According to Marl, replacing standard dichroic halogen lights with its LED products will pay for themselves within a year when operated for 18-24 hours a day, and will last for nearly six years (50,000 hours) continuous illumination.
The Marl 256 series MR16 LED downlight matches the output of a 35W halogen light but draws just 6W. It interfaces with all standard MR16 sockets allowing direct replacements, and in most instances, can be powered from the same 12V AC or DC supply. The modules emit zero ultraviolet or infrared radiation in the light beam, and are available in warm white or cool white form.
The Marl 257 series MR11 downlight is offered in two power levels, which produce the light output of a 20W and a 10W halogen respectively but draw less than 2W. The 10W reading lamp is exactly the same size as the MR11, whilst the all-purpose 20W lamp is 10mm deeper.
