Hi,
I'm looking at replacing my existing lighting with two light bars.
My external tank measurement is 91cm and I have a wooden hood which sits on the top (& can be lifted off)
The hood has an opening of 83 cm. I was hoping to use z holders to mount the lights and place the hood on top.(I have about 7cm space in the hood.

Firstly I as looking at the 90 cm light bar with Z holders. I understand the light bar is actually shorter that 90cm? Or is 80cm light bar better?

Secondly I was looking at using a actinic & deep actinic. Can these be mixed and still controlled together ? Eg light intensity & mix of colours?

Many thanks Brett.
