The clean-air Lotus Vaporizer should be used with a goose-neck style torch lighter. The more common straight-necked torch lighters don't work well with the Lotus because they would have to be used in an upside down position and not operate reliably. The Lotus Vaporizer could be used on its side with a straight-necked torch lighter but you would see the top of the Lotus Vaporizer with only one eye and lose depth perception. While this configuration would work, we don't recommend it.
A standard yellow flame cigarette lighter does not produce enough heat for the vapor cap to work properly. Additionally, when the flame hits the 'hot plate', a large amount of soot is left behind.
