Editor's Note: This article is part of Mtbr's 2016 Bike Lights Shootout. See the 2016 Headlights Index and Commuter and Tail Lights Index.
These backyard beam patterns allow you to gauge the throw and width of a light in a controlled environment. The bike in the middle is set at about 25 yards and can show far the light can throw. The width, consistency and color of the beam are key information that can be learned from these photos as well.
For lights over 3000 Lumens, we'll photograph the beam in a much bigger landscape to really showcase their brightness.
The camera settings we used are the following:
- Camera: Olympus OM-D
- Setting: Full manual
- ISO: 200
- Exposure: 1.6 seconds
- Aperture: f/4.0
- Focus: Manual
- White Balance: Daylight
- Quality: JPEG High
