How many Radion 15w Pro Gen 4?

[Ert]

Hi all

I want to upgrade my lighting from the current AI to some radion 15w Pro Gen 4. My tank is 4 ft long and 1.5ft wide. I'm thinking either two or three with the goal of SPS dominated.

I was also thinking of the Reef Breed Proton V2 48.

Pls chime in

You can start out with two but I would say you would need three after a while to deal with shadowing issues as your corals grow in.

3 XR 15's or 2 XR30's

Would the xr15 be able to cover a tank 24" wide? I was considering 3 for a tank 48"x 24"x18"

It's supposed to be able to cover that width. The recommended width of coverage is 18" however.

I've seen more than just a couple plan on a XR15 covering a 24" x 24" area.
But if memory serves me right, isn't that what ETM claimed was the coverage area of the gen1 XR30?

My tank is 48" x 18" so 2 15w pros should cover it. I'm thinking of starting with two and then adding another.
In addition, should I go with the reeflink or the XRM module or my APEX?

Or how about

3 15watt gen 4 pro vs 2 30watt gen 4 non-pro??

IMO a minimum of 3 XR15s I have 3 XR30 pros on my 4'6" SPS dominated tank.I went from 1 x XR30 and 2xXR15s to 3xXR30s

I have 3 xr15s over my lowboy (48x24x10) works perfectly!

On xr15. If rim less I will do 3. If has bracket I will use 4.
My 120 4x2. I use 4 too reduce shadow.

Here is a pic of tank. This way u get a id with 4 xr15 on ab+ lab. 45% pic shows 45 min before turn off light

Start with 2. You will most likely end up with 3.
