Realistically run times will be longer as the light will quit pulling those listed current draws as the cell dies which will put the run time on a curve in the end.
I’ve wondered for a long time about absolute run time even on a constant current driver, because as the cell dies the driver will pull on it harder to maintain the set current and make the cell die even faster, so the tail amp draw goes up as the cell’s voltage goes down, would a 5000mAh cell deliver one hour of run time at 5A constant current? Don’t know that I’ve seen anyone chart that kind of driver out for provenance. (they probably have, I just don’t remember)
I ran my L6 on the highest setting for over a half hour sitting on my bench with no cooling. It was pretty warm but still easy to hold and it didnt step down. I had done the spring bypass but no mod otherwise.
I have also tryied run mine on highest for a long time, yes it gets warm but no way near that hot as the emisar d4 for example gets and its impossible hold without almost burning, but ofc i would never leave the light on highest unattended and go away. I was kinda scared before i got mine how people said here it quickly gets hot, thats not true at all the head is quite big and manages the heat very good if uask me and having it on for a long time doesnt feel like its an issue with heat really.
You were probably reading about the highly modded L6’s. Simon has run tests of letting the stock light run on turbo for an hour with no air circulation. It gets really hot, about 60° C IIRC, but levels out then starts to run cooler as the batteries drain.
On my light doing 17A, it’s a different situation. It would burn you after 2 minutes. I dont even let it get that hot. Maybe 30 seconds on turbo at most (with fresh batteries).
actually it said on gearbest specs where i bought it from that it can reach 80-90c on highest if left for too long i guess a silly typo?… but yea ok modded i can understand its a different story JasonWW.
It might have been 80° to 90°. It’s been a long time since I read this. It was hot enough to burn you. But it’s also a worse case scenario, because the act of holding it wicks away some heat and any type of air current also helps to keep the temperature under control.
Ps, I’m a °F user, not a °C user, so it’s hard for me to relate to Celsius numbers. :disappointed:
well the l6 has a bigger heatsink and head so that shouldnt be a suprise, also a lot more compact, they both are great lights tho but yeah it would be ideal if the q8 could handle heat like the l6…. lumens and heat isnt easy to solve.
