4.5W Citizen CL-L251 LED series offer four times more efficiency than halogen

(26/08/2010)

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

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.
