For the best grip, use a standard painter’s pole or any pole with an ACME thread design. Must tighten the side screw after securing the twist pole tightly. Warning: Failure to tighten the screw will cause a loose grip and may result in the device detaching from the pole. (POLE NOT INCLUDED!)

Press the “A” button to activate suction and “B” to release. Center the suction cup on the bulb, press gently, and twist counter clockwise to remove. Attach the new bulb, twist clockwise until it lights up, then press “B” to release after 10 seconds. USER ASSISTANCE: Comes with a handheld remote to turn the bulb changer on or off easily.

Changing high ceiling recessed light bulbs can often be frustrating, but the EZX Vacuum-Operated Light Bulb Changer is designed to make the job simple, safe, and efficient. Built with a lightweight design of just 1.26 lb, this reliable tool is easy to handle while still offering strong performance. The device works best with standard bulb types including PAR38, BR30, BR40, and R20. To help buyers select the right option, the compatible bulb shapes are clearly shown in the product images. Please note, suction may not perform well with bulbs that are too small, oversized, textured, dirty, or rusted, as the tool requires a clean and smooth surface to operate correctly. For secure use, the bulb changer features a standard 3/4” ACME thread holder that fits most painter’s poles or any pole with the same design. To ensure the device stays firmly in place, users must tighten the side screw after attaching the pole. Failure to do so may cause the unit to loosen or detach, so this step is very important. The package does not include a pole, giving customers the flexibility to use any standard ACME-threaded pole they already own. The EZX bulb changer is powered by a rechargeable transmitter. Before first use, charge the device for three hours. Please note that the red charging light will not change color when fully charged. To operate, simply press the “A” button to activate suction and “B” to release. Place the suction cup directly on the bulb, press gently, and twist counterclockwise to remove. When installing a new bulb, twist clockwise until it lights up, then press “B” to release after about ten seconds. For added convenience, the device comes with a handheld remote control that eliminates the hassle of cords or strings, along with a wireless transmitter, charging cord, and a 1-year warranty. We strongly recommend referring to the manual for full instructions.
