Excalibur to Lunar ratio?

[ash-hole!]

Well I sadly haven't brought myself to put up the money for a lunar yet but I have several Excalibur lamps that in recent years have become cloudy. I would rather refill them with Mathmos lava and fluid. So my question is how close is a lunar bottle to an Excalibur? Smaller or larger?

Iike always I appreciate your shared knowledge

and hope you all are doing well and staying safe!

Thanks

Hi.  Can you tell me the dimensions of the Excalibur bottle please?  What is the base diameter and how high in the bottle is the fluid level from the base?
