GT-Lite GT-CTB-40A LED Corn Cob Light Bulb: 300W incandescent equivalent brightness
Meet the 5200 Lumen LED Corn Cob Light Bulb from GT-Lite—your new best friend for lighting up spaces, inside or out. It's like swapping your old 300-watt incandescent for something way smarter, giving you 5200 lumens of crisp daylight (5000K) but only sipping 40 watts of power. And thanks to its quirky cone shape, light goes everywhere, which is just what you need in garages, warehouses, or that DIY project you've been putting off.
Why you'll love it:
- First off, it's a energy-saving ninja, cutting your energy use by nearly half compared to those old-school bulbs.
- Then there's the long lifespan—25,000 hours! That's over 22 years if you're using it 3 hours a day. (Talk about a long-term relationship.)
- Built tough with aluminum and plastic, plus a protective shield, because bumps happen.
- And, oh, installation is a breeze—just screw it into any standard E26 base. No fuss, no muss.
- Energy saving with 40-watt usage
- Long-lasting 25,000-hour lifespan
- Special cone shape for wide light spread
- Easy to install with E26 base
- 300W incandescent equivalent brightness
