The high color temperature causes this bulb to emit a soft, warm light that creates a welcoming and calm environment. It has a luminous flux of 1000 which is equivalent to an incandescent bulb of over 60 watts! This model fits in various mounted fixtures and is perfectly suited for general purpose lighting within your home, office, and any other indoor application. This bulb is florescent meaning it uses 75% less energy and can last up to 10 times longer than incandescent bulbs. It is an ideal replacement for strip lighting as well as the less efficient incandescent light bulb. Not only does the Circline Florescent Light Bulb have a unique and modern C-T9 circle shape but it also saves you money, energy, time, and the environment.
