Reviews & Ratings
The reviewer compares the Lumintop B01 flashlight to the SOF BS01 and Busch & Müller Core 2. He notes the Lumintop B01 is affordable, produces a lot of light, has a Type-C charging port, and features an easily replaceable standard 21700 battery. However, it lacks proper battery level indication, has a less convenient mounting system, and its light distribution has some deficits. The light color is neutral white (around 4000K), and it maintains brightness more consistently than the SOF BS01, though its highest brightness (boost mode) only lasts a few minutes. It is not STVZO-approved, and its brightest spot in the beam is relatively low, affecting long-distance visibility when adjusted to be glare-free.
AI Summary

Cons
- Deficits in light distribution
- No proper battery level indicator (only a blinking green light when almost empty)
- Less convenient mounting system (requires proper orientation and adjustment)
- Brightest spot in the beam is relatively low, reducing long-distance visibility when adjusted to be glare-free

Key Points
- Type-C rechargeable
- Uses standard 21700 lithium-ion battery (5000 mAh)
- 850 lumens (manufacturer claim), but measured around 1400 lumens in boost mode initially
