Marl International Limited specialise in the design, manufacture and supply of visible LED indication, illumination, components and systems.

LEDs offer you numerous benefits over conventional filament indicators. The first is that they have an average life of 100,000 hours, which equates to 10 years continuous use, saving you money on maintenance costs.

They are resistant to shock, vibration and mechanical damage; making them ideal indicators for arduous environments and running at significantly lower currents - typically 20mA - drastically reducing running costs.

Overall, LEDs provide reliable fit-and-forget indication at greatly reduced costs in comparison to filament lamps.

New Marl panel indicators offer multiple benefits»

Panel Indicators Marl’s stylish new range of metal bodied panel indicator LEDs is not only up to 25% more energy efficient than the earlier versions, but is also truly bi-polar, and can be driven from a wide voltage band.

The new Marl panel indicator LEDs will operate from any voltage in the range 12-28V with minimal variation in brightness making them ideal for battery powered systems and other applications where input voltage is subject to wide variations. Unlike most LEDs they are insensitive to the polarity of the incoming power supply, and will work equally well wired either way around.
