Would you be so kind as to tell me on what you base this statement

I have a bell shaped pendant of which I am sure Coralife has sold thousands over the years. It is a MH pendant which originally came supplied with a Coralife 5500K bulb.

In short who says the bulb I have is nor made for vertical use

I am not using the light anymore, because I don't get the ripple effect I got the light for. And the ripple effect is the only reason I would like to use MH light

As far as color and intensity goes I am very happy with the 2X65W PC fixture that is on the tank now.
