Crestworth Astro Bulb types

[Mark]

Hi
I have an original Crestworth Astro and an Astro Mini (and once I pick it up on saturday an Astro Lantern), all bought second hand without bulbs. Can anyone tell me the exact bulb type these require?
They have SBC fittings, but I can't find anywhere that specifies the bulb type.
Thanks

Thanks, for the welcome and the reply!

I have 1 more question (well only 1 for now :) ). Does anyone know the best place to get refills in the UK?
I looked at the Mathmos ones, but it was a sealed bottle. My Astro has the bottle top as part of the cap so I can't just swap them. I'm guessing I could just break open the Mathmos refill, but is there a better option?

My Astro has a felt base with 5 feet, I understand from your site that's a gen 4 and uses a different bottle to the modern Astro?
My Mini has a black base so hopefully I can just replace the bottle on that one.

Can you confirm the Astro Mini should run on a 25/30W bulb? I can't get mine to flow at less than 40W
