This controller allows the use of any device or fixture employing ordinary low voltage incandescent lamps or LEDs to simulate the flickering or twinkling illumination given off by candles, oil lamps, or gas lighting. The controller is completely electronic and produce a truly random effect difficult to achieve using traditional approaches that employ multiple square wave generators or ordinary analog timer circuits. It will handle loads to 6 amperes per channel, 30 amperes maximum total. A microcontroller is used to generate a random effect without discernable patterns or repetition cycles seen in other non-random approaches. Therefore a realistic appearing flame effect is achieved. If the bulbs are placed closely together in a fixture, the effect of motion is produced, as if there were flames or fire present. These controllers use efficient switching type circuitry and power dissipation is minimal. Each channel is totally separate with individual random waveforms so no repetition of patterns are produced, nor is there any "chaser" effect , in which the lamps all flicker with the same pattern but with a visually detectable time delay among the bulbs or LEDs. There is no requirement to use all eight channels. An on board DIP switch is provided to adjust the intensity of the flickering effect to achieve desired effects with bulbs or LEDs

This controller can also be used with a number of suitably colored lamps to simulate a fire. Many other applications exist, such as mobile Halloween and Christmas lighting, or in situations where mood lighting or special effects are desired. Use of incandescent lamps may greatly reduce the danger and fire hazards associated with candles and oil lamps, while still producing the same kind of lighting without open flames or danger of fuel spills and toxic fumes. These controllers can operate with 6 volt up to to 42 volt lamps , with up to 6 amperes load per channel. Flicker rate is also adjustable for realistic effects. This controller is also useful in signage, displays, outdoor or automotive applications such as roof mounted light bars, where larger DC loads must be handled and where only battery supplies are available, or where the direct use of AC line voltage is impractical or undesirable. Requires negative grounded power supply. Lamp and LED loads are hot side switched, allowing one side of load to be returned directly to negative supply leads. This allows use of most standard lighting devices and fixtures used for 12V applications.
