Selecting your light 'Colour'Light temperature (colour) is measured in Kelvin (K). The lower the number, the warmer the light. 2700K is like the light from an old-fashioned bulb. 3000K is less warm, and then as you go up the light becomes cooler and whiter – anything approaching 5000k will be nearly blue. Sometimes these are called ‘warm white’ or ‘cool white’. So, depending on your preference, check the packet to make sure have the right colour for you.
The light level in a room dictates what you can and can’t do, and it has a huge effect on how you feel. You can’t read very easily by a single candle, for example, and a romantic dinner for two isn’t so romantic under a 1,500-watt halogen lamp. The problem is, people need to use some rooms for multiple purposes, and these different functions call for varying amounts of light. Dimmers can be used to control light output from resistive incandescent, halogen, and (more recently) compact fluorescent lights and LEDs. There are a lot of other dimmer switch varieties out there, including touchpad dimmers and photoelectric dimmers, which monitor the total light level in a room and adjust the dimmer accordingly.
Precision Power can install dimming mechanisms throughout your home, in many types and effects. More specialized equipment can also be installed to dim fluorescent, mercury vapor, solid state and other arc lighting.
If your existing lights have a cheap dimmer switch, you may notice a strange buzzing noise. In addition to producing a soft buzzing sound, the abruptly shifting magnetic field will generate weak radio signals that can cause interference on nearby TVs or radios! Better dimmer switches have extra components to squelch the buzzing effect and can also be organised through PPE for change-over.
