Osram presents 57 W CFL
At the Frankfurt Light and Building Fair, Osram presented a 57W pin-based CFL with a light flux of 4300 lm. This is a very efficient CFL, with a luminous flux of ~75 lm/W excluding ballast. The lamp is very compact, with a total length of 181 mm (197 mm incl. base). Amalgam technology is used, which allows the lamp to keep 90-100% of its light flux in ambient temperatures between 5 and 60¡C.
