Use these bulbs in standard sockets, panels, and appliances. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Bulbs with a warm light appearance have yellow tones. Bulbs with a neutral light appearance are commonly used in workspaces. Bulbs with a cool or daylight appearance have white/blue tones and are good for inspecting. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.

LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration. Plastic LED bulbs are shatterproof.

With a NEMA 4X rating, these lights resist degradation when exposed to corrosive liquids, withstand liquids sprayed during washdowns, and are dust tight. NEMA 4X is widely considered the standard NEMA rating. These lights are compatible with medium-base, screw-in CFL (compact fluorescent), halogen, incandescent, and LED bulbs (sold separately).

PTFE plastic lenses are impact resistant.

Tempered glass lenses are more durable than plastic lenses; they have a zinc-plated steel guard to protect them.
