120 tir?

[SnowManSnow]

I'm slowly changing out my LEDS to G3 xr30w

My tank is only 16" deep.
I can hang the lights up to 19"

Would you recommend the TIR LENS conversion ?

Eventually I will have 2 radions over the tank

Now I will have a center radion and 2 other fixtures on the side.

Thank you for any help

Here's a pic to help

Again... I'm replacing the center light for now

At that high up you prob will not "need" the 120* lenses.

How long is the tank?

You might just need 1 light over that thing with what I'm seeing.

The tank is 48 long 24 wide and 16 deep

Yeah, you'll want 2 of them to cover 48"
