Venture Lighting's Energy Master line of retrofit products saves energy by operating on your existing 400 watt M59 ballast. The MPI 360W/BU/EM lamp will consume just 360 watts while producing virtually the same light output as your MH400/U lamp. The high cost of a whole new lighting system or the labor cost of rewiring or installing new wiring is not needed with Energy Master energy saving retrofit lamps. Simply change the lamp and use your existing luminaires and ballasts.

For applications where safety is an issue, Venture Lighting offers open-rated Energy Master 360W MPI (probe start) lamps, which meet NEC (National Electric Code) requirements. The arc tube is enclosed within a quartz shroud to prevent the outer glass jacket from breaking in the event of an arc tube rupture, passing ANSI containment tests. Lamp types are intended primarily for open-rated fixtures and provide an added measure of safety in enclosed fixtures.

The MPI360W/BU/EM (38029) 360 Watt M165(59)/O Metal Halide Bulb by Venture Lighting boasts a cool white color temperature of 4000K and an output of 36,000 lumens. With a Base Up (BU) burn position and an EX39 Mogul Extended base, this clear BT37 bulb uses ANSI type M165/O and intended for open fixtures but is suitable for enclosed fixtures. The 360 watt light has an impressive average rated life of 20,000 hours when used in the Base Up (BU) position.
