mars light

I purchased a mars light from miniatronics last weekend and throughout the week the light required more and more power to function, until eventually something on the circuit board failed and the system shorted out. What I would like to know is has anybody else had luck with mars lights (HO scale), and if so which ones worked good for you. I am going to call miniatronics Monday and see if they can help, does anyone have any experience with this company? Any help would be greatly appreciated.

Thanks,

Greg
