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.

A 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 bipolar, 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.

The new LEDs are also highly energy efficient, drawing just 8mA from a 12V supply - around 25% less than existing versions.

Designated 531, 534, 537, 538, 698 and 699, the new LEDs also feature more modern styling, helping to impart an up-to-date look to instrumentation panels.

The new Marl panel indicator LEDs are available in two sizes, for 8.1 and 12.7mm panel apertures.

The range includes bright nickel plated brass, anodised aluminium and stainless steel versions in red, yellow, green, blue and cold white.

All versions offer a wide 120 degree viewing angle, and are a plug-in replacement for existing Marl and other LED panel indicators.
