For solar powered systems, increasing the intensity from the original factory setting may lead to reduced battery life or may impact system performance and reliability. Please contact Carmanah for assistance if you would like to increase the output intensity of the fixtures.

For RRFB applications:

RRFB light bars must meet a minimum light intensity standard to be FHWA, MUTCD, IA-21 compliant. If you are considering reducing the daytime, factory setting, for RRFB light bar output intensity, please click the blue chat box in the bottom right corner of the page 🗨️ at
