The Larson Electronics
LEDT8-28W-V1 28 watt T-series LED tube lamp is an excellent choice for upgrading
existing T8 fluorescent lamp fixtures to LEDs as well as a direct replacement
for our own LED light fixtures. This LED lamp is LEL listed, providing 125
lumens per watt for a total of 3,500 lumens per lamp. These T8 LED replacement
lamps offer 50,000 hour lamp life, over twice that of T8 or T5HO fluorescent
lamps, while offering impact and vibration resistance far exceeding traditional
28 Watt T-series LED Bulb works with any T8 fluorescent light fixtures, can be
configured for any T series fluorescent lamp fixture with G13 bi-pin tombstones
or sockets, and requires no ballast for operation. To increase safety during
installation and routine maintenance, these lamps are wired for single sided
power with internal integrated LED driver housed within the tube. Internally,
you simply bring the black wire to one pin and the white wire to the other. 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.
fluorescent light fixtures with electronic ballasts, the operator needs to
bypass the ballast and wire the power directly to one end of the LED tube (black
wire to one pin and white wire to the other). Thus, this is an ideal upgrade for
4 foot fixtures with failed ballasts. These LED fluorescent style bulbs are
universal voltage and run directly off any voltage ranging from 100 volts to 277
volts AC 50/60 Hz. The internal LED driver is a "smart" driver, sensing the
incoming voltage and adjusting accordingly to provide the current required by
the lamp. This allows operators to simply wire the fixture to voltage within the
120-277V range, no modifications required. This includes commonly found voltages
such as 120V 60Hz, 220V 50Hz, 240V 60Hz, and 277V 60Hz. We also offer a 12/24V
AC/DC version for low voltage applications for AC or DC power. Low voltage
fixtures require no modifications between 12V and 24V power sources, nor between
alternating and direct current supply.
Unlike gas burning and arc type
lamps that have glass bulbs, LEDs have no filaments or fragile housings to break
during operation. Instead of heating a small filament or using a combination of
gases to produce light, light emitting diodes (LEDs) use semi-conductive
materials that illuminate when electric current applied and emitting light. With
LED lights, there is no warm up time or cool down time before re-striking and
provide instant illumination when powered on, adding to the reliability of LED
technology. By nature, LED light sources run significantly cooler than
traditional lamps, reducing the chance of accidental burns and increased
temperatures due to heat emissions. This solid state design of light emitting
diodes provides a more reliable, stable, durable, and energy efficient light
source over traditional lighting.
LEDT8-28W-V1 features specially designed rotating end caps. Fluorescent lamps
provide a full 360° beam coverage around the lamp. Since most fluorescent
fixtures require directional lighting, reflectors have to be used to bounce the
light back towards the intended target area for illumination. LED lamps are
directional, which eliminates the need for back mounted reflectors and reduces
wasted and lost light. However, the tombstones for existing fixtures may
position the face of the LED lamp in a direction facing away from the target
illumination area. With the rotating pins, operators can reposition the lamp so
the face of the LED tube is positioned properly within existing fixtures. This
also allows for fine tune adjustment of each individual lamp within fixtures
containing multiple lamps.

Fluorescent T8 bulbs (right) in a body shop
are the second generation of our 28 watt LED tubes. Efficiency for this LED lamp
is 125 lumens per watt, for a total of 3,500 lumens per bulb. We offer a choice
of 3000K warm white, 4500K natural white, and 5600K cool white color
temperatures and clear, frosted, or heavy frosted lenses. The LEDT8 series of
LED lamps are designed for direct replacement of 4ft fluorescent fixtures with
G13 bases for replacing four foot T8, T8 high output, T12, T12 high output, and
T12 very high output florescent lamps. Additionally, these lamps can be used in
fixtures that currently use a G5 to G13 adapter socket using T5 lamps. Please
note, this tube is 47" in length and will not fit properly in fixtures designed
to accept 45" T5 lamps without adapters.
LED fluorescent tube replacements can be used as upgrades or replacements to our
own explosion proof fluorescent lights, explosion proof paint spray booth lights
as well as any other T series light fixture the operator already has in house.
We have specially designed these for our explosion proof light fixtures,
however, they can be used as replacements in standard fluorescent light
fixtures. In our facilities, we replaced worn or spent fluorescent bulbs with
these LED bulbs by removing the ballasts and bringing the white wire to one end
and the black wire to the other end of the LED tube.
