About lights: I have in the present hill stream tank 4 80W T5 lights (everything is 220V here). Then I have got some small lights (12W) for a slow start of the morning and a slow end of the day (poor manīs dimming system
). Apart from that a couple of hours a 40W heating lamp and a UV emitting light for the lizards.
I my other viv there are 2 80W T5 lights and a couple of 36W PL lights.
I plan to use all of these as well as two 70W spotlights to add some atmosphere in the evenings (with the 80W lights out).
