Need to replace some old, burned-out bulbs in your ceiling lights or specific fixtures? This 4-pack from SLEEKLIGHTING is a solid choice. These are compact fluorescent (CFL) bulbs with a spiral shape, and they use a G24Q-1 4-pin base. That's important—make sure your light fixture has that exact socket type before you buy. They're 13 watts but put out a nice 800 lumens of warm white light (2700K color temperature), which is that cozy, yellowish light perfect for living rooms, bedrooms, hallways, and kitchens. They're way more energy-efficient than old incandescent bulbs and have a decent lifespan of over 8,000 hours. Just screw them in (well, plug them in, since it's a pin base), and you're good to go—no rewiring needed. They're a simple, affordable way to keep your place well-lit without a high electric bill. The pack of four is handy so you can replace a few at once or have spares on hand.
