Constructed with amalgam technology, this TCP 68 watt compact fluorescent spiral light bulb (also called a twisty bulb, curly bulb or spiral bulb) is designed for consistent performance and cooler operating temperatures in any position. With an E39 mogul base socket, these eco-friendly CFL bulbs consume just 68 watts of energy and produce the equivalent light output of a 300 watt incandescent bulb (4,200 lumens). UL Listed and available in a 4100K cool white color temperature, these 277 volt CFL bulbs have a Color Rendering Index (CRI) of 82. Keep in mind that the warm yellowish glow of a traditional incandescent bulb is typically around 2700-3000 Kelvin (K).

These 277V CFL bulbs have a lifespan of 10,000 hours, backed by an 15 month limited warranty. The temperature range for this product is -20 to 160 degrees Fahrenheit, with dimensions of 4.1 inches width and 9.9 inches MOL.

Do NOT use this 68 watt medium base CFL in an open recessed can or any type of enclosed fixture as using the bulb in this type of application will void the warranty.
