LF1E LED Illumination Units
LF1E LED Illumination Units
LED illumination units for freezer and
refrigerated display cases.
•LED light sources achieve energy saving, long service life, re-
duced mounting space, elimination of noise, and low heat genera-
tion.
•Available in 4 lengths of 550, 808, 1066, and 1450 mm designed
to meet the width of display cases.
•3 types of light distribution characteristics are available; no-lens,
condensing lens, and dual lens.
•IP54 protection against dust and water.
