Hi all, just after some advice, I just wanted to check everything in my set up was okay but have read that the lights my beardie currently has are not recommended, he has 2 76cm 25w repti glow bulbs, one 10% UVB and one 2% UVB , I want to change over to the recommended Arcadia tubes (am in the UK) but I'm confused about which one to buy now and if it's just as simple as swapping them over or will I need a different fitting also? Thanks for any help
