Halides: Parallel or perpendicular

[SteelHead]

Ok....wich way is the right way????

 

[Krish]

Depends on the reflector...Which one do you have in mind??

 

[Scooterman]

Most spider types should be perpendicular to the length of the tank, the square types can go either way, & fixtures are designed well parallel , so as Krish asked what do you have?

Also depends on the dimensions of your tank.
