Marl Optosource has introduced a range of LEDs that achieves the best ever lumens light output per penny cost of the LED - between 25% and 50% more light output than comparable LEDs of the same cost. The LEDs feature clear lenses and are available in a wide range of colours including red, yellow, green, blue and white. They are offered as discrete components, or can be assembled into complete LED panel lamps at Marl’s Ulverston manufacturing site. This customisation includes protecting the LED assembly against shock and vibration, providing a polarity-insensitive solution that can even operate in an ac environment, protecting the LED against moisture, dust and heat, and matching the colour of an existing incandescent panel lamp.
