LEDtronics has released an LED bulb to replace conventional T6 incandescent tubes in exit signs. According to LEDtronics, the XL-TPW Series Pure White LED Exit Light Bulbs are more reliable, last longer, and use less energy than the conventional T6 bulbs that they replace.

LEDtronics points out that their solid-state design with no filament renders them impervious to shock, vibration, frequent switching and environmental extremes. They boast an average lifespan of more than 50,000 hours (5.7-plus years), or more than 20 times longer than the equivalent incandescent bulb.
