Confused about uvb...again

I’m putting a 48x24x24 tank together and I’m not sure about the appropriate height for the uvb. I’m also debating t5 vs t8. From what I’ve read, t5 seems like the better choice for the 24” height. I’m looking at Arcadia 14%. Do I need reflectors on the fixture for it to work the best? And it’s a 24” length on the fixture. Too short? Not enough coverage? Lol, so confusing.
Since this is an upgrade for my 11 month old “Max”, I’m going to go bioactive. Any suggestions? I guess I will need a plant light too! It’s never ending lol.
Any suggestions will be greatly appreciated.

Thanks,
Shannon

I have a viv that size and have a Arcadia 12% bulb that is 12-15 inches above the basking decor. The viv came with a 36" fixture installed, but I think I'd rather have a 24" if I could do it over again. Where it is placed there is at least a good gradient for Sir Henry to move around and choose from. You will want the reflector on the fixture. I do not have experience with bio-active setups though, so someone may have more input for you on that respect.

I cant answer the questions about the bio active light but the Arcadia 14 % is a strong bulb distance on that would be 17-18 inches directly above the basking decor --- the 24" fixture is fine for your tank -- you can also use the T5 as well --- I have used both in my tanks - as mine are 24" high too -- currently I am using the Arcadia 12% bulbs -- which are considered T 5's -- and distance is 12-15 inches -- and yes you want fixtures w/ reflectors ---

I second that about the 14% those are made for large enclosures a 12% with reflector would be better choice my viv is 24 tall and thats what we use
 
I use a 36” as well. When I redo the lighting, I’m going bioactive as well, I’m going to install it on an angle. I also picked up a 36” jungle dawn because that’s what was in stock. I’d probably have went 24” for that but I’ll just angle that too. The 36” does fine in a 48” though. Just make a nice height gradient from hot side to cold side. Angled branch or something.

Edit- I use the 12% as well. 14 is too powerful for interior mount in my viv
