lifetime measurement on just 1 singel led.
