How long can the light run in the highest mode, second, and third highest? Before it’s too hot to hold?
Is it something like
1st mode -10 second
2nd - 45 second
3rd - 1.5 minute
Hello no answer…it’s a simple test can you do it right quick
At full blast, 20A, the head is too hot to hold after ~22s
High mode (35%) around 1 Minute
I don’t care about the head, I care about the farthest approximately 3 inches in the back of the flashlight near the tail cap, that’s where I typically hold it.
What about the other settings both turbo, high and medium, how long does the back of the flashlight take to get too hot, can it at least hold the second lowest mode for like 5 minutes without burning my hand
Buy it and check yourself.

Anyone have any issues activating / deactivating mode memory with theirs? Mine will only cycle to the next mode in whichever group I select… Menu option 1 works fine - I can set whichever group I want.
I’m not exactly a noob with Convoy - I know there have been past issues with some drivers - and no amount of half-presses or clicks in the 2nd menu option with change any behavior for me… I’ve cleaned all my contact surfaces, tightened both retaining rings and I’m using a fully-charged Molicel P50b.
Hope it’s not a buggy driver, I would prefer to have it always start on low.
Do you have a lighted switch? Certain color/driver combinations are known to mess with the UI. I don’t have a good guess aside from this.

Nah, just the standard white booted, non-illuminated one - silver body, so it didn’t come with a black boot.
