Phoebe LED Melana 18W LED Bulkhead with Microwave Sensor This surface mounted LED bulkhead from Phoebe LED features a tri-colour switch that means that you can change the colour temperature of the light at the point of installation. The three colour options are 3000K warm white, 4000K cool white, & 5000K extra cool white. The Melana is also built with an integrated microwave sensor that allows the bulkhead to illuminate automatically when a presence is detected. The sensor has a 140° angle & 5-7 metre detection range. The light operates at its full output as long as it detects a presence, & will dim to 10% after 30 seconds of no detection. It is well-suited to hotel & hospital corridors where footfall is intermittent. The bulkhead emits a bright 1700 lumens at its full output, in any of its colour modes, & its opal diffuser softens the light & reduces glare. It is IP54 rated, so it can be used in bathrooms, while its robust polycarbonate construction & long 40, 000 hour life make the Melana a reliable, cost efficient alternative to traditional fluorescent lighting.
