Need to replace those old fluorescent bulbs? This SATZOL 4-pack of 13W GX23 2-pin compact fluorescent bulbs has got you covered! These are perfect replacements for Sylvania CF13DS/827/ECO, Philips PL-S 13W/827/2P/ALTO, GE F13BX/827/ECO, and Plusrite CFT13W/GX23/827 models - so if you've got fixtures that take any of those, these will work perfectly. They put out 800 lumens of warm, comfortable 2700K light that's easy on the eyes and creates a cozy atmosphere. With a color rendering index of 80 CRI, colors look natural and true to life under these bulbs. The GX23 2-pin base makes installation super simple - just push and twist into compatible fixtures. Each bulb measures about 7 inches tall by 1.2 inches wide, so they'll fit most standard compact fluorescent fixtures without issues. The real win here is the longevity - these bulbs are rated for up to 10,000 hours of use, meaning you won't be changing them out every few months. Whether you're using them in home offices, workshops, garages, or commercial spaces, these energy-efficient bulbs will save you money on your electricity bill while providing reliable, consistent lighting. Buying in this 4-pack means you've got spares on hand when other bulbs eventually burn out. It's always smart to have extras around!
