30" arcadia d3+ 12% uv tube & matching reflector (make sure your starter is powerfull enough for the tube).
Depends on how warm your house is, i've got a 75w bulb in mine. Maybe start with a 40w and see what temps you get and move to a bigger wattage if needed. Ditch the ceramic and just go for a spot.
Either a microclimate (£34ish) or habistat - dimmer stat (£43ish). I've got a microclimate one.
