Marl Boasts MR16 LED Bulb Four Times More Efficient Than Halogen
July 21, 2010... Marl of Ulverston, UK, has launched a Citizen LED equivalent to the popular MR16 halogen light. The company contends that the LED-based MR16 bulb offers over four times better efficiency.
The 4.5W Citizen CL-L251 delivers 290 lumens of light output at a color temperature of 3000K with good colour rendering "Ra85", equivalent to a standard 20W MR16 halogen.
The series is available with color temperatures up to 5000K, delivering up to 425 lumens from 4.5W. It has a luminous efficacy of up to 106 lumens per watt, compared to an abysmal 16 lumens per watt for a halogen light. Since the drive voltage of the CL-L251 is 9-10V, the LED can be packaged as a drop-in replacement for the standard halogen light.
Marl says that the the Citizen CL-L251 provides significant energy and maintenance cost reductions. The LED light also has an estimate lifetime that is ten times of 40,000 hours that is ten times longer compared to typically 4000 hours for an MR16 halogen light.
