Larson Electronics has developed a new 23 watt dimmable LED tube lamp that is an excellent choice for upgrading existing T8 dimming fluorescent lamp fixtures as well as a direct replacement for our LED light fixtures.

23 Watt Dimmable LED Tube ideal for fluorescent upgrade

Larson Electronics releases a Four Foot 23 Watt Dimmable LED Light Bulb

The LEDT8-48-D 23 watt T-series LED bulb from Larson Electronics works with any T8 fluorescent light fixtures, can be configured for any T series fluorescent bulb fixture and requires no ballast for operation.

Power for this dimmable LED tube is single ended, meaning line and neutral voltage are applied to the same end. Internally, the operator simply brings the black wire to one pin and the white wire to the other. When installing this tube in a fluorescent light fixture, the operator must bypass the ballast and wire the power directly to one end of the LED tube. This feature makes the tubes an ideal upgrade for four foot fixtures with failed ballasts. This LED lamp features rotating pins, allowing operators to adjust the direction of light dispersion after installation. While fluorescent lamps are Omni-directional and illuminate 360°, the LED style replacement lamps are directional and offer a 160° beam spread.

The polycarbonate lens diffuses the light and makes this bulb ideal for food safe environments as there is no glass. The aluminum housing serves as a heat sink and provides rigidity and strength for this LED bulb. These are the first generation of our dimmable LED tubes and they produce 105 lumens of light per watt for a total of 2,415 lumens per bulb. This dimming LED tube uses electronic silicon control dimming and has been tested on all Lutron and Leviton electronic dimmers. When using electronic dimmer switches, the LEDT8-48-D LED bulb will dim from 0% up to 100%. These multi-voltage LED bulbs run directly off any voltage ranging from 90 volts to 132 volts, including 110 volts, 115 volts, and 120 volts AC. This lamp will not work on any voltage outside of the 90-132V AC range and internal damage may occur when higher voltage is applied to the lamp.

“These new LED tubes were designed for our explosion proof light fixtures but may be used as replacements in standard fluorescent light fixtures,” said Rob Bresnahan with “By simply passing the ballast in a fluorescent fixture, installation is very simple.”
