Radion xr15 blue G5

[LagoonLounge]

Hi Reefers,

I currently have a red sea nano peninsula 100L, i currently have a reef factory reef flare pro blue medium on the tank.

I have 2 xr15s blue i thinking about putting one on the nano peninsula ( Removing the reef factory light ), my only concern is PAR... I'm currently getting just over 400 par ontop of the rockscape.. but i really like the colour the radion g5 produces..

Tanks is mainly sps dominant with a few gonipora's and 2 torches..

Any help would be great

I do apologize, but I'm not sure what your question is.

Basically is the par on a single xr15 blue g5 rubbish and would one xr15 blue g5 grow and colour acropora's in a 100L nano peninsula?

The XR15s are meant for smaller tanks. Your 100L is about 26 gallons which, one XR15 should cover if you have it pretty much maxed out. Do you have a PAR meter?

I can get one from a friend. Would a high intensity lens be better

Optimize Your Radion: The Right Lens Kit for Every Aquarium

Ideal for Deep Aquariums or High Radion Mounting
Higher PAR, Narrower Focus

You can " focus" what you have by changing ( lowering) height.

45x45x58.5cm tank dimensions.
Say 18 x 24 x 18 deep


G4 80 degrees
High intensity lens 86 degrees
G6 126 degrees
G5 108-117

So with the current lens math point to a height of about 6" -7.2" (108- 117degrees)
Any higher and you start losing light outside the tank.
Lower and you start losing surface coverage but increase intensity at substrate.


High intensity lens height is about 10.7"
Any higher and you start losing light outside the tank.
Lower and you start losing surface coverage but increase intensity at substrate.


Calculations are based on a rough led panel (not fixture) of 3" x 4.7" using 4.7" and 24" .
Obviously a lot of slop in this but it gets you a picture of what you are asking for.

If your lights higher than say 7" lowering it is cheaper than a new lens.
If you can't lower it then a new lens is fine if you can get it up to about 10"
Lower than 10" will increase substrate par at the cost of less surface area coverage.

So "better " is relative to a bunch of "ifs".

The "official" height.

AI Overview


The optimal mounting height for a Radion G5 LED light fixture is generally recommended to be between 8 and 10 inches above the water surface.

I'd argue (well I just did) that their recommended height is a wee bit optimistic..

AI Overview


For a 24" cube aquarium, a Radion G5 XR15 mounting height of 9 inches above the water surface is generally recommended. This height allows for a good balance between PAR penetration and coverage, ensuring corals receive sufficient light
