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 10 imes longer lifetime of 40,000 hours or 4.5 years continuous use, compared to typically 4000 hours for an MR16 halogen light, adds the company.
