For a general purpose LED light bulb that will match the performance of a standard 40-watt incandescent, the Pharox 400 Tulip is a solid option. It can be used in dimmable light fixtures, and contains no mercury.
The Pharox 400 Tulip uses just 8 watts of electricity, and its 35,000 hour lifespan is equivalent to 25 incandescent bulbs. Its warm white light has a color temperature of 2700 Kelvin, and a color rendering index (CRI) of 88. It’s a great option for general household use, especially in general lighting fixtures that use lower intensity 40-watt bulbs. And the fact that it is compatible with dimmer switches makes it more versatile than some of the LED bulbs on the market.
