My Personal Lighting Set-Up
Glad you've decided to take on some of the Arcadia Lights...They're something else, really makes your enclosure look allot nicer! Plus your cham will praise you
And the double hood is great because you can throw in a 6500k grow light.
The fixture you have is perfect. As long as it has a T5-HO ballast you shouldn't have any problems. And the one you picked up, does.
So my only question is, does it only use 22" bulbs? or 24"?.
I'm assuming 22", because my fixture looks the exact same.
I went ahead and bought the zoomed AquaSun T5-HO Double Hood about a week ago. So far so good. (cost me $55 shipped)

If you do decide on the Arcadia lights i'd go with the 22" 6%: (Cost me $48 shipped)

For the grow light, i picked up a Ultra Sun 6500k bulb: (Cost me $16 shipped, But theres allllllot more options to choose from for under $10)

Hope this helps, i did allot of research before buying a new light set up, so far this was the best choice for me. I went with a aquarium hood/light because i figured they'd be somewhat water resistant incase any mist got into the hood.
