    MR11 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.

    Four-Pin-Base Plug-In Compact Light Bulbs

    Image of Product. Back orientation. Light Bulbs. 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.
    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.
