LUXEON
FEATURES
Superior lumen maintenance —
by design
Luxeon power light sources contain no
epoxy. Epoxy is prone to optical decay
over time, resulting in poor lumen mainte-
nance. Luxeon technology delivers
superior lumen maintenance compared to
other solid state sources and conven-
tional lighting.
