Marl's LED beats fluorescent on efficiency

New low-watt Citizen LED light engines from Marl enable the creation of replacements for fluorescent strip lights – offering well over 25% better efficiency and at least four times longer lifetimes. An array of five of the chips matches the light output of a 1.2W fluorescent tube.
According to Marl, the announcement means LED lighting is now the low energy lighting of choice – a position held by fluorescent technologies for some time. “With the announcement of the latest generation of Citizen devices LED lighting is more efficient and longer lasting than any other lighting technology, and can match the light output of all but the most specialist lights,” commented Marl Managing Director Adrian Rawlinson. “It is also more robust than fluorescent, and eliminates the risk of broken glass tubes coated with poisonous phosphorous based chemicals.”
The highly flexible chip-style packaging for these Citizen devices lends itself to the creation of a host of innovative lighting effects. They can be mounted to form circles, squares or other shapes as well as in linear arrays. Like all LED lighting, the new Citizen CL-824 series delivers directional illumination in a downward cone over a 120° arc. This eliminates wasted light.
Available in the UK from Marl, Citizen CL-824 series LEDs are ultra-compact high efficiency devices in a robust chip-type packaging. A linear array with certain chips can deliver a final efficiency of 74 lumens per Watt – compared with around 56 lumens per Watt from a typical fluorescent fitting. Rated life for the LED chips is 40,000 hours, compared to 10,000 hours for a standard fluorescent tube.
