If something is to be reduced then there must be a reducing agent present. Also if something is oxidized then there must be an oxidizing agent present. You must have a reducing agent or oxidizing agent present in order for a redox reaction to take place. An element can't just dislocate it's electrons. There must be an outside force present in order to do that.
I was looking at another rack light then I found the Furman RL-LED which was much cheaper and it has a dimmer. Markertek matched a competitor's price so it was a no brainer. The Furman is built to last, fits perfectly in my DJ coffin case and uses very little power. The light is more than bright enough for my needs.
This sturdy unit mount conveniently into one 19 rack space providing light from two gooseneck LEDs. A dimmer switch on the front panel allows you to easily adjust the light to exactly the amount desired. The RL-LED is powered by a detachable 6' cord with an enclosed 12 VAC power supply inside the AC plug (wall wart).
