The Techmalux KE/418 IP67 lamp is a high‑frequency compact fluorescent tube rated at 24 VAC/18 W with an IP67 enclosure designed for harsh industrial environments. Common failure points for this class of lamps include ballast degradation (leading to flicker or no light), phosphor wear (resulting in dimming), and seal leakage causing moisture ingress that shorts the internal circuitry. Begin troubleshooting by verifying input voltage and continuity across the ballast; inspect the tube for discoloration or cracking, and check for any visible corrosion or water damage inside the IP67 housing. If the lamp still fails after these checks, test the ballast output with a multimeter to confirm proper high‑frequency operation before proceeding to component replacement.[oss-gpt-20b]
