lighting for my 50???

First of all, I think it's a load of s*** it we have to tip toe around these parts and not discuss certain things because certain vendors don't sell those products or it's being sold by a competitor. Granted, they do support the forums but we are all here to discuss the hobby and help each other out, not discuss what the vendors are selling. Sorry, I've seen it happen a few times around here are it bugs the hell out of me... Sorry, needed to vent.

About your lights... Personally I'd go with the Odyssea (though I can't say for sure without knowing what dorothy is); I considered this same unit at one point. The 250W will give you more options down the road with what you can keep and the power compacts actually aren't all that bad if you're just supplimenting a halide (which can even be avoided if you want to use a high colour temperature bulb). My Coralife Aqualight Pro (not bought from any of the vendors here) uses this same sort of MH/PC set-up and it's stellar.

Also, there are some tricks you can use to make an Odyssea cool. Google 'em or we can discuss them here.
