Interesting light.
Nice to see the good heatshedding properties of the S70(S) has been kept and maybe even more inline with the Jax Hunter (the original design that if I understand correctly is a bit better the Thorfire S70(S)
Congrats on starting your Kronos business with a flashlight and not a watch, seems more fitting on BLF, cool.
Too bad you decided to be silent after dropping hint and hint of new lights more then a year ago.
It could have been fun to see this come to life. But lucky us it is mere renders now so there are steps to see after all ;).
Who made these nice renders by the way?
Can you show the driver?
It reads like the normal S70s driver with the sense resistor bypassed mod lots have done to get to around 9A.
Have you tested the new XHP70.2?
XHP70 lights are plenty and from ~$37 a S70S could be bought not long ago. Solder blob is practically free so a modern LED could be a nice justification of the high price (well sure people have no problem with you guys earning money but still almost twice the S70S price is pretty steep) it would also show it is a new light, not something in the works for many many months.
Oh yeah do not place me on the list now.
I am curious about the answers I just posted and can decide to be put on there when they are in.
Dang this topic dropped of the front pages fast, a shame so here you go with a bump
Love the L6 anti roll cutouts smacked on a S70(S)/Jax Hunter head. You guys took the two popular XHP70 lights and used the one with the best cooling properties (good!)
For all the Convoy fans using a clear design feature of the L series, very smart.
I can’t recall what brand uses that diamond tube, something with pineapple in torch name
Clever clever!
I’ve seen thermal imaging tests taken as a light was turned on and in the first seconds as the heat made it’s way through the heat sink. They said the pattern was almost exactly an inversion of the light coming out the front, so if you consider the light out the top as the top half of an X and the heat out from under the emitter as the bottom half of this X, you see where the heat needs to go for fast and immediate dispersal.
Having fins on the head, up by the reflector, is simply not efficient. Sure, eventually those fins will transfer some heat to the surrounding air, but the light has to get saturated first, allowing the emitter to sit in it’s own heat for far too long a period.
Deep fins in the expanding cone of thermal path would be most effective. And yes, if aesthetic fins on the head need to be figured in then the pill and head should ideally be one piece for effective saturation transfer.
The centering ring is almost always made of a plastic material, effectively insulating the heavy aluminum reflector against drawing heat away from the mcpcb or substrate. Would be nice if this large piece of aluminum were to be optimally mated to the head and a copper centering ring used to allow effective contact for thermal expansion into the upper part of the head/reflector to aid the lower heat sink. My 2 cents.
