Need a reliable, energy-efficient light for your workshop, garage, or office? Check out this Sylvania F30T12/CW/RS fluorescent lamp. It’s a 30-watt, cool white bulb with a color temperature of 4200K and a 60 CRI—so it gives off a bright, clear light that’s easy on the eyes. But here’s the cool part: it’s coated with Lumactiv, a special photocatalytic layer that actually helps clean the air while the light is on! Using nanotechnology, it breaks down impurities, so you get cleaner air along with great lighting. Each bulb puts out 2,290 lumens, lasts about 18,000 hours (based on 3-hour start cycles), and fits standard medium bi-pin bases. The bulbs are 36 inches long and 1.5 inches in diameter, and you get two in a pack. Whether you're replacing old tubes or upgrading your space, these Sylvania lamps are a smart, durable choice for both light quality and air freshness.
