The Color Changing 36 LED light bulb puts out 90 lumens of light. This is equivalent to 5 watts. This is less than a halogen or fluorescent light bulb but it only consumes 5W of power versus 27-50W that are pulled from halogen and fluorescent bulbs. The energy saving feature of the LEDs gives these lights a longer life expectancy. These bulbs have indoor/outdoor applications. They are moisture resistant and water tight. They are great for accent lighting and table lamps. One year full warranty is offered for component failure. Abuse of product voids warranty.
