Also known as jelly jar lights, these lights are sealed to keep out humidity and dripping, splashing, and falling liquids. All are UL listed for wet locations. These lights have a heat-resistant lens. For impact protection, they have either a guard or a polycarbonate lens.

Lights with built-in LEDs have a frosted glass lens that reduces glare and protects against dust, damage, and scratches. They cast a neutral light often found in workspaces.
