Dubai Municipality (DM) has made the use of Philips-made LED lightbulb the ‘Dubai Lamp’ mandatory for all new developments from later this year. The authority issued the instructions in a memo to all consultancies, contractors and developers operating in the emirate. The light is described as the first ‘commercially viable 200 lumen per Watt LED lamp’. It is also claimed to cut electricity use by 95% and to last an average of 25,000 hours longer than a conventional lamp. The decision comes into effect in December 2017, when the municipality will begin verifying the use of the LED light across all buildings and only grant a building completion certificate if this is confirmed. Manufacturing and distribution of the lamp began in March.
