Finally, batteries all charged. What a light. Besides the intense hot spot, it has a nice spill, much more than the original. I also did a side by side comparison between the GT70 and MF04S. Both are NW. Lights are very similar in the size of spot and flood they throw, but the GT7 with 1500+ more lumen definitely dominates. :-)
Sheesh. Just finished charging all the batteries. And that’s with all 8 charging at once lol. Ok so I turbo’d it to a structure about 250 yards away. It doesn’t light it up like I had imagined. The beam is nice and wide but I want more throw and am willing to sacrifice the spill. Do I slice off the dome?
Maybe I should order a new LED/MCPCB to slice off the dome haha. Thanks guys. Loving it so far. This is so ridiculously large and heavy that I’m forced to use an air cushioned shoulder strap from a Nanuk case. The one that it came with is awful lol. Btw, it fits perfectly in a HF Apache 3800 hardcase with room for extra battery carriers and other small lights. $32 with a coupon.
If you add up 8 x 30Q you get 6 amp hours at “12v”. On turbo it draws about 7A to 8A. If it could sustain 8A then you’d get 45 minutes of run time, but it can’t sustain that due to heat as well as voltage drop. As the voltage drops your amperage drops which extends the run time. So I think turbo would be at least an hour, not counting the cool down periods. This is just an estimation. I’m not sure when the LVP would kick in and force it to run at a lower level which would then extend run times further.
In the original GT it could be set to the 2A level and give about 2H 50 minutes with 8 x 30Q until lvp kicks in, but it would be drawing less than 2A near the end due to low voltage.
Yeah I can’t see having the light on at full brightness for more than minutes at a time so this light can easily last me through my outings (multiple ones even) and just charge the batteries when I get home.
I don’t know about that haha. I took my OG GT out camping with my buddy and we went out to the water at 2am and must have had that thing on turbo for an hour straight. That’s the first time I ever noticed it getting slightly warm to the touch and hearing the joints tink and pop lol. It was slightly hazy out and the effect on the water, trees, and clouds was just amazing.
