LAZER ST4 Evolution - black

On an unlit road what matters is not the number on the box but how far ahead you can see the edge of the tarmac. This lamp lights it to 555 m on the 0.25 lx line.

The manufacturer quotes 4,136 lm of output, 204mm wide, 0.67 kg. ECE R112 - Ref: 10 approval means the lamp is homologated as a driving light, not restricted to off-road use.
