These look almost exactly the same as normal MR16 halogens and, not only do they reduce the amount of electricity required, they also
last five times as long (5000 hours) meaning the cost of ownership is
reduced also.
Although the energy savings are less than switching to LED lamps, these have the advantage of being able to be dimmed on standard dimming switches and circuits and can be disposed of with normal household waste.
These lamps are not subject to the WEEE (Waste Electrical and Electronic Equipment Regulations) recycling charge as set by the lamp manufacturers.
