Lighting FAQ’s

1. Lamp

Synonymous with light bulb. The three broad categories of electric lamps are incandescent, fluorescent and high-intensity discharge.

2. Halogen Lamps

High pressure tungsten filament lamps containing halogen gases.The halogen gases allow the filaments to operate at higher efficacies than incandescent lamps.Halogen lamps also provide brighter, whiter light with better color characteristics, longer service life and improved energy efficiency.

3. Compact fluorescent lamps

Compact fluorescent lamps allow fluorescent lighting to be used in many additional applications.The reason for this is the small diameter tubes that are used can be bent into one single base.

4. Fluorescent lamps

A low mercury pressure vapor discharge light source.The electric discharge generates ultra-violet energy; this is absorbed by a phosphor and converted to visible light.

5. High-Intensity Discharge Lamps (HID lamps)

Lamps in which an arc passing between tow electrodes in a pressurized tube causes various metallic additives to vaporize and release large amount of light.All HID lamps offer outstanding energy efficiency and service life.Metal halide lamps also offer good to excellent color rendering index.

6. Incandescent Lamp

Lamps in which an electric current passes through a filament wire, the heated wire glows.Filaments of standard incandescent lamps are enclosed in a vacuum or gas-filled bulb.Incandescent lamps provide low initial cost, good color rendition and excellent optical control.

7. Par lamps

Pressed aluminized reflector lamp, with the outer bulb formed from two pressed glass parts that are fused or sealed together, PAR lamps may be incandescent, halogen or HID types.

8. Photo-Optic Specialty Lamps

Photo-Optic specialty lamps use a variety of technologies to meet the precise levels of performance required by the entertainment industry, science, medical and other high-tech fields.

9. Ballasts Basics

Ballasts have two primary functions:

  1. start the lamps
  2. control operation of the lamp once it has started.

10. Ballasts Types

There are three types of lighting ballasts:

  1. Magnetic: an inefficient device that uses a core and coil assembly transformer to perform the minimum functions required to start and operate the lamp
  2. Hybrid or “low frequency electronic” a magnetic ballast with a few electronic components that switch off voltage to the lamp coil once the lamp has started.Minimal increase in efficiency is achieved via a more expensive magnetic core material and the absence of power to the lamp coils during operation.
  3. High frequency electronic: operates lamps at frequencies above 20,000Hz.Maximum efficiency is obtained through the use of electronic circuitry and optimum lamp operating characteristics.

11. What is a color rendering index (CRI)

The color rendering index measures the effect light has on the apparent color of an object/surface.Light that has a higher CRI will make nearly all colors look natural and vibrant.The lower the CRI the more washed out color will look sometimes even completely changing the hue.

12. What is color temperature (ct)

Measured in kelvin, color temperature indicates if a color has a warm, midrange or cool appearance.Lower color temperatures 2000-3000 kelvin offer a warm light in the red, orange, yellow range. Higher temperatures 5000k and above offer a cooler light in the bluer ranges.
