What You'll Learn
What it means: A light fixture has a bulb with a higher wattage than the fixture is designed for.
Code violation? Yes.
Danger level: High. The bulb's intense heat can scorch or melt the socket and insulation on the fixture's wires, which increases the risk of arcing — sparks that jump through the air from one wire to another — a chief cause of electrical fires. The damage to socket and wires remains even after the bulb has been removed.
Solution: Stay within the wattage limit listed on all light fixtures made since 1985. For older, unmarked fixtures, use only 60-watt bulbs or smaller.
