DDP Develops Rugged High Intensity LED Lamp to Replace Incandescent Bulbs on Rail Cars
October 26, 2011
At upwards of 90 lumens, the DDP 895L Series LED lamp provides a drop-in replacement of the 895 incandescent bulb by meeting industry standard sunlight visibility and viewing angle requirements. Available in red, amber, turquoise, blue, warm white, and lunar white, the DDP 895L will illuminate all industry-standard indicator lenses without mechanical or electrical modification.
Designed to operate at 37.5 volts DC, the 895L LED lamp includes an internal voltage regulator to allow even illumination despite common voltage fluctuations between 20 - 45 volts DC. Additional internal circuitry protects the DDP 895L from transient voltage spikes and circuit noise.
"We designed our 895L Series lamps in response to numerous requests from rail maintenance engineers across the country. The incandescent bulbs require constant costly replacement. The challenge was to develop an LED lamp that was a drop-in retrofit, and still be able to provide the sunlight visibility, constant brightness despite voltage fluctuations, and extreme mechanical shock in the rail environment." said Tony Toniolo, DDP President.
The DDP 895L Series incorporates first tier LED technology providing upwards of 100,000 hours of operating life. Drawing only 45mA, the DDP 895L operates at one-tenth the current of the 895 incandescent bulb - greatly increasing battery life and reducing inductor maintenance on rail vehicles.
