Trek Ion 200 RT/Flare RT Light Set vs Ravemen K1800 Bike Light

These are not really rivals: the Trek set is a front and rear daytime visibility package, while the Ravemen K1800 is a single high-power headlight. Buy the Trek set if you want to be seen in daylight and need both ends covered with a light, compact pair. Buy the Ravemen if you ride unlit roads or trails at night and need a bright, long-throw beam. The Trek pair is lighter and simpler; the Ravemen is heavier, aluminum-bodied and far more powerful, with a power bank feature.

• Choose the Trek Ion 200 RT/Flare RT set if you ride in traffic and daylight and want front and rear visibility in one small, light, USB-rechargeable package.
• Choose the Ravemen K1800 if you need a single very bright headlight for dark roads, trails or fast descents, and want a metal body and USB-C power bank output.
