Great answer Jason. I guess I was thinking one of the maths wizzes would be able to do an estimate runtime - I was amaze someone way able to assess the max kcd based on the head size? Must be some crazy parabolic analysis haha
Assuming the internal mass of this light is the same as a C8, then we can ask someone with a C8 that has a fet driver running an xpl or xm-l2 at about 4.5A what kind of runtimes they get on turbo.
A stock C8 has a 2.8A draw and turbo does not effect it greatly. That’s just 10 watts.
The mini GT should be around 18 watts. Maybe someone can chime in about the thermal limits.
I think the reflector size is also about C8 sized and just as before, I’m sure there are people running xpl-hi emitters in them that can give us a close approximation of the candela.
So there’s no real math involved, just comparisons to similar lights.
Emisar D1S has “RampingIOS” UI, sometimes called the Emisar D4 UI. It is based off NarsilM, but Emisar owner Hank wanted some changes to make it unique. If you like one, you’ll like the other.
I think they will be very similar in performance. Both have 50mm head, same weight, same emitter, similar brightness, similar price, etc… We still don’t know what driver the mini GT will use. It’s to be determined.
In my opinion, the big difference between it and the D1S is styling.
There’s much more to a reflector than it’s diameter, depth also determines efficiency not to mention the coating quality and the nature of the emitter opening in conjunction with the centering ring and factory acquired focus… and of course the lens quality also greatly influences out the front lumens production.
One can always assume whatever they wish, without actually measuring a production light it’s just going to be impossible to know… (even then the measurement results will be hotly debated. )
Madmax showed “measured 145000 cd (@3m compared to C8s / acebeam L16 / Imalent RT35 / Emisar D1)” on post #2.
I take these measurements with a grain of salt. It’s in the same ballpark as the D1S, so I would say they are equivalent. It may not match exactly to those other lights, but I doubt our eyes will see a difference.
Any word on how it’s going to ship? On the GT I had to pay 40$ for DHL and now I’m having troubles with my customs. It has been stuck at the customs 60miles from me for 2 weeks now.
Filled out the form, it’s a thrower so it’s gotta be a CW version
Legit question from a non modder: why not use a boost driver and put in a XHP35? Is the emitter too big for that reflector and it won’t be a thrower anymore? Or would heat be the issue?
There’s already 3 or 4 lights like that. The price would go up probably 50% or more. I don’t even think Thorfire has a boost driver that can do 30w. I’m not even sure they can build boost drivers, much less one as powerful as they need to exceed this xpl’s output. These are all my guesses.
