Introduction

In a previous article I presented
the spectral data of 11 175W Metal halide ballasts. This article
continues with the test results of 11 more 175W lamps as measured
using the same basic setup and distances used in all my prior
tests, thus allowing for a direct comparison with previous data
(now available on the web at
http://www.reeflightinginfo.arvixe.com/).

11) Iwasaki 175W Aqua2 14000K Mogul Base

This is a very interesting lamp that will soon be available to
the reef hobby. In all my years of testing lamps, this is the one
lamp that has in fact tested at around 14000K as advertised. It
also has highest PPFD values among all the 175W lamps to go along
with the 14000K CCT, which would make it a very appealing lamp to
those seeing a lamp that truly satisfy the niche of being less
blue than the 20000K and more blue than the 10000K, without
sacrificing light output.
