In one exemplary, non-limiting embodiment, the motion is detected via one or more motion sensors. An ambient light level is then determined using one or more ambient light sensors, and a light control device causes light to be output at an output light level associated with the determined ambient light level. In one embodiment, the output light level is further determined based on a current time interval during with which the motion is detected. ## Claims ### Claim 1 A method for dynamically adjusting output light levels, the method comprising: determining, in response to motion being detected by at least one motion sensor, an ambient light level within a local environment using at least one ambient light sensor; determining a first output light level and a second output light level stored within memory, wherein the first and second output light levels are associated with the ambient light level that was determined in response to the motion being detected; determining that the first output light level is associated with a first time interval, and that the second output light level is associated with a second time interval; determining that the motion was detected at an occurrence within the first time interval; selecting the first output light level in response to determining the ambient light level and determining that the motion was detected at the occurrence; and causing, using a light control device, light to be output at the selected first output light level. ### Claim at position 2 2-6.
