Ive seen a lamp controller on Exo terra site that has a timer on it which will turn the lamp on over a period of 30 mins, stay on for 10,12,15 hours and then turn of over another 30 min period simulating dawn and dusk....aaanyway it houses 2 lamps, does any one know of a similar thing that houses only one lamp, cause i cant find any where on the net

thanks
