Does this chart seem accurate?

When I was looking for T5's a few months ago I was directed to this site and I found it quite helpful for finally making a choice. After cruising around the site a bit I noticed that they seem to sell alot of Hagen products and I started to wonder if they pumped up the Hagen GLO lights on this chart in order to sell more units to neubies like me. What do you think?

Doesn't seem very accurate to me, some of the electrical costs seems to be based on 24-7 usage so realistically it'll be half that at the most. Also the bulb replacement cost is awfully high on some, probably based on replacing bulbs every 6 months which I don't believe is required when using T5s. Once a year is usually perfectly fine, especially if you rotate the ones you replace, for example instead of replacing 4 per year change 2 every 6 months for better stability and less shock. Not sure about the LUX readings but that's not really important anyway and I wouldn't trust it anyway based on the other data on the chart.
