There has been a great
leap forward in LED technology over the past five years, and the
brightness achievable from the best LED light sources has increased
dramatically.
Increases in overall light output and improvements
in efficiency mean that LED lighting is now more than a match for
halogen in terms of light output, and almost twice as efficient.
LEDs
offering 100 lumens per watt or more are available, giving 70 lumens
per watt when installed in a good quality fixture. This matches the
performance of fluorescent tubes, allowing for the inverter losses. The
latest products from Citizen, for example, deliver 102 lumens per watt
in the 350mA version, and the 1,500mA version in the same range can
deliver 1,200 lumens output.
