At first I thought I would like infinite variable output so I purchased the D10. Then I found out I like to know how much runtime on each mode. That's pretty hard to determine on an infinite variable output light. It might look like 20 lumen but it could be 30 lumen because IIRC our eyes can't really tell the difference, but that actually reduces the runtime. So I sold it. I am now only getting preset mode because I know how much runtime I can get per battery on each mode; plus or minus some. THANKS SELFBUILT. It's the comfort of knowing.
Does any one have the condition I have?
- OR -
If you still love infinite variable output, let me know how you determine runtime assuming you don't carry spare because quite frankly I don't carry spares. My job does not require me to carry a light or spares, I just like flashlights. If your method actually works, I might change my view and get another D10.
