Community Tips
Always use a voltage tester on the fixture and wires before touching any connections, even after turning off the breaker—a faulty breaker or double-switched circuit can leave live current running to the fixture. Klein Tools VDV500 ($20-30) detects both AC voltage and continuity, preventing the most common electrical injuries on this task.
Apply silicone caulk around the fixture mounting plate before screwing it to the wall to prevent water infiltration that causes corrosion and premature failure. DAP Silicone Caulk ($4-7) creates a weatherproof seal that outlasts paintable caulks by 5+ years on exterior fixtures exposed to freeze-thaw cycles.
Exterior fixtures rated IP65 or higher withstand moisture far better than standard indoor models and reduce troubleshooting calls by 80%. Spending $15-25 more per fixture on weather-sealed construction (versus basic IP44 ratings) typically adds 10+ years to fixture lifespan in coastal or humid climates. ---
