LED tube lights that are ideally designed for passenger buses and railcars

Fluorescent-Replacement LED T8, T12–adapted, 4Ft–Long Tube Lights Well Suited for Passenger Buses, Railcars

LEDtronics, Inc. has announced energy–efficient, vibration–resistant T8 and T12/2–pin fluorescent–replacement LED tube lights that are designed for passenger buses and railcars. The series LED48T8–288 Bi–Pin LED Tube Light fits into standard G13 bases and is designed to directly replace conventional T8 and T12 fluorescent tubes that provide interior lighting for light rail, motor coaches, buses, railway passenger cars, railway carriages, trolley cars and subway cars.

The 48–inch–long LED48T8–288 tubes operate on a wide voltage range of 24 to 42 volts DC. They provide the equivalent light output of 24 to 32–watt fluorescents while typically consuming 21 watts at 30 VDC, and a maximum of 34 watts at 42 VDC. While conventional fluorescent lamps typically have an ideal–condition rated lab life in the range 8,000 to 24,000 hours, the LEDtronics tube lights have a real world operating life of 50,000 hours and more—5.7 years of continuous light output.

The construction of a UV–resistant polycarbonate housing over the LED tube provides increased protection — no glass to break and no mercury environmental hazards to worry about as with fluorescent tubes. In addition, the housing shields against many environmental effects, allowing them to be placed in locations where typical tube lights would be more vulnerable to the elements. In addition, LEDtronics tubes perform well in a wide range of ambient operating temperatures: ~ –30°C to ~ 50°C, making them well suited for applications subject to frequent on–off cycling such as those in recreation vehicles, bus and motor coaches, light–rail passenger cars, subway cars and trolley car interior lighting, while the aluminum back cover helps with better heat dissipation and a longer lifetime for the LEDs.

The LEDtronics LED48T8–288 tube lights deliver 1,095 lumens at color temperatures of 4,800 K to 5,200 K (pure daylight white) compared to the average 813 lumens for equivalent conventional fluorescent tubes. The LED48T8–288 tube lights provide a brightness of up to 341 maximum candelas across a 123° beam pattern, with an impressive CRI of 80. Other viewing angles, tube lengths and a variety of LED light colors are available for OEM customers.

Other benefits of LEDs over fluorescents include: Quick and easy installation to minimize retrofit costs; no ballast nor starter needed, thus no radio frequency to interfere with radio and cell phone signals; instant, full–strength light–up; no buzzing or flickering; and directional distribution of light—good for interior task lighting.
