    Standard

    Bulb

    Your go-to bulbs for everyday use in standard sockets.
    Use the light appearance to match older bulbs in your facility.
    Warm (3,000 K)—A 3,000K (warm) light appearance resembles halogen bulbs.
    Plastic Bulb—Plastic bulbs are shatterproof.
    App Controlled—App-controlled bulbs offer the most flexibility: a free Wi-Fi app dials in any white temperature or color, toggles power, and runs schedules.
    Selectable Light Appearance—If you aren't sure what you need, pick a bulb with a selectable light appearance.

    Suction-Cup

    Grip

    Swap out hard-to-reach light bulbs without a ladder. For a long reach, attach these to most standard extension poles, such as those used for painting, or to our extension handle (sold separately), which adjusts up to 18 ft.
    Spring-Loaded Grip—Flexible fingers slide over and firmly grip exposed light bulbs. These spring-loaded changers need 1/4" clearance around the bulb, so they won’t work with recessed fixtures where the bulb sits flush or below the trim.
    Suction-Cup Grip—Suction cups attach to the face of the bulb to create a secure vacuum seal. These changers are often used to swap bulbs in recessed lights where there's no room to reach around the bulbs. They include three cup sizes to handle a wide range of bulb shapes, including spotlights and floodlights frequently used in recessed can lights.
