Screw-In Base Floodlight Bulbs
Often used in recessed can fixtures and track lighting, these bulbs produce a focused beam of light. 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 light 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.
PAR bulbs have narrow beam angles that provide more focused beams of light than other floodlights. A short length allows them to fit in small can fixtures without protruding.
LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration. Plastic LED bulbs are shatterproof.
CFL (compact fluorescent) bulbs are more energy efficient and last longer than halogen bulbs. It takes several seconds for them to reach full brightness. They contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl).
Halogen bulbs are energy efficient.
Bulbs that cannot be sold to the listed regions do not meet mercury and/or energy efficiency regulations.

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.
