LED bright stik illuminates spaces with cool, bluish-white light instantly. Its sleek cylindrical shape fits in place of a traditional 100-watt incandescent bulb-and some sockets where a CFL doesn't fit. Replace a 100-watt incandescent with an LED bright stik and save around $13 on energy costs each year. And keep saving for the next 13 years. That's a long time you can spend not worrying about light bulbs.
