Okay, so your fridge light went out - been there! This ZHENMING LED bulb is exactly what you need to get your refrigerator brightly lit again. This 4W bulb replaces those older 3.5W models and works with AC 100-265V, so it's compatible with pretty much any home electrical system. The E26 medium base is standard for most refrigerators, but heads up - make sure your fridge takes E26 (26mm/1in) and not E17 (17mm/0.6in) before ordering. The bulb itself is pretty compact at 1.25 inches in diameter and 2.4 inches tall (32mm x 61mm), so it fits perfectly in those tight refrigerator light sockets. With 580 lumens of bright daylight white light at 5000K, you'll actually be able to see what's in the back of your fridge now! The ceramic and PC construction means it dissipates heat well and lasts way longer than old incandescent bulbs. This thing replaces a ton of part numbers including KEI D34L, KEL 3418L, 5304511738, PS12364857, and works with Frigidaire, Kenmore, Electrolux and many other brands. It's not dimmable, but let's be real - who needs to dim their fridge light anyway? The 360-degree beam angle lights up the entire refrigerator interior evenly. Installation is simple - just make sure the power's off, unscrew the old bulb, and screw this one in. It's dustproof and waterproof rated, so it handles the fridge environment perfectly. Seriously, if you're tired of guessing what's in your fridge or freezer, this LED bulb will make your life so much easier. Plus, it uses less energy than older bulbs, so you save a bit on electricity too. One of those simple replacements that just makes sense!
