Welcome to FOUR4TH -
1200 Lumens Bicycle / Mountain Bike LED Lights

We are engineers by day, and bike riders by night.
So when we couldn’t find the light we wanted,
we decided to make it. Here it is – the light of our life.

• Precision CNC machined from solid aluminium and acetal

• Weighs 63g and gives 1200 lumens of light from 4 LEDs

• Designed for mountain biking and road riding

• Lithium polymer (LiPo) batteries give 3.5 hours run time (approx)
on 2600 mAh rising to 6.5hrs on 4500 mAh

• Aircraft standard components with IP67 waterproof rating

• 4 LED lens options - spot, medium, wide, commuter

• Large on/off switch is easy to use even with winter gloves

• Unique attaching system – removes easily from bars and helmet
