Miniature Light Bulb Changers

Replace hard-to-grip miniature bulbs in equipment such as panels, instruments, indicators, and signs. Install new bulbs without leaving behind oil from your fingers that can cause bulbs to burn out.

Style A are rubber for a good grip on bulbs. Use one end for bulbs between 1/4" and 3/8” dia.; use the other end for 3/4” to 1” dia. bulbs.

Style B have a spring-loaded lever—squeeze the lever to grasp bulbs more securely than style A.

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.

Bulb shape numbers starting with A, G, P, and PS are standard-household, globe-, or pear-shaped light bulbs. E and ED bulbs are often found in high-intensity discharge (HID) lights. ER, PAR, and R bulbs are found in spotlights or floodlights, or recessed can lights.

Style 1 has a slide rod; pull the rod to create a tighter seal than other suction cup changers. Connect up to four add-on poles (sold separately) to extend your reach.

Style 2 includes three bulb changers to cover a wide range of bulb shapes. Connect a twist-lock handle (sold separately) to extend your reach.
