(Pack of 4) 13-Watt Single Tube 2 Pin GX23 (see photos) Base - 3500K Neutral White 35K CFL Light Bulb - Replacement for Sylvania 20335/21137 CF13DS/835- Philips 146845 PL-S 13W/835 GE 97569F13BX/835

These KOR compact fluorescent plug-in bulbs are a solid choice for anyone needing reliable lighting replacements. The 4100K cool white color temperature provides a bright and clean light that works great for workspaces, kitchens, and utility rooms. At 13 watts, they’re energy-efficient while still giving off plenty of illumination. I found installation to be quick and easy thanks to the 2-pin GX23 base. They’re also well-packaged, so all four arrived without any damage. The quality feels consistent and each bulb lights up instantly with no flicker. Overall, a great value for a 4-pack of dependable fluorescent bulbs.

Good bright lighting, good quality

Worked great for my application Nice bright white light

These are great lights. They fit perfectly. My package was dropped (thrown) on my porch so one of the lights was broken. But overall they are worth purchasing.

Bulbs came neatly packed in individual boxes. Work great!

Fits my old Ott lamp perfectly. The price was excellent, four bulbs will last me a long time. Arrived when it said it would.

The media could not be loaded. I bought this 4-pack of light bulbs in June 2021, and here we are—3 years and 11 months later—one bulb still going strong and two still in the package. The last one? Let’s just say it recently decided to audition for a horror movie by flickering like it was summoning ghosts and making creepy crackling noises like a possessed toaster.The package boldly promises 11 years of life based on 3 hours of use per day. I doubt we even hit that daily quota. So… yeah, not quite living up to the decade-long dream. And let’s be real: a spooky light show and ghostly hum weren’t part of the original sales pitch.On the bright side (pun absolutely intended), the bulbs light up our closet beautifully. The cool white color makes it easy to find mismatched socks and question old fashion choices. Install was a breeze—snug fit, no fuss. Easy peasy lemon squeezy.Would I recommend them? Yes—just don’t expect a long-term commitment. Think of them as that roommate who seems reliable at first… until they flicker out and leave you in the dark, but at least they lasted 4 good years.

Very bright got it to read by works perfectly
