I had a large gap in the top too, so it was useful to have a mercury vapour lamp overhead, to one end of the pen. This was recommended by the Tortoise Trust at the time. I'm still a bit confused as to the current thinking on light and heat, but am I right that most people are going for separate heat and UV light now?

Mmmmm you've lost me a bit there Jan, I'm trying to imagine your piece of hardboard and holes and string, but I'm not getting it, interesting tho.
As for a mercury vapour bulb in a small set up, personally I think they can be too hot for small torts in a small set up, I've found this system works better.but I do use MV bulbs for my adults in a bigger set up.
