Bicycle Headlight Beamshots

On this page you can find the Beamshots of Purple Dog Custom Bicycle Headlights.

Unless otherwise specified all of my headlights use optics designed to meet German StVZO standards which offer superior illumination as compared to ‘simple round beam’ optics.

PLEASE NOTE: As pretty much all my (dynamo) lights are built with regulated power supplies, there is no change in intensity as you speed up. The lights might dim at low speed or flicker (due to insufficient power output of the dynamo), however, what you see here is what you get. Speed is not a variable.

Camera Settings

Canon 550D
28-135mm Lens with Image Stabilisation set at 28mm
f5.6 aperture
2 second manual exposure
ISO 400

I have done my best to keep camera/lights positioning the same. As more lights get added to the Purple Dog range of products, the beamshapes will be added to this page.
