Physics:Overdriven fluorescent light
Overdriving a fluorescent lamp is a method of getting more light from each tube than is obtained under rated conditions. ODNO (Overdriven Normal Output) fluorescent tubes are generally used when there isn't enough room to put in more bulbs to increase the light. The method is effective, but generates some additional issues. This technique has become popular among aquatic gardeners as a cost-effective way to add more light to their aquariums. While power compact fluorescent lights cost upwards of $60–100 in the US, a twin bulb overdriven lamp can be set up for $30.
Overdriving is done by rewiring lamp fixtures to increase lamp current; however, lamp life is reduced, and modifications of factory lamp wiring void all safety approvals such as UL or CSA.
