Common Problems  - and what to look for:
A.   Lamp does not light -
B.   Lamp cycles on and off -
C.   Lamp is too bright, too dim or changing colors -
D.   Lighting Fixture Problems -

A. Lamp does not light
Does the fixture have a Photo Cell?
Cover the photo cell completely with black tape.  Replace the lamp with a known working lamp of the correct wattage and type.   If the new lamp still does not light, check the voltage at the lamp socket.

No voltage at the lamp socket?
Bypass the photo cell and try again.
B. Lamp cycles on and off  
Repeat the same steps as mentioned above -
Under normal circumstances the lamp needs replacement.
C. Lamp is too bright, too dim or changing colors
If the lamp is new, give it some burn-in time before considering it defective (3-4 hours). If the lamp is old, under normal circumstances the lamp needs replacement. If a known working lamp is still abnormal, the ballast needs replacement.

D.  Lighting Fixture Problems

  • Water / moisture entering the fixture. Look for signs of rust, corrosion, stains on the glass, etc.
  • Bugs! Exterior fixtures fill up with dead bugs. This clouds-up the glass and lamps.
  • Other sources of light entering a photo cell.  This will cycle the fixture on and off.
  • Most HID fixtures have multiple voltage taps. Check incoming voltage and connection tap.
  • Lamp sockets may be broken and may have burnt connections.
  • Wrong lamps installed.  This is common because of the similarity of HID lamps.
  • Pinched wires behind the shield or cover. Many times this will be a delayed problem
More Information about HID Lamps
How HID Technology Works
HID Lamps or “high intensity discharge” lighting is in some ways similar to fluorescent: an arc is established between two electrodes in a gas-filled tube which causes a metallic vapor to produce radiant energy. In this case, however, a combination of factors shifts the wavelength of much of this energy to within the visible range, so light is produced without any phosphors. In addition, the electrodes are only a few inches apart (at opposite ends of a sealed “arc tube”) and the gases in the tube are highly pressurized. This allows the arc to generate extremely high temperatures, causing metallic elements within the gas atmosphere to vaporize and release large amounts of visible radiant energy. There are three main types of HID lamps: mercury vapor, metal halide and sodium. The names refer to the elements that are added to the gases in the arc stream which cause each type to have somewhat different color characteristics and overall lamp efficiency. Ballasts and Warm-Up Time
HID Lamps have special electrical requirements that must be supplied by a ballast. With HID sources, however, the ballast must be specifically designed for the lamp type and wattage being used. In addition, HID lamps require a warm-up period to achieve full light output. Even a momentary loss of power can cause the system to re-strike and have to warm up again—a process that can take several minutes. In applications where constant illumination is important for safety and security, a backup system is often required. The LUMALUX® Standby lamp offers instant re-strike capabilities once power is restored, making it an ideal choice for applications where safety is a concern. Metal Halide Lamps
Metal halide lamps are among the most energy efficient sources of white light available today. These lamps feature special chemical compounds known as “halides” that produce light in most regions of the spectrum. They offer high efficacy, excellent color rendition, long service life and good lumen maintenance. Because of their numerous advantages, metal halide lamps are used extensively in outdoor applications and in commercial interiors. Recently, a wide range of low wattage METALARC® lamps has been developed, offering high performance in a more compact size and bringing HID benefits to applications such as retail and display lighting. There is also an entire family of metal halide lamps called METALARC® Ceramic that employs ceramic arc tube technology to improve color rendition and consistency. METALARC PRO-TECH® lamps represent an additional innovation, featuring a special shroud that surrounds the arc tube, enabling use in open fixtures. High Pressure Sodium Lamps
High-pressure sodium lamps were developed primarily for their energy efficiency. Mercury and sodium vapors in the ceramic arc tube produce a yellow/orange light with extremely high LPW performance and exceptionally long service life (up to 40,000 hours). High-pressure sodium lamps render colors poorly, which tends to limit their use to outdoor and industrial applications where high efficacy and long life are priorities. Variations within the LUMALUX family of lamps include a Standby version with 2 arc tubes for rapid re-strike after power interruption. LUMALUX PLUS® ECO® eliminates cycling at end-of-life. Low pressure sodium sources are also available. Since these lamps produce light at only one wavelength in the yellow region of the spectrum, they are used where energy efficiency and long life are the only requirements. Mercury Vapor Lamps
Mercury vapor lighting is the oldest HID technology. The mercury arc produces a bluish light that renders colors poorly. Therefore, most mercury vapor lamps have a phosphor coating that alters the color temperature and improves color rendering to some extent. Other HID types that offer higher LPW and better color properties have largely super ceded the use of this lamp.
