The arc tube (18) is comprised of a plurality of U-shaped bent bulbs (31) which have an inner tube diameter ranging from 6 to 9 mm and arranged in parallel with one another. Having a bulb height ranging from 50 to 60 mm and a discharge path from 200 to 300 mm long, the arc tube (18) is designed such that the total luminous flux is not less than 700 lm with a lamp efficiency of not less than 60 lm/W when the lamp is lit at the lamp power of 7 to 15 W. An envelope (19) comprising the cover (14) and the globe (17) has a height ranging from 110 to 125 mm, including the height of the base (12).
