Yes, unless the box says otherwise. Some LEDs are marked “not for use in totally enclosed fixtures”: a closed glass holds in heat, and heat shortens an LED’s life. In a dome, globe or jar fixture, use a bulb without that warning, or one listed as rated for enclosed fixtures.
Why heat matters to an LED
The hotter an LED runs, the faster its light fades and the shorter its life. LEDs use a heat sink to carry heat away and keep from overheating, so a closed glass that holds the heat in works against them.
What to look for on the box
“Not for use in totally enclosed fixtures” (or “luminaires”): open fixtures only.
“Not for use in recessed fixtures”: not for recessed cans either.
Enclosed fixture rated: Feit lists it in the bulb’s specifications.
The same style of warning covers damp locations, dimmers, and timers, photocells or motion sensors.
Porch and outdoor fixtures
Outside, check the damp or wet rating too. A roofed, open porch counts as a damp location; a fixture out in the open, exposed to the weather, is a wet location. If you can’t tell which yours is, choose a wet-rated bulb.
Stay within the fixture’s limit
Enclosed fixtures have a maximum wattage like any other. Compare it with the watts under Energy Used on the bulb’s label, and turn the power off and let the old bulb cool before you change it.
The box wording and the heat facts come from ENERGY STAR (EPA), the bulb ratings from the makers’ own pages, the damp and wet definitions from OSHA’s electrical rules, and the wattage advice from the CPSC and the FTC’s label rule.
