It can be made into a ball or a cylinder, power 15 or 13 watts, the shell has two kinds of transparent or translucent. Marathon lamps are about 75% more efficient than standard incandescent lamps and have an average life span of 9,000 hours. In a typical U.S. city, using such lamps saves about $ 45 less than a typical incandescent bulb. The lamp operates at a lower temperature than typical incandescent lamps and can be safely touched without burns, while lower operating temperatures can save up to 23% on air conditioning costs.
