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
Pros
- Affordable
- Produces a lot of light
- Easily replaceable standard 21700 battery
- USB-C charging port
- Can be charged while in use
- Neutral white light (around 4000K) for better contrast in natural environments
- Maintains brightness more consistently over time compared to SOF BS01
- Higher efficiency (extracts more light from the same battery capacity)
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
- Not STVZO-approved
- Boost mode (highest brightness) only lasts a few minutes
- In newer versions, the control is less intuitive (long press to cycle brightness, short press to turn off, which can accidentally turn off the light during riding)
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
- 210m distance (manufacturer claim)
- Anti-glare design with a clear cut-off, but not STVZO-approved
- Neutral white light color (around 4000K)
- Boost mode activated by double-click, not included in normal brightness cycling
- Mounting system allows rotation for alignment but is less convenient than a standard Garmin mount
