Linear LED T8 Lamp
Direct Replacement LED T8
F32T8/8xx/LED/22W/IS Series
5 Year Warranty! Why Linear LED?
Energy Efficient
Reduced
Maintenance
Sustainable
•  Very efficient converting electric power to light output
•  Energy savings compared to T12 systems
•  Lower energy usage reduces energy costs
•  Longer rated life over incandescent, HID, and
fluorescent lighting systems
•  Longer rated life means lower maintenance costs of
lamp change outs
•  Better environmental choice
•  High quality lighting gives design flexibility
•  Can be used with lighting controls without
compromising lamp life
LEDT8 Features
•  Does not require electrical re-wiring to install
•  For use with Electronic Instant Start Ballasts
•  Automatically adjusts to the corresponding Ballast Factor
•  19w (Low Ballast Factor)
•  22w (Standard Ballast Factor)
•  26w (High Ballast Factor)
•  Environmentally friendly – no mercury, no UV or infrared light
•  Low lumen depreciation – maintains brightness over its 50,000 hour
rated life
•  Minimum heat emission, reducing load on building cooling systems
•  No flickers
•  ETL tested to comply with OSHA safety standards
•  DesignLights Consortium® Listed Product (4100K & 5000K lamps).

....Another important consideration when replacing linear
fluorescent lamps with LED products is electrical safety.
Nearly all LED replacements bypass the existing ballast.
HOWARD LEDT8 USES THE
EXISTING INSTANT START
BALLAST
Most have their drive electronics integrated in the tube
HOWARD LEDT8
DOES NOT
while some are provided with external drivers that replace the existing
fluorescent ballast.
HOWARD LEDT8
DOES NOT
Bypassing the existing ballast results in line voltage being delivered to
the sockets (“tombstones”) in the fluorescent fixture, creating a hazard if
a fluorescent lamp is later re-installed in that same fixture.
HOWARD LEDT8
DOES NOT
If a fixture is modified such that it can no longer accept its original lamp,
it must have a label affixed (provided by the LED replacement
manufacturer) clearly indicating this condition.
HOWARD LEDT8 DOES NOT,
NO LABEL IS NEEDED

* The LED26T8 Lamp “self-adjusts” light output that matches the corresponding ballast factor of the supply (or
control) ballast. The new “system matched” light output will meet or exceed that of the one it is replacing.
