T3¼ (9mm) Single-Contact Screw-In LED Bulbs

TORRANCE, Ca. - LEDtronics® announces T3¼ (9mm) Single-Contact Screw-In LED Bulbs that beautifully lights up many different types of applications. These LED bulbs fit most battery powered book lights and flashlights that offer a 9mm screw-in incandescent bulb and Improve Battery Life 16 times longer over incandescent bulbs.

These high quality LED bulbs produce very little heat, thus reducing the risk of fire hazards. Furthermore, these great 9mm LED bulbs only consume tenth of power compared to the usual incandescent bulb used in these applications!

9mm LED bulbs come in cool white (8000) Kelvin and puts out 13,000 MCD at 20° angles. These 9mm LED bulbs are offered with either one cool white LED or three cool white LEDs. Total Light Output for one LED: 15cd. The 3 LED bulb, Total Light Output: 45cd. Voltage range is 4.8 Volt / 5 Volt / 6 Volt DC.

Solid-state design renders LEDs impervious to shock, vibration, frequent switching, and environmental extremes. With an average life span of 100,000-plus hours (11 years), 50,000 hours for White LEDs. LED lamps operate more than 20 to 30 times longer than the equivalent incandescent lamp! Savings from reduced maintenance costs and downtime quickly return the capital investment expenditure! LED lamps produce almost no heat and require 80% - 90% less operating power than equivalent incandescents, making them as friendly to the environment as they are to the operating budget.

Founded in 1983, LEDtronics® leads where others only follow when it comes to designing, manufacturing and packaging state-of-the-art LEDs to meet the world’s constantly changing lighting needs.
