One thing I've mentioned when the lighting debate came up recently is that the manufacturers of bulbs change. What may be a quality bulb one year may not be the next. AB has switched a few times as has Coralife. I can't find my reference but it is somewhere on Fishnet and a point is made by Richard Harker that sums it up well.

As for prices, they are seeming to be a lot better. Enough so that I considered buying new MH ballasts so that I can switch bulbs if I want. But, the longevity of the Iwasaki is still one of it's best features. 109 bucks for over a year compared to $180 for 6-9 months. Basically the cost of the higher K bulb is $360. That is a lot of scratch per year.
