I haven't really been following the topic of Dana Riddle's "potential point of diminishing returns" for lighting intensity. It seems to me that from reading this article here, there may be some issues with those findings?

DJ88, why go with the Sunbursts over the Radiums? Do you want to stay in the 250W range perhaps?

I wonder how it would be best to mount differing bulbs over the footprint shape of a typical tank, without getting differing colour zones. It's almost like more of us should get those lighting tracks for hydroponics (I know some people do this already). This way, even though we may stil get the "zones", no one place in the tank gets a disproportionate amount of one over the other?
