Track Lighting Fixture Tips

May 13, 2011 Category :Lighting Wiki 0

Track Heads are best for spot lighting. Par bulbs and MR16 low-voltage halogen bulbs come in a variety of beam spreads to focus the light as narrow or as wide as you’d like it. For general illumination, use wide angle bulbs, and for spot lighting of specific items, use a narrow angle or spot. There are many Track Head Accessories that can add style or beam control to your light. You can also add a lens to most fixtures to direct the light or add color. Outdoor lighting 2011 is a new trend of decoration.

Pendants are typically made up of 3 components: the connector to the track; the Socket Set which includes the stem, socket and bulb; and the Shade which is attached to the socket set. Pendants can also be adapted to a single pendant or cluster of pendants by connecting the Socket Set directly into a Ceiling Canopy. In this case no track connector is required.

Fluorescent wall washers are typically used to Illuminate an entire wall. They are perfect for murals or large pictures where light is needed to spread out. Since these are larger fixtures, a higher ceiling might be required so the fixtures do not block the artwork. If Fluorescent wall washers are placed too close to the wall, the baffles (that help direct the light) will show as black lines on the wall/painting.

Note for Low Voltage systems: A transformer with a wattage rating equal to or greater than the total watts used on the system is required. Example: Five 50-watt pendants in a system will require no less than a 250-watt transformer. Low voltage track fixtures can be placed on line voltage track by using a track connector with a transformer installed to drop to voltage of that fixture. The transformer is designed to blend in with the track so it is not as noticeable. Each system has its own advantages and disadvantages. This Track Lighting Guide will aid you in design considerations for each track system we offer.

Some Tips of Lighting Maintenance

April 21, 2011 Category :Lighting Wiki 0

Proper lighting system maintenance is essential to high quality, efficient lighting. Systematic lighting management methods and services from lighting specialists can help organize the process and assure continued high performance of any lighting system.

Lighting maintenance is more than simply replacing lamps and ballasts when they fail. Facility managers today must manage their lighting resources (i.e., fixtures, lamp/ballast inventory, labor, energy) to sustain the quality of a lighting system.

The light output of a luminary decreases with age and use, yet the energy input remains unchanged. Because the human eye is extremely adaptive to gradually changing lighting conditions, most occupants do not notice the gradual decline in light levels. Eventually, however, the reduction will affect the appearance of the space and the productivity and safety of the occupants.

In the past, lighting designers have dealt with this problem by increasing the number of fixtures or lamps to compensate for the future light loss. While this simplifies maintenance, it is not an acceptable solution due to the added initial equipment cost, energy cost, and energy-related pollution.

Three factors cause light loss—— lamp and ballast failure, lamp lumen depreciation, and  luminary dirt depreciation. Light loss gradually decreases system efficiency over time. In combination, these factors commonly reduce light output by 20-60%. No corresponding energy reduction is associated with light loss, except with lamp and ballast failure.

When lamps and ballasts fail, they no longer provide light for the space. Often, failed lamps and ballasts remain in fixtures for months. Lamp manufacturers list the “average rated life” for their products. The average rated life is the number of operating hours after which one-half of the lamps can be expected to have failed. A few lamps may fail soon after installation, and the rate of failure will increase as the time in use increases.
