Halogen MR16 for professional fixtures

The Ushio 1000311 is a 120 watt halogen lamp built to the MR16 form factor with a GX5.3 base. It delivers a 3200K colour temperature suited to stage, studio and display lighting where consistent output matters. The rated life is 120 hours at full power.

GX5.3 base and 17.7 volt operation

The two-pin GX5.3 connector fits standard MR16 sockets without adapters. Operating at 17.7 volts, the lamp requires a compatible low-voltage transformer or power supply matched to its 120 watt draw. The compact reflector design directs light efficiently in track or recessed housings.

Replaces legacy EKN-coded MR16 lamps

This model carries the ANSI EKN code, making it a direct drop-in for older halogen MR16s carrying the same designation. The upgrade is worthwhile when a fixture demands the exact 120 watt, 3200K specification and the 120-hour rated life meets the maintenance schedule.
