Hey Steve. Are you using Firefox or Mozilla or using a MAC? Apparently, the page only works under IE on Windows. If you are using IE, did you select the wattage listbox first?

BTW: Doesn't anyone else besides Brainvat, Steve and myself have a position on this? What about some of the other veterans??? The data shows that SE bulbs are generally brighter. Is the data wrong? Do the graphs lie? Is PAR not a good measure of light output or intensity? What is better than or more relevant to corals than the measure of PAR or PPFD. Are there any links at all with data from research that shows DE's of the same brand are generally brighter than SE's given the same color temp and ballast?

Could people start jumping in and verify that I am not blind here and that the graphs and data on the website do indeed indicate that the SE's tested had higher light output than their DE counterparts? Am I out to lunch cause everyone else is awfully quiet. I am constantly rechecking the data and graphs thinking that I am reading it wrong since someone keeps telling me that the DE's are brighter based on the data on that website.
