LED Bright Stik illuminates spaces with soft, warm light instantly. Its sleek cylindrical shape fits in place of a traditional incandescent bulb—including some sockets where a traditional bulb or CFL doesn’t fit. And, LED Bright Stik performs better than a CFL Spiral bulb: instant full brightness, contains no mercury and is rated to last 50% longer than a 10,000 hour CFL while using 23% less energy to provide 800 lumens.
