Based on a standard T3¾ bayonet cap, the new Marl 261 series is ideal for industrial control panels and annuniciator panels, offering a 100,000 hours service life, compared to 1,000 hours for a typical filament bulb. For many applications the service life of the LED exceeds the service life of the panel, making the component effectively maintenance free.
Marl 261 series LEDs feature full bridge rectification, and operate well from AC supplies as well as DC in either direction. The warm white version, when used with a coloured lens, offers a true optically matched replacement for a filament lamp. Marl is also offering a cool white alternative. Both colours are highly efficient, generating little or no heat.
Like many Marl LEDs, the new 261 series components are fully encapsulated for protection against shock and vibration. They draw just 10mA typically from a 60Vac/dc supply.
