A processing device can digitally control lighting fixtures by receiving a request to generate light at a correlated color temperature (CCT) level in an environment. The environment can include a first lighting fixture having a first range of generatable CCT values and a second lighting fixture having a second range of generatable CCT values. The processing device can determine a first CCT value based on the request and the first range. The processing device can further determine a second CCT value based on the first CCT value and the second range. The processing device can further transmit a first digital signal to the first lighting fixture to cause the first lighting fixture to generate light at the first CCT value. The processing device can further transmit a second digital signal to the second lighting fixture to cause the second lighting fixture to generate light at the second CCT value.

A spark plug includes a metal shell, an insulator, a center electrode, and a ground electrode. At least one of the center electrode and the ground electrode includes a projection having a columnar shape. The projection projects toward the other of the center electrode and the ground electrode and forms the discharge gap. A portion of a side surface of the projection has a recess. A melted portion is formed by melting the noble metal tip and an electrode base material. The recess is formed in the melted portion. When D is a depth of the recess from a side surface of the noble metal tip and R is a diameter of the noble metal tip, 0.05 mmD0.3R is satisfied.

An LED lamp for producing biologically-adjusted light output comprising a base, a housing attached to the base, a drive circuit configured to electrically couple to a power source, and a plurality of LEDs. The drive circuit is configured to operate the plurality of LEDs such that a peak blue output intensity level, in a visible spectral output range of between 380 nm and 485 nm is between 0% and 10% of a relative spectral power of any other peaks in the visible spectral output above 485 nm.

A security light system includes a plurality of light fixtures, whereby each light fixture has a light module including an infrared light and an LED that generates white light. Each light fixture includes a driver circuit for controlling operation of the infrared light and the LED. The system includes a light intensity controller for communicating with each light fixture. The light intensity controller includes a control element that enables an operator to selectively increase and decrease the intensity level of the infrared and white light generated by the infrared light and the LED.
