It’ll be more complicated than that because at some point the voltage will drop below the threshold required to maintain the 4.5A current draw. At that point, brightness will start decreasing, but so will current draw.
End result is the total runtime will be longer than 40 minutes, but the runtime at max brightness will be less.
No, that’s something Lumintop would have to tell us. They could design the driver to fall out of regulation at different voltages. They might not tell us, but we could still measure it once we get the lights.
Like Delta_V said, it’s more complicated than that. Keep in mind that in the real world thermal protection may activate. So you would measure on high, then turn off and cool down the light, then run on high again, then add up all the run times to find out the total run time on high (within regulation). Is that what you meant? Or did you mean how long it will it run before stepping down due to heat?
I can only say that you will definitely get longer, steadier run times at 3.5A. Also, a high drain battery will stay in regulation longer in comparison to a high capacity battery.
We won’t get any real runtime data until the light gets tested.
all people who already placed their preorders can add a new order until monday morning (beijing time)
then it should be shipped with the GT Mini!
news #2: Lumintop wants to thank the GT Mini buyers and offered me some gifts to share:
5% of the placed orders will get a free flashlight (shipped by amazon)
for winners in the US, Canada and Mexico: (click the pic)
for winners in europe: (click the pic)
RULES:
every 100 orders for GT Mini flashlights I can choose 5 winners
all orders until July, 22nd 2018 will participate
PREORDER BONUS: 40% of the prices will be drawn from the preorders 60% of the prices will be drawn from all orders
i will make a live video on July 23rd to draw and announce the winners
changes of the rules may occur anytime!
for excample:
634 total orders placed ~ 6×100 -> 5% = 30 gifts
468 preorders participate in the draw of the first 12 gifts (40%)
634 total orders participate in the draw of the next 18 gifts (60%)
news #3: public sales start tuesday, July 17th
i will remove the password of the ordering page on tuesday allowing everyone to buy a Lumintop GT Mini.
