OSRAM 93506 ENH 250 W 120 V – MR16 halogen lamp with dichroic reflector (GY5.3) for projection and instrumentation (3150 K · 175 h)
The OSRAM 93506 (ANSI ENH) is a precision halogen lamp with an MR16 dichroic reflector and GY5.3 base, designed for projection equipment, medical fiber optics, instrumentation, and compact stage lighting fixtures . It offers a color temperature of 3150 K , a CRI of 100 , and a nominal luminous flux of 340 lm measured at the reflector's optical system. Its precise filament-reflector alignment and 152.5 mm focal length ensure a focused and stable beam. The series includes HLX (XENOPHOT) variants with xenon gas instead of krypton, providing up to 10% more luminous flux at the same wattage. It is dimmable and maintains virtually constant performance throughout its rated life of 175 hours .
