A new Marl LED, available from Aerospace & Defence Products , is an optical and electrical replacement for standard miniature Edison screw filament bulbs in control panels, but lasts 100 times longer and uses less energy.
The new Marl 261 series, which is based on a standard T3¾ bayonet cap, is suitable for industrial control panels and annunciator panels, and offers 100,000 hours of 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 are also offering a cool, white alternative. Both colours are highly efficient, generating little or no heat.
The new 261 series components are fully encapsulated for protection against shock and vibration. They draw just 10mA typically from a 60V AC/DC supply.
