Hey there, need to switch up your lighting but stuck with different socket types? No worries! This 3-pack of B22 to E27 light bulb converters lets you use screw-type bulbs (like E27) in bayonet sockets (B22) super easily. Perfect for LED, CFL, or old-school incandescent bulbs—so you can finally use those energy-efficient LEDs you've been wanting to try! Each adapter is made from a mix of metal and heat-resistant plastic, so it's sturdy and safe. They handle up to 200W and 0-250V, with decent heat resistance too. Installation? A total breeze. Just plug your B22 bulb into the adapter and screw the whole thing into an E27 socket. No tools, no fuss. Great for updating home lighting, office lamps, display cases, under-cabinet lights, or even commercial spots. They come in a simple white finish that blends in nicely. Just a quick heads-up: always double-check your bulb voltage and if you're unsure, maybe chat with an electrician. But honestly, these little adapters are a game-changer for making your lighting setup way more flexible. Grab a pack and light up your space your way!
