This video shows the effect of voltage change on efficient electronic ballast fluorescent lighting. Most users of T5 and T8 tubes know that changing their old magnetic ballast fluorescent lighting for electronic ballast lighting saves money on power and replacement costs. However, there is a misconception that these types of efficient lighting cannot benefit from power optimisation. This video shows that this view is incorrect.

I converted an old PW caboose to LED lighting to get rid of any flicker going over dirty track or turnouts. I also wanted constant lighting at all speeds and voltages without the caboose looking like a traveling lighthouse beacon. I also wanted to make sure no heat was generated inside the caboose and all components were cool to the touch. I have successfully accomplished all my goals with this conversion. Alternatively, I could have also incorporated an voltage regulator and increased the LED brightness with smaller resistors while maintaining the fade, but this was the simplest design. and has fewer components.

DMX 12-24v Lighting Controller with manual control mounted in a military case with bulkhead or chasy mount style connectors. Manual control circut switch is intigrated into the "pluging it in" so theres no switch to break. You plug it in it powers the voltage regulator on to give proper voltage to go through the pot and then returned for the analogue control. This is just a prototype there will be future revisions such as making it better looking inside mabe even multiple units in a larger housing weel see where it goes. Special thanks to Vance Vegas and ADlight and Special Effects for the work.
