Type of/find MH bulbs ?

[Delphinus]

What lights have you tried and what ballasts are you running? I find that the range of answers to this really runs the gamut because what one person likes may not appeal to another and even the same lights run on different ballasts can have different effects. Think Radiums run on probe starts versus pulse starts versus overdriven on HQI ballasts.

Although my big tank isn't setup yet, I am planning to run 400W Radiums on HQI ballasts. I have the ballasts, I have the lights and I have Lumenarc reflectors so it's all ready to go (I just don't have the basement ready for the tank). This look of Radiums-on-HQI is really one of my favourite looks for a tank but it seems to me it's no longer in favour by many. I'm not sure why that is, is it a cost issue or are Radiums simply a little outdated nowadays?
