Saxby Vigor LED Bulkhead is a high quality versatile LED. Manufactured from a strong thermoplastic with a shatterproof polycarbonate diffuser. It is suitable for indoor or outdoor use and also commercial and domestic applications. Can also be fitted to both ceilings and walls. The emergency fittings have a separate 3W LED mounted in the centre on the 16W PCB. When the power fails the main LEDs will go off, but the technology inside will light the 3W LED, giving reduced but effective light output from a smaller emergency battery.
