It is a photodetector that is used to sense the amount of ambient light present, and appropriately dim the device's screen to match it.
Dimmable integrated helical CFL that dims 2–100%, comparable to standard light bulb dimming properties. Only some CFLs are labeled for dimming control. Using a dimmer with a standard CFL is ineffective and can shorten bulb life and void the warranty. [56] [57] Dimmable CFLs are available.
A dimmer is a device used to vary the average voltage applied to an instrument's lamp. The brightness of a lamp depends on its electric current, which in turn depends on the applied lamp voltage. When the applied voltage is decreased, a lamp's electric current will also decrease, thus reducing the light output from the lamp (dimming it).
Fission power has its critics. Fukushima and the falling prices of renewable sources of power generation haven't made it any easier to operate the large nuclear fleets at Exelon and Duke Energy .
Dimming fluorescent ballasts and dimming LED drivers often use 0–10 V control signals to control dimming functions. In many cases, the dimming range of the power supply or ballast is limited. If the light output can only be dimmed from 100% down to 10%, there must be a switch or relay available to kill power to the system and turn the light ...
