Product Review: Spectral Analysis of 250W Metal Halide Lamps: Giesemann, Krystal Star, South Pacific Sunlight, BLV, Phoenix Electric Company

Sanjay discusses the results of additional bulb and ballast testing.
By Sanjay Joshi, Ph.D.

Since the last report on 250W metal halide lamps, I have received several new lamps. These 7 new mogul base lamps and 4 double ended lamps were evaluated with 6 ballasts used to drive these lamps. The lamps are listed in Table 1. As usual these lamps were tested using the identical setup to all my previous tests, thus allowing for direct comparison between the lamps.
