its not that big of a loss and you still have almost as much light as the hqi with out the heat and have more water volume.might be the difference between you having to get a chiller or not. just my opinion though...
The heat issues assossiated with MH swayed my decision. The room I will be putting the tank into is a south facing room with a south facing window. (My orchids love this room.) Also, an open top tank would help to keep the temperatures down.
