A common dual dimmer module used in stage lighting A dimmer. A dimmer is a device connected to a light fixture and used to lower the brightness of the light.By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output.
As a practical matter, many 0-10 V dimming control inputs can be operated by replacing the variable control resistor with an electronic switch. When the switch is on, the control voltage is near 0 and the light is fully dim. When the switch is off, the control voltage is maximum and the light is fully bright.
One of the husband's tricks is to secretly dim and brighten the indoor gas lighting, insisting his wife is imagining it. [10] The gerund form gaslighting does not appear in the play or films. [10] It was first used in the 1950s, particularly in the episode of The Burns and Allen Show.
Consistent light exposure has a greater effect than intermittent exposure. [14] In rats, constant light eventually disrupts the cycle to the point that memory and stress coping may be impaired. [15] The intensity and the wavelength of light influence entrainment. [2] Dim light can affect entrainment relative to darkness. [16]
A ghost light illuminating an empty stage in a darkened theatre. A ghost light is an electric light that is left energised on the stage of a theatre when the theatre is unoccupied and would otherwise be completely dark. It typically consists of an exposed incandescent bulb, CFL lamp, or LED lamp mounted in a wire cage on a portable light stand. [1]

It is a light-sensitive receptor protein that triggers visual phototransduction in rod cells. Rhodopsin mediates dim light vision and thus is extremely sensitive to light. [6] When rhodopsin is exposed to light, it immediately photobleaches. In humans, it is fully regenerated in about 30 minutes, after which the rods are more sensitive. [7]
A daytime running lamp (DRL, also daytime running light) is an automotive lighting and bicycle lighting device on the front of a road going motor vehicle or bicycle. [1] It is automatically switched on when the vehicle's handbrake has been pulled down, when the vehicle is in gear , or when the engine is started, emitting white, yellow , or ...
