All LED offers this fantastic 15W circular LED bulkhead for both indoor and outdoor lighting purposes. It has a built in emergency 3 hour battery ensuring that it stays lit during fault conditions. The IP65 casing will ensure that it can withstand almost all weather conditions and the robust internal electronics are rated to work with temperatures as low as -20 and high as 55C. The customisable colour output of the light is a very appealing feature for not only the choice but also making it simpler to match the unit up to already installed lights. You can choose between 3000K warm white 4000K cool white or 6500K daylight (brightness may vary depending on the colour).
