Railroad authorities are some of the most demanding customers for lighting designers because safety is paramount. When the signal is 3 km from the train driver, optics need to be precise and colors accurate. Light Engines engineers are pioneers in LED rail signals with the tools, lab, and knowledge to help on your rail project.
Built around our individual light points, we can design a custom module for your high volume OEM application.

Notes:
1. The luminous intensity is measured on the optical axis.
2. Per 1931 CIE Chromaticity Diagram.
3. 2 is the off-axis angle with the luminous intensity of one half the on-axis intensity.
