Philips 1500W Metal Halide Lamp

The Philips 131623 MH1500/U is a 1500 watt metal halide lamp built for high-output applications. It produces 155000 lumens at a 4000K colour temperature with a CRI of 60. The mogul screw E39 base fits standard industrial sockets. This lamp suits warehouses, sports halls and large outdoor areas needing intense broad illumination.

Sustained Output and Thermal Behaviour

Rated life reaches 3000 hours per the specifications and 6000 hours per the manufacturer highlights when operated in the correct position. The lamp must run vertical base up within fifteen degrees to maintain output and achieve rated life. Output stabilises after a warm-up period typical of high intensity discharge technology. The clear BT56 glass envelope transmits the full 360 degree beam without diffusion.

Build and Mounting Practicalities

The BT56 envelope measures seven inches in diameter with an overall length of fifteen and three-eighths inches. The glass housing is not shatter-resistant, so fixtures must provide appropriate protection. Operation is restricted to enclosed fixtures and the ANSI M48/E code ensures ballast compatibility. The lamp is not dimmable and requires a ballast matched to the 1500 watt rating.

Questions about this item

How much heat does the 1500W metal halide bulb generate during continuous operation?

The 1500W lamp converts most input power into heat, so the fixture must be rated for high-temperature HID operation and ventilated to prevent overheating.

What ballast and fixture does the MH1500/U require to start and run?

It needs an ANSI M48/E ballast, a mogul screw (E39) socket, and an enclosed fixture rated for 1500W metal halide with vertical base-up ±15° orientation.

Will this 4000K, 170000-lumen bulb work in my older E39 high-bay fixtures?

Yes, if the existing fixture accepts an E39 base, is enclosed, and its ballast matches the ANSI M48/E code; otherwise the lamp will not strike or may fail early.
