Product Review: Spectral Analysis of 400 Watt Mogul Metal Halide Lamps: Ushio 14000K, Icecap 400W Series, Elios 10000K

by Sanjay Joshi | Oct 15, 2008 | 0 comments

Over the last year, I have continued to test the metal halide lamps, for their performance and spectral output. This article presents the last of the 400W mogul lamps tested. Table 1 shows the complete list of the 400W Mogul lamps and ballast combinations tested. Icecap has introduced their new series of lamps, and results of these are reported here. The Elios lamp was one given to me by Italian aquarists, I have not seen this lamp being sold in the USA. While performing tests on the Elios lamp, I also received the new Sunlight Supply Galaxy 400W Electronic ballast, and tested the Elios lamp with this ballast. During the course of this round of testing, the Coralvue Electronic ballast failed and hence was unavailable for use with the Icecap and Elios lamps.

Comparison of Lamp Performance Under Different Ballasts

This section presents the results of testing the different lamps using different ballasts. For each lamp tested different ballasts were used to fire the lamp and data is presented.

Elios 400W 10000K Mogul

The Elios lamp was one given to my by Italian aquarists during my visit to Germany last year. The lamp comes with the technical specifications and relative spectral plot on the packaging – this is something not seen with any other lamp. Figure 5, show the packaging for the Elios lamp. Further information about this lamp can be found at www.reefline.it

Discussion and Conclusion

Figure 7 and Tables 7,8, and 9 show the comparison of the PPFD output of these lamps against all the previously tested 400W lamp/ballast combinations. As seen from the data, the Elios lamp ranks towards the top of the list in terms of output. The Icecap 10000K lamp also has output comparable to the top 1/3^rd of the lamp ballast combinations. The Icecap 14000K has the highest output of all 14000K rated lamps, but the CCT of this lamp is more in line with 10000K lamps. The Ushio 14000K lamp’s output is in the top 1/3^rd of all ballast lamp combinations rated at 14000K. Figure 8 shows how the correlated color temperatures compare to other 400W mogul lamps. The European lamps, Ushio (German) and Elios (Italy) have the color temperature close to what is advertised, with the Elios having the narrowest spread of CCT. The Icecap lamps 10000K and 14000K lamps have their CCT towards the lower end of similarly labeled lamps. The Iccecap 2000K lamp is quite similar to
several of the other 20000K lamps in the market. While testing the Elios lamp I also received the new Sunlight Supply Galaxy 400W Electronic Ballast, and results for this ballast are also presented for the Elios lamp. The Galaxy ballast draws more power than the other electronic ballasts (Icecap, EVC, Blueline) and hence also results in higher output of light. A forthcoming article will review some of the newer electronic ballasts.
