osram there is light. and there is osram. osram fh fluorescent lamp system t he innovative concept for economical lighting
t he fh system: smaller diameter, greater economy, better design at up to 104 lumen per watt, fh (fluorescent high efficiency) fluorescent lamps have the highest luminous efficacy of any fluorescent lamp and offer therefore the maximum efficiency. the fh system, with a lamp diameter of ?higher luminaire efficiency thanks to less shading and a slimmer lamp ?much smaller luminaire dimensions thanks to smaller lamp diameter ?5 cm shorter lamp for luminaire lengths, therefore compatible with standard ceiling modules ?higher optimum tempera- ture for luminous flux (raised from 25 c to 35 c) for more lumens in the luminaire ?longer service life thanks to minimal loss of luminous flux from the improved lumilux plus phosphor ?gentle energy-saving operation thanks to the cut-off ecg, with dis- connection of the filament heating as soon as the operating temperature is reached m aximum efficiency, minimum dimensions with the fh system from osram, luminaire designers can go in either of two directions: ?max. efficiency within outer dimensions designed for t8/26 mm lamps ?minimum luminaire dimensions, with the same output as t8 luminaires but up to 50% smaller only 16 mm and a cut-off ecg, gives designers free- dom to create innovative lighting concepts with impressive benefits:
