SPECS: At a 3000K temperature rating, the Blackout Backup Emergency Bulb is a blend between a traditional soft white (2700-3000K) and a warm white bulb (3000-4000K) providing a slightly warm, yet neutral illumination for indoor and outdoor spaces. The energy-efficient LED uses only 8-watts, making it an ideal replacement for 60-Watt incandescent bulbs and CFL bulbs. It uses 7.5x less energy than a standard 60W incandescent bulb and is 2-3x more efficient than standard 60W replacement CFL bulbs.
