Metal Halide Lamps                                                Mercury Vapor Lamps

This lighting sector includes Mercury, Metal Halide, and Sodium lamp types. All three of these lamp types are extremely popular in area lighting applications. You will find many of these lamp types in parking lots, warehouses, and other large areas where lumenous efficiency is extremely important.

With it’s bright white light, and high color rendering characteristics, Metal Halide is quickly becoming the most popular lamp type in this sector. The arc tube is by far the most critical component in determining the quality of the finished product. There are arc tubes available, which are made in the Orient, and the quality is dreadfully poor. Di*Star Metal Halide lamps    are manufactured with a high quality domestically made arc tube which rivals the quality of  HID lamps made by GE, Osram, and Philips.

High Pressure Sodium lamps are also very popular. Their color rendering characteristics are very poor, but their extremely high lumenous efficiency makes them a good choice for large areas that do not require high color rendering, such as parking lots and street lighting. Di*Star high pressure sodium lamps also incorporate a very high quality arc tube, to create a high lumenous efficiency, and consistent quality from one lamp to the next.

Mercury lamps are the most inexpensive to make, and pricing pressures have rendered this the area where the shoddiest lamp quality is found. Our Di*Star mercury lamp series is made with  the same quality components as the rest of our HID series, offering customers a consistently solid product at a very affordable price.
