For example, with Specialty's new roof- mounted LED strobe light, the LED tower and circuit board are replaceable as a single unit. Also, according to the company, the potted circuit board re- quires no maintenance. Another maintenance-related ad- vantage of LEDs, Riesebosch of CRS says, is that they are generally built to a higher level of ingress protection than incandescent bulbs — meaning that the LEDs are less susceptible to the in- trusion of dust. Life-cycle advantage When feets consider the total cost of ownership for their buses, suppli- ers say that LEDs can help reduce that cost by avoiding the direct and indirect costs of frequent incandescent bulb re- placement. "Generally, school bus maintenance managers have conducted their own life-cycle cost analysis that has led them to conclude LED lighting increas- es up-time and reduces cost over the life of the bus," TRP's Puhrmann says. Riccio of SoundOff says that the typ- ical rated life of an LED varies from about 50,000 to 100,000 hours, depend- ing on the manufacturer and the appli- cation type. Weldon's Barnett puts it this way: "When the lamp fxture is engineered properly, LED lighting should last the life of the vehicle." thomas.mcmahon@bobit.com LED LIGHTING UltraLED's new H3X LED takes the place of an H3 halogen bulb, common to school bus eight-way warning lights.
