Ran it 10 minutes on turbo tonight, changed battery and repeated.Not even close to hot. Temperature was 25F/-4C.
In the warm weather I can do the same. I have a high tolerance to heat. With this light by the time I pass the 5 or 6 minute mark the battery is certainly weakening along with the output, resulting in less heat.
I do not know. I do not know how to work on these lights like a lot of you. A member on here is going to make positive changes for me. Completely eliminating step down,new driver, bypass springs ect.
I have 2 orders from Neal but since it was out of stock I asked if he can replace it with one Acebeam K30GT since I can’t wait anymore. He agreed and I received it in 3 days… Also uses the same LED, SBT90.2
The K30-GT is a MUCH better light than the NI40 SBT90.2. While the NI40 has a great host design for heat shedding, the driver sucks with an agressive step down. Also driver efficiency is nowhere near as efficient as Acebeam driver. Though I don’t have the K30-GT, I have many other Acebeam lights and I can say their driver efficiency and regulation is much better than any of the budget brands making them more practical for use as tools.
I agree. This one throws further and has more output compared to both FT03 SST40 and XHP50 that I have even with a smaller head. Step down is not agressive as the light will get so hot to touch within a few minutes of turbo. I might still get the NI40 SBT90.2 version if the stock issue has been sorted out.
The driver does suck! Like they say, you get what you pay for. In all fairness it is less than half the price of the K30-GT. Like I said a few days ago, it is on the shelf until it gets re worked.
