The Lykos 4ft integrated LED batten light with 3-hour emergency function has been designed as a direct replacement for single T5 & T8 linear outdoor fluorescent luminaires. Consuming only 20w to provide 2000 lumens, this single LED non-corrosive fitting is an ultra-energy-efficient choice for industrial environments such as garages, public car parks, workshops & food preparation areas which require tough, weatherproof fittings. This Lykos single LED batten light comes with a 20W integrated LED strip with a 50, 000 hour rate life, meaning it will be years before the fitting will need to be replaced while also removing the need for maintenance, subsequently lowering costs. The tri-proof fitting is constructed from an IK08 impact rated moisture & acid-resistant ABS body with polycarbonate diffuser. With an IP65 rating, it is suitable for indoor & outdoor use making it ideal use in areas where a tough robust led batten light is required. The stainless steel anti-tamper clips mean that this fitting is also vandal proof. Installation is simple thanks to the two loop-through continuous feed terminal blocks (with continuous live feed). This saves an incredible amount of time, especially with projects requiring multiple fittings to be installed, as the loop-in/loop-out terminals make it possible to wire directly from fitting-to-fitting.A built-in emergency battery has a discharge time of at least 3 hours, making it ideal in scenarios such as power cuts or other low light scenarios. The supplied battery takes 16 hours to fully charge & the green light indicator to show when the battery is charged. An integrated "self-test" button provides the ability to test the emergency mode. The Phoebe Lykos LED batten light fitting is suitable for conduit, surface, or suspension mounting.
