GE Lighting 400 W Metal Halide Lamp

This 400 W metal halide lamp uses a mogul screw (E39) base and an ED28 glass envelope. It delivers 38,000 lumens at a 4100 K colour temperature with a CRI of 65. The rated life is 20,000 hours under ANSI codes M135/M155.

Horizontal Burn Position Only

The bulb is designed for horizontal operation within a tolerance of 15 degrees. It is suitable for enclosed fixtures that accept this orientation and wattage. Buyers needing vertical or universal burning positions should select a different lamp.

ANSI Code M135/M155 Compatibility

The lamp carries ANSI codes M135 and M155, which define its electrical characteristics for ballast matching. Verify that the existing ballast lists one of these codes before installation. Using an incompatible ballast will prevent proper starting and reduce lamp life.

Questions about this item

How do I install the MVR400/HOR/ED28/PA bulb in a mogul screw socket?

Screw the E39 base into a mogul socket rated for 400 W metal halide and ensure the lamp operates within fifteen degrees of horizontal to meet the 20,000 hour rated life.

What maintenance will this 400 W metal halide lamp require over time?

The lamp is not shatter-resistant and has a 20,000 hour rated life; plan to replace the bulb once output drops or at end of life, and clean the clear glass envelope if dust reduces the 38,000 lumen output.

What is the first limit that appears when this lamp runs continuously in an enclosed fixture?

The lamp is rated for enclosed fixtures and a horizontal operating position within fifteen degrees; exceeding that tilt angle is the first limit that reduces the 20,000 hour rated life.
