Japan's Mitsubishi Corporation introduced a new type B fluorescent lamp. The lamp consists of four fluorescent tubes that are placed together and are shaped like a "B". Its luminous efficiency is high. The 27-watt fluorescent lamp has the brightness equivalent to a 100-watt incandescent lamp, and its power consumption and heat generation are 1/3, and its service life is six times.
