Shield your eyes! Man creates 90,000 lumen LED front light + video

We’ve tested some bright cycle lights here at road.cc, but nothing even comes close to the staggering claimed 90,000 lumen LED front light created by Daniel Riley of Stratus Productions in the US.

It hasn’t been designed as a cycle light. No cyclist really needs that much light (or do they?). But we thought it interesting enough to share with you all. Light technology has advanced significantly in the last 10 years with LEDs getting bright every year and run times getting longer.

There’s a healthy market for homemade LED lights, but we’ve never seen anything this ambitious before. The homemade light uses a row of ten 100W LEDs, each outputting  9,000 lumens. Altogether, that’s a mighty 90,000 lumens. Each LED has its own lens which generates a 60-degree beam pattern.

Don’t expect much in the way of battery life, though. With two batteries running in tandem, the battery life is a piffling 10 minutes. Better make sure the ride home from the office is a short one! That sort of lighting capacity generates a lot of heat, so each LED is directly mounted to a heatsink.

The LED lights are mounted to an aluminium frame to hold them all together. It’s so wide that you might struggle to fit it to the front of your bike. It neither is it very light, due to the complexity of the design, weighs 10lb (4.54kg).

While we’re clearly not going to see this light on a bicycle any time soon, it does show what is possible with a bit of creative thinking and a load of the latest LED lights. And no gaffa tape was used in the creation of this light
