Six fixtures cover a floor of hallways, stairwells and exit doors in one purchase, which is how emergency lighting is actually specified rather than unit by unit. Each switches to its own 700mAh Ni-Cd battery the moment mains power fails and holds at least 90 minutes of steady light, enough for an orderly evacuation. Twenty four SMD2835 LEDs give 230 lumens of even, flicker free output that marks escape routes clearly without glaring in smoke. Both heads pivot horizontally and vertically so a single fixture can light a corner and a stair flight, cutting the number of units a building needs. The AC 120 to 277 volt input range covers most commercial supplies, the housing is flame retardant PC with an ABS lens, and a test button makes routine compliance checks straightforward.
