Exposure BoostR 3 ReAKT Rear Light

Season:2027

Brand:Exposure

Code:EXPBOOSTR3RA

This is the rear light for riders who want to charge as rarely as possible.

Output is 200 lumens in flash and 75 constant, both up on the previous generation, and the battery is larger, giving up to 70 hours depending on mode. Charging is USB-C Power Delivery, which Exposure put at up to 66% faster than before and which works from a power bank as well as a wall socket.

The optics are worth understanding, because they do two different jobs. An 8 degree collimated spot lens throws the light a long way down the road behind you, which is what gets you noticed by a car still some distance back. A 270 degree Commute Lens spreads output to the sides, which is what gets you noticed by the driver waiting at a side road. The DayBright pulse is the pattern designed for daylight, and Exposure claim it is visible over a kilometre away in bright conditions.

ReAKT runs automatically. The light flares under deceleration in both constant and flash modes, and adjusts to ambient light, dimming in a tunnel and lifting in open daylight. Peloton reduces output when it detects a rider's front light close behind, then restores the previous setting once they move on.

The body is CNC-machined 6063 aluminium, rated IP67 and IK09. Intelligent Thermal Management pulls LED power back if the light gets hot and restores it once it cools, so output is managed rather than simply cut. A single press with the light off shows the battery level for five seconds.

Seven bracket options are available, covering seatpost, saddle rail, aero post, stud, helmet, GoPro and QR fittings.
