What it actually does
The Moon Orion Sense is a bicycle rear light rated at up to 50 lumens under the FL-1 standard. The manufacturer quotes up to 50 hours of runtime and a 2.5-hour charge via USB-C. Built-in sensors detect braking, parking and ambient light; there are 2 steady and 4 flashing modes, a day mode, an automatic safety mode and mode memory. The light is IPX5 rated, which the maker describes as suitable for light rain, and weighs about 22 g. How it mounts to the bike, and whether the 50 hours apply to the lowest mode, is not stated.
Reasons for
- Brake, park and ambient light sensors
- Up to 50 hours runtime (manufacturer claim)
- Only about 22 g
- Charges via USB-C
Reasons against
- IPX5 covers light rain only
- Shipping CHF 17.99 is steep
- Mount not described
Who should skip it
Commuters who ride in heavy rain should note that IPX5 is, per the manufacturer, only meant for light rain. Occasional daytime riders will get by with a simpler light without sensors for less. Shipping of CHF 17.99 weighs heavily on a single small purchase.
