Marl has launched a Citizen LED equivalent to the popular MR16 halogen light, offering over four times better efficiency.

Marl LED is four times more efficient than halogen Available in the UK from Marl, the 4.5W Citizen CL-L251 delivers 290 lumens of light output at a colour temperature of 3000K with good colour rendering “Ra85”, equivalent to a standard 20W MR16 halogen. The range is available with colour temperatures up to 5000K, delivering up to 425 lumens from 4.5W. The CL-L251 has a luminous efficiency of up to 106 lumens per watt, compared to 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.

In addition to the direct cost savings, the Citizen CL-L251 from Marl provides significant indirect energy and maintenance cost reductions. The LED light emits much less waste heat than Halogen, reducing the load on air conditioning. The LED has a ten times longer lifetime of 40,000 hours or 4.5 years continuous use, compared to typically 4000 hours for an MR16 halogen light.
