This Philips 9 Watt Energy Saver CFL Light Bulb (2-Pack) is an ideal replacement for a 40 watt incandescent A19 light bulb and standard CFL bulbs. Featuring TuffGuard protection, the silicone-covered bulb is soft to the touch and shatter-resistant. If the bulb accidentally breaks inside, the silicone cover provides a safety barrier that contains broken glass, providing peace of mind by keeping your family safe and ensuring no-hassle cleanup. The smaller-sized bulb looks like an incandescent and fits in most fixtures, ideal for use in kitchens, living rooms, dining rooms, offices, family rooms and bedrooms, among other spaces. It has a soft white (2700K) light, similar to incandescent light, creating a relaxing and comfortable atmosphere. This Energy Star-qualified bulb lasts up to seven years and saves you up to $80 in energy costs over its existence. It can be used in open hanging pendants, table/floor lamps, ceiling fans and open or enclosed ceiling/wall fixtures. (E)* means this bulb meets federal minimum efficiency standards.
