For now I have lost interest in this light and it is on the shelf until work is done on it.
I hike every night with my friend Randy and his Dog Max. Randy and I both love Turbo when on the hiking trails. I get enjoyment for 2 minutes of Turbo and then it is constantly stepping back up to Turbo every 60 to 90 seconds.It becomes Very annoying.
My Mateminco MT35[FT03] XHP50.2 NW has Narsil. I disabled the step down. The light never got too hot even in August.
When my NI40 is able to do that, I will enjoy it more than the MT35 because I like all the other aspects of the light.
I had filled out the form and submitted it, expected a notification when the lights would be ready again. Never happened, which is ok because I too have had so much problem with Neal getting it done that I no longer care to make a purchase if he’s involved. Sad but true.
So I’ll be looking for the 90.2 and will build my own Stalker if/when I find the emitter. In the meantime, the one I have here works pretty well with the original SBT-90. (built a driver for it, hated the UI)
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.
