Screw-In Base Light Bulbs
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.
Incandescent bulbs are traditional light bulbs. Many have been phased out due to governmental energy requirements, but some are still available for special applications.

Light Bulb Guards
The open design of these guards allows heat to dissipate from screw-in light bulbs. Guards open to fit around bulbs and socket collars.
Bulb shape numbers starting with A and PS are standard-household or pear-shaped bulbs; PAR and R bulbs are floodlight bulbs.
Glass-Retaining Light Bulb Guards
A solid lens protects screw-in bulbs and retains glass if the bulb breaks.
Bulb shape numbers starting with A are standard-household bulbs, B are cone-shaped, G are globe-shaped, S are tapered, and T are tubular shaped bulbs.
Suction-Cup Light Bulb Changers
These changers create a vacuum seal against a light bulb. They're often used to change bulbs in recessed lights where there's no room to reach around the bulbs. They include three bulb changers to cover a wide range of bulb shapes. Bulb shape numbers starting with A, G, P, and PS are standard-household, globe-, or pear-shaped light bulbs. PAR, and R bulbs are found in spotlights or floodlights, or recessed can lights.
Connect a twist-lock handle (sold separately) to extend your reach.
