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.

Bi-Pin-Base Floodlight and Spotlight Bulbs

MR16 Bulb Shape

Often used in display and landscape lighting, these small bulbs produce a focused beam of light. Bulbs that are 50W or higher are often used in overhead projectors and microscopes. They’re brightest at the center of their beam angle; the edges of the beam are about half as bright. The narrower the beam, the more concentrated the light.

LED—LED bulbs last longer and are more efficient than halogen bulbs. They generate little heat and withstand vibration.

Plastic Bulb—Plastic LED bulbs are shatterproof.

Dim-to-Warm—Dim-to-warm bulbs mimic halogen bulbs—their light gets warmer as you dim them. They have museum-quality color accuracy, so colors appear as accurate and vibrant as they would in natural sunlight. They’re also flicker free and have lower levels of blue light than standard LEDs to reduce eyestrain.

Bayonet-Base Miniature Light Bulbs


Single Contact, Globe Bulb	Double Contact, Globe Bulb	Small Bayonet Base

Pins on either side of the base lock these bulbs into sockets. These bulbs are sized to fit tight spaces such as indicators and vehicle lights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Incandescent—Incandescent bulbs are traditional light bulbs.

Ultraviolet Disinfecting Light Bulbs

Tubular Bi-Pin Base

Disinfect air, water, and surfaces without chemical cleaners. These light bulbs use shortwave ultraviolet radiation, also called UV-C, to kill viruses and bacteria. They’re often used in surface cleaning lights, air purifiers, and water treatment systems.

Ultraviolet radiation can harm your skin and eyes. For safety, install these bulbs in fixtures with UV protection or wear UV-protective gear while using them.

Rated Life—The length of time these bulbs will effectively kill germs. Replace them after the listed period, even if they still light up.

Cannot Be Sold To—Bulbs cannot be sold to Canada due to import regulations. Those that cannot be sold to outside the United States are due to pesticide regulations.

Four-Pin-Base Plug-In Compact Light Bulbs

Swap out the four-pin base fluorescent bulbs in your fixture or upgrade them to LED. Often used in recessed ceiling lights and wall sconces, these bulbs are comparable to PL, Dulux, and Biax bulbs. Select a light appearance to match your existing lighting. If you’re not sure what temperature you need, choose a bulb with more than one light appearance. You can adjust the temperature with a switch. All bulbs can be used in horizontal or vertical operating positions.

LED—LED bulbs last longer and are more efficient than CFL bulbs. They work with most electronic ballasts, so you can use them in existing fixtures without rewiring the socket. Check if your ballast is compatible by selecting a part number and clicking product detail. To avoid future maintenance, you can also remove the ballast from your fixture and wire the socket directly to the power source.

Replace your fluorescent bulbs or upgrade to LED. These light bulbs are the most common tubular bulbs for fixtures inside plants, warehouses, and offices. Select a light appearance to match your existing lighting. If you’re not sure what temperature you need, choose a bulb with more than one light appearance. You can adjust the temperature with a switch.

LED—LED bulbs last longer and are more efficient than fluorescent bulbs. You can choose bulbs that work with or without a ballast—some bulbs can do both.

Fluorescent—Fluorescent bulbs contain small amounts of mercury. For disposal information, visit www.epa.gov/cfl.

Ballast-Bypass LED—Ballast-bypass bulbs work with sockets that are wired directly to the power source, which cuts down on maintenance. If your fixture has a ballast, you’ll need to remove it.

Ballast Compatible LED— Ballast-compatible bulbs are a quick replacement for fluorescent bulbs, since they work with most instant-start electronic ballasts. Check if your ballast is compatible by selecting a part number and clicking product detail.

Plastic Bulb—Plastic bulbs are shatterproof.
