It's easier than ever to switch from the harsh yellow light of high pressure sodium (HPS) to the clear, white light of metal halide (MH). Make the change just by replacing the lamp! Venture's unique White-Lux lamps fit directly into your existing, wattage specific 250, 400 or 1000 watt HPS fixture and are completely compatible with all HPS lighting systems . No need to change ballasts, ignitors or even reposition the socket.

Metal Halide bulbs are a member of the High Intensity Discharge (HID) family of lighting products. Metal Halide bulbs are among the most energy efficient sources of white light available today. These 400 watt metal halide bulbs feature special chemical compounds known as Halides that produce light in most regions of the spectrum.

This is the Venture Lighting White-Lux MH 400W/U/LU (52134) Metal Halide retrofit light bulbs. The MH 400W/U/LU White-Lux operates off of your existing LU400 S51 HPS ballast. Generating a 4000K CCT with a 65 CRI this HPS to MH retrofit offers high efficacy, excellent color rendition, long service life and good lumen maintenance. Because of their numerous advantages, metal halide HID bulbs are used extensively in outdoor applications and in commercial interiors.
