I wonder what it’s like to hold this light. It looks like it’s head heavy, so you have to grip it in front of the buttons where the cooling fins start to keep it balanced. Is it comfortable to hold in such manner for a long period of time…
I like the heavy block vertical (Fins) heat sink(s) at and below the emitter shelf, having a integral shelf, this should do well to dissipate a substantial amount of heat! Hopefully the inner cavity walls are thick too!
Have you tried to make a Shaved Dome to the XHP70? Should be a really nice thing to ~ double the intensity.
6,5 Amp drained from 4S battery or to the Led ?
If you are still picking emitters I can say without a doubt that if you want to appeal to BLF, try to get your hands on a nice neutral/warm (something in the ~4500k range like the 219’s) HIGH CRI LED.
Either XHP35 or XHP70, they are both offered in High CRI. Throwers in particular lend themselves very well to warmer tints IMHO and high CRI is always good.
Other then that ditto the rest, options are very good. I could very well end up with both an XHP35 and XHP70 version if the price is right.
Not only do I agree with Mr. Ace, this seems to be the current trend as well. Manker is offering models with High CRI neutral white Nichia models, as well as Lumintop with the Tool Ti/Cu, Worm Cu and IYP365 models. Even mainstream Nitecore is offering the new TIP with these emitters… High CRI XHP70 would appeal to many here I think as well…
Specs looks good, amps to the LED, shelf thickness, DTP board are being mentioned which means you guys know your stuff. I’m curious about if you have made other flashlights before, maybe under another brand?
If you go with XHP-70, make sure to use the highest bin, and price it sensibly so it can compete with the Convoy L6.
If you go with XHP35 HI, target at least 450kcd because you’ll have two strong competitors from acebeam and trunite.
