Alpha 3

Product Description:

A round surface mount standalone 3-hour emergency LED, featuring a halo effect charge/fault indicator. The light source is available with either open-area (anti panic) which emits 268 lumen, or a corridor (escape route) optic that emits 266 lumen. The Alpha Surface range operates with the latest LiFePO4 batteries that not only last far longer than traditional emergency lighting batteries but consume far less power.
The Alpha 3 comes with Besa and standard fixing points and is available in either white (RAL9016) or black (RAL9005). It can be supplied as either basic non-maintained emergency or DALI-2 Self-test operation.
