Feature Article: Spectral Analysis of 250W Mogul base Metal Halide Lamps - PART III: EVC, Happy Reefkeeping, Agromax and Coralvue

By Sanjay Joshi, Ph.D. Posted Apr 14, 2005 08:00 PM Pomacanthus Publications, Inc.
Additional 250 watt lamps on various ballasts are reviewed.

Since the previous articles on 250W single ended mogul based metal halide lamps [1,2], I have received several more 250W SE lamps from EVC, Happy Reefing, and Agromax, and Coralvue.

These 8 new 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.
