9 reasons to buy

Experts consider the BC21R V3.0 well-made.

Testers and owners find the mount easy to install.

This light has a replaceable battery, but Fenix recommends only using the spares it sells.

A long-term owner uses the same battery for several years before replacing it.

The BC21R V3.0 can be used in low and medium modes while charging.

Fenix provides a useful graph that demonstrates run times and lumen output in each mode.

This light is waterproof.

The BC21R V3.0 can be used as a helmet light, though the helmet mount costs extra.

Fenix offers an optional adapter for GoPro mounts.

4 reasons not to buy

One expert complains that the washers on the mount loosen after a week of use. A buyer also says the mount loosens with use.

The BC21R V3.0 doesn’t offer any side-on visibility.

The light's narrow beam means it's insufficient as a standalone light for trail riding

The high-low flash pattern uses battery faster than an on-off pattern.

Bottom line

Fenix’s BC21R V3.0 is a 1200-lumen front light with five modes, including flash. It has a proprietary mount that fits handlebar diameters from 28mm to 35mm. A helmet mount and GoPro mount adapter are available separately. Testers and owners praise its durability, the easy-to-install mount, and the swappable battery. The light is deemed suitable as a secondary light for trail riding, for road or commuter use, or as a helmet light. Complaints are few, but the loosening mount and lack of side-on visibility frustrate some users. Overall, the Fenix BC21R V3.0 is deemed good value, especially given its high lumen output.
