some quotes;

Figure 6 shows a comparison of the spectral outputs of all the highest output combinations of the AquaMaxx lamps and the ballasts used for testing. From the spectral plots at first glance it seems that the spectral output of these lamps shows similar characteristics of the lamps sold in the hobby with the "20000K" label.

Given that the spectral plots look very similar to the blue ("20000K") lamps, the 400W AquaMaxx was compared to a Radium 400W - both running on a PFO HQI ballast. Figure 7 shows the spectral plots of the 2 lamps - and as is clearly obvious the output is almost identical to that of the Radium along with very similar PPFD values (142.8 for the Aquamax and 147 for the Radium). This lamp would make an excellent substitute for those that are currently running Radium lamps and at a significantly reduced cost.

Marine Depot has them on sale until the end of the month at 33 % off.

I may be wrong but I thought Russ ran these. I thought there was something he didn't care for with them. Hopefully he will chime in let us know his opinion.

I have heard from several people that they become drastically less blue after 6 months of use.

After 2 months, my 400s shifted color and lost most of the blue. They were nice when I first fired them up.

you get what you pay for right? I think we have all learned this in the hobby.....well most of us ;)
