I bought a Repti glo UVB tube for my tortoises - we've just adopted them and the light that was in their enclosure looked old and was flickering (but did at least work). I've installed the new one but it won't switch on at all. Have checked all sockets, ensured the fixtures are on securely...it has just baffled me completely. Any ideas as to what I'm doing wrong?
