Philips MHC50/U/MP/4K ELITE 50W Metal Halide

This Philips 50 watt metal halide lamp delivers 4600 lumens at a 4000K cool white colour temperature. It uses a clear ED17P envelope and MasterColor CDM Elite technology for high intensity discharge lighting. The rated life is 20000 hours with a colour rendering index of 86. It suits commercial and outdoor fixtures requiring this specific wattage and base type.

Suits installations needing 50W CDM Elite output

Buyers replacing a 50 watt metal halide lamp in a compatible enclosed fixture will match the original lumen output and colour quality. The 4000K neutral white works well for retail display, area lighting or security applications where colour fidelity matters. Not for buyers who want an LED retrofit, a different wattage, or a lamp for open fixtures without proper enclosure rating. Shoppers needing a screw-base halogen or compact fluorescent should look elsewhere.

Verify fixture rating and ballast compatibility

Before ordering, confirm the luminaire accepts a 50 watt metal halide ED17P lamp with the correct ANSI code. The fixture must be rated for high intensity discharge operation and provide the matching ballast. Check that the enclosure is fully closed if required by the lamp specification. Ensure the supply voltage matches the ballast input. The model number 429944 identifies this exact lamp for cross-reference.
