It looks like a light bulb, it can even screw in like a light bulb…however, IT IS NOT A LIGHTBULB! Use our Global Warming Candle for light instead and save the planet! It saves you all the energy that is wasted with electricity and allows you to have the same, if not better, light with a candle! All you need is a matchstick! The candle bulb is white and has a standard metal base at the end like a regular light bulb! 5 hour burning time.
