Spectral
Analysis of 250W Mogul base Metal Halide Lamps - PART I
250W
mogul base metal halide lamps have been an ignored set for a
while, with only a few limited choices in the past. Recently
there is a much larger variety of 250W mogul lamps that have
become available and hence there is renewed interest in these
lamps. In an excellent study Joe Burger conducted a detailed
analysis of the PPFD output of these lamps. Details on this
can be found at (http://www.cnidarianreef.com/lamps.cfm). This
set of articles (Part I and II) complements the work of Joe
Burger by providing details on the spectral analysis of these
lamps, along with the PPFD and CCT of these lamps.
Nineteen
250W mogul lamps were tested, using 3 different ballasts as
listed in the table 1. While testing the last set of lamps,
I also received an electronic ballast from Reef Fanatic. Unfortunately,
14 of the lamps had already been returned, and I only had 5
lamps at hand to test with this ballast.
Part
I includes the data for the first 10 of the lamps listed (alphabetically)
in Table 1. Part II will present the data for the remaining
set of lamps along with a comparison of the different lamps.

- only 5 of these lamps were tested with this ballast
The
magnetic ballast used was the Magnetek F-can ballast (ANSI-M58)
and the HQI ballast used was PFO HQI ballast (ANSI M80).
For
each lamp/ballast combination listed, data was collected on
the Spectrum, Photosynthetic Photon flux Density (PPFD) or PAR,
as well as data on the power consumption of the ballasts. The
power consumption was determined using a Vector True RMS power
meter into which the ballast was plugged. The Vector power meter
also records the voltage and current. The test setup used was
the same as previous lamp tests [1], thus allowing for direct
comparison of the results of these lamps with previously tested
lamps [Ref. 1-11].
