It seems to me when the temperature of the environment is 25°C and the temperature control of 55°C the D18 will be thermostable at 1500Lm. For greater brightness without overheating in such the body D18, emitters are needed XHP.
Turbo mode (14000Lm) will be very short, about 80 seconds.
I’m surprised to see that nobody asks about what optics the D18 use.
Ok, I can not wait to tell you, that in order to maintain a smaller head, and as pocket-able as possible,
we use 18 pcs single optics, and squeeze every tiny room in the head. Not a easy work for the assembly, the production speed is slow.
With a “normal” driver and the best firmware around. Glad to see you got your hands in this one TK, I remember you aching when you couldnt do anything with the Meteor FW.
PS: This has a bit of a DBCustom vibe coming from it haha.
Will this dethrone my ROT66? No stainless steel tailcap, aux leds on button and head are turndowns compared to the ROT66, but the sheer turbo burst output and the possibility of more efficient lower runtimes make me salivate. If 9 emitters in an ROT66 can run without heat at around 1400 lumens, I’m assuming double the emitters can get up to like 2-2500 lumens without heat issues? Maybe, but it is a small host.
