LF1A LED Illumination Units
LF1A LED Illumination Units
Energy saving LED illumination units,
only 1/3 power consumption compared
with uorescent lamps.
•40,000 hour service life, no maintenance needed.
•LED modules and highly efficient heat dissipation technol-
ogy achieves low heat generation.
•Only 22mm high, making it possible to installing inside a
small space.
•White, warm white, yellow, and red.

Features
Suppressing glare, the bright,
clear white illumination color lights
up a target object clearly.
Warm color similar to that of an
incandescent light bulb. This
illumination color gives off a color
temperature of 2800K.
Yellow illumination color gives
off an emission spectrum with a
dominant wavelength of 590 nm.
It does not include 500 nm or
shorter wavelengths.
Red illumination color gives off
an emission spectrum with a long
wavelength (dominant wavelength
of 625 nm).
