The ANSI for this MR16 bulb is ENX. This ENX MR16 from OSRAM operates at 82v, 360w and has 3300k color temperature, 460 lumens, GY5.3 bi pin base, CC-8 filament and average rated life of 75 hours. The optical performance is achieved by the precise faceted reflector that helps soften the beam so that the filament does not project a shadow. The key applications that the ENX is used in are stage, studio and medical equipment. It is a good replacement for the ENX-5 86v 360w bulb.
