A bulb that exceeds a fixture’s wattage limit can overheat the fixture, wiring, or nearby materials.
A fixture’s maximum wattage is a safety limit, not a target for brightness.
Lamps and ceiling fixtures can have different bulb limits. Check each fixture’s label rather than assuming one bulb suits them all.
Read the fixture label before fitting a replacement bulb. Stay within its maximum wattage and follow its bulb-type instructions.
If a fixture’s rating is missing or unreadable, ask the manufacturer or an electrician which bulb is suitable.
Do not install a higher-wattage bulb to brighten a room. Choose lighting that provides the light you need within the fixture’s rating.
