First disconnect power, then loosen the knurled bolt, remove the housing, handle the lamp by the base, align it with the retention brackets, push it in, secure with the retaining clip, and re‑install the housing.
Do not mount the fixture on or near combustible surfaces, never operate without a lens, always lock the color frame retaining clip, and use only HPL lamps to maintain UL/cUL compliance.
Only HPL (High‑Pressure Mercury) lamps are approved; using other lamp types voids UL/cUL safety compliance and the warranty.
