About Brightness and Light Appearance

Find the right lumen level to brighten your space. Then, compare the way warm, neutral, and cool lighting affect the appearance of everyday objects.

Screw-In-Base Floodlight and Spotlight Bulbs

Light up large areas or spotlight an object. These bulbs suit recessed cans and outdoor floodlights. Light is brightest at beam center and roughly half as bright at the edges. All are shatterproof plastic.

Use the light appearance to match older bulbs in your facility.

R14 Bulb Shape—Medium (Standard Household) Base (1 1/16" Dia.)

BR and R bulbs cast broad beams, ideal for large can fixtures.

Warm (3,000 K)—A 3,000K (warm) light appearance resembles halogen bulbs.

Selectable Light Appearance—If you aren't sure what you need, pick a bulb with a selectable light appearance.

Heat Lamp Bulbs

R40 Bulb Shape

Keep food warm, speed up drying, or make chilly workstations comfortable. These bulbs radiate infrared heat that penetrates and warms the surfaces they shine on. The higher the wattage, the more warmth they give.

Shatter-Resistant Plastic-Coated Glass Bulb—A plastic coating helps contain glass shards if the bulb breaks.

R40 Bulb Shape—Cast a wide beam to warm large surfaces. They’re often used in hanging heat lamps and other large fixtures. These bulbs are made of blown glass.

Bayonet-Base Floodlight Bulbs

Pins on the base lock these bulbs into sockets to withstand vibration. Often used in recessed can fixtures and track lighting, they produce a focused beam of light. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.

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.
