Back to Regulations Overview

LED Technology - Annex B.

In Annex B of BS 5266-1:2025, the standard addresses the fact that LED technology and intelligent lighting controls are now replacing the older technology and becoming the first choice for emergency lighting. The new technology opened up the doors to new components, systems and controls that were previously not known.
