MARL 24V LED T-1 3/4 Midget Groove Bulb, White

The MARL 24V LED T-1 3/4 Midget Groove Bulb is an advanced filament replacement lamp designed to offer superior reliability and performance in demanding industrial and signalling applications. Its core technology features a flat-topped, single-chip LED which provides enhanced, even illumination, making it perfect for backlighting large lens areas and switches.

A key advantage of this LED bulb is its significant lifespan, averaging an impressive 100,000 hours. This dramatically reduces maintenance frequency and replacement costs compared to traditional incandescent bulbs. The design incorporates protection against electro-static discharge (ESD), a common issue in environments where products are frequently handled, ensuring stable operation.

The bulb operates on a 24V supply with a current rating of 20mA, delivering a luminous intensity of 3cd. It features a standard centre contact anode and a water-clear lens for maximum light output. Its performance is engineered to be consistent, with the understanding that LED forward voltage and current are dependent on the ambient operating temperature.

This unit is a direct, drop-in replacement for T1-3/4 midget groove S5.7s base fittings, facilitating easy upgrades without modification. For added installation flexibility, reverse polarity options are available to suit various circuit configurations.
