The flicker controller has been designed to simulate a candle - oil lamp in a drafty room. We have to simulate under these conditions as without the draft the candle - oil lamp would never flicker and would look like any other bulb in your dolls house or model layout To achieve this flicker affect we have had to use some artistic license, The results are however quite stunning. The video clip below is our candle - oil lamp flicker effects controller "IN ACTION" The clip was vidoed using our CF6LP candle flicker effects controller as below.
