Fluorescent lighting is also significantly more efficient than traditional tungsten, with typically over three times the light output for the same power consumption, although the high voltages required to drive the tubes (compared to that required by LEDs) make mains powering the preferred option. That higher efficiency also makes them much cooler in operation than conventional tungsten lighting. In addition, tubes are available in different colour temperatures, making it easier to match daylight or tungsten lighting without the use of additional light-reducing colour correction filters. At present, fluorescent lighting is a cheaper option than LEDs, and the tubes are relatively cheap and easy to replace should the need arise. For video work, fluorescent light fittings are fitted with high-frequency electronic ballasts, to reduce weight and avoid the audible buzzing that mechanical ballasts can emit and, crucially, avoid any flicker that can occur when the light is driven by a frequency close to the effective shutter speed of a film or video camera.
Some, but not all, electronic ballasts on fluorescent lights include dimming controls, but it is possible to replace non-dimming ballasts with versions that include a dimming option.
