Magicshine Seemee 50 V2.0 Rear Light (50 lumens) - Review

1. Introduction

The Magicshine Seemee 50 V2.0 is a compact, USB-C rechargeable 50-lumen rear bicycle light engineered for commuters and urban cyclists seeking reliable visibility and smart syncing capabilities. With smart technologies like PelotonSync Flash and FTR LightSync control, it’s ideal for riders who value visibility, group coordination, and seamless front-and-rear lighting control—even on a budget.

2. Design & Build Quality

Featuring a sleek PC+ABS body and high-transparency Optillumin lens, the Seemee 50 V2.0 ensures maximum light diffusion and visibility. The light weighs just under 30 g—light enough not to interfere with handling—but still feels solid and durable. A silicone strap enables quick and secure mounting to most seat posts. With an IPX6 waterproof rating, this tail light stands up to heavy rain, while a lock function prevents accidental activation during transit.

3. Performance & Features

Bright enough for city commuting, the 50 lm output shines through the Optillumin lens clearly. Battery life varies by mode: up to 30.5 hours in Eco-Flash, around 10.5 hours in Day Flash, and about 3-4 hours in High mode. The USB-C recharge takes about 2 hours for a full charge. Smart features include:

• PelotonSync Flash, for synchronized flashing with other Seemee lights
• FTR LightSync control, enabling simultaneous front and rear light operation with compatible Magicshine systems and the MJ-6558 remote.
  Also includes mode memory and battery-level indicator for user convenience.
