– Front light: replaceable 21700 battery (18 Wh) with up to 2,500 lumens (high output) but limited runtime and heat; multiple modes from 50 to 1,400 lumens, with longer runtimes (up to 52 hours) at lower outputs.
– Rear light: built-in ~1.5 Wh battery (400 mAh), steady runtimes up to 6 hours; need flashing mode to reach mid-range runtimes (up to 15 hours).
– Pairing and sharing: lights can be paired to turn on together; rear light adjustable from front light within about 5 feet; battery level indicator only on the front light; both can be charged while in use.
– Design and availability: IP66 water resistance, some impact resistance, compatible with ALD-10 Quick Release Bike Mount; introductory US price around $130 (later around $170).
Fenix has introduced the BC28R light set. It consists of two lights designed specifically for use on bicycles. The set is IP66-rated, meaning it can be used in heavy rain according to the manufacturer, and it is also said to withstand some drops.
Pricing and Availability
The set is currently available in the US for an introductory price of around $130. It is expected to cost $170 later.
The white front light uses a replaceable 21700 battery (ARB-L21-5000, 18 watt-hours). The red rear light is different, as it has a built-in 400 mAh battery, presumably with a capacity of about 1.5 watt-hours.
Brightess and Runtime Details
The front light can get very bright. According to the spec sheet, up to 2,500 lumens are possible with a range of 591 feet. However, that is more suitable for flashlight use, since the BC28R gets very warm at that level and only lasts 2 hours and 36 minutes despite throttling. It would also heavily dazzle other road users.
The other modes are more realistic, with 50 to 1,400 lumens and runtimes ranging from 52 hours down to 7 hours.
Rear Light Runtime
Unfortunately, the red light does not offer comparable runtimes. In steady mode, it lasts up to six hours at most. To reach the mid-range runtime of the white light, the flashing mode is required, which increases runtime to up to 15 hours. The full runtimes can be seen in the screenshot below.
On the upside, the front and rear lights can be paired. This means they both turn on at the same time. Fenix does not specify which wireless technology it uses. The rear light can also be adjusted via the front light. However, the distance between them must not exceed 5 feet. A battery level indicator is only available for the front light. Both lights can also be charged while in use if necessary.
Compatibility and Extras
The front light is also compatible with Fenix’s optional ALD-10 Quick Release Bike Mount with GoPro Mount Adapter. The set is currently available in the US for an introductory price of around $130. It is expected to cost $170 later.
