Featured by its versatile, flexible, energy-efficient and easy installation, LED track lighting is becoming the most popular lumininares for commercial and residential lighting projects.
Track lights are characterized by having a length of track that holds LED spot lights. This is a highly versatile form of lighting that can be cut, curved and adjusted to meet your lighting requirements. Then coming to the main issue, how to choose the right LED track light? Before choosing, you need to consider below issues:
1. Type of Track System
Track systems are available in different lengths and types, including low voltage and line voltage, single phase and three phase. To create a layout of track system, it will consists of tracks in specified lengths and connectors, like linear joints, L/T/X connectors, and flexible connectors. The track system can be directly installed to the ceiling (recessed or surface mounted) or suspended from the ceiling.
Here below are the most popular types of track systems:
– One Phase Track System
Under this straightforward track system, all the lights are on the same circuit. When you turn on/off the lights, all the lights in the system will turn on/off together.
– Three Phase Track System
Three phase track system is set with three circuit on one track, controlled by three switches separately. This means the lights in different circuit will be controlled by the corresponding switches for a more professional display.
– Dali Track System
Dali track system includes both normal input voltage and wires for transmitting the control signal to the lights.
2. Type of Lighting Fixtures
Once the track system is confirmed, you need to consider whether the track lighting fixtures are compatible with the track system or not. Choose the fixtures which can be compatible with the track system.
The heads of track lighting are normally used for general illumination, spot lighting, wall washing and applications where you need directional light. Then consider the space or object that you want to be illuminated, and pay attention to the important specification of track lights, like beam angle, CCT, and CRI.
– Beam Angle In order to illuminate the object area with bright and evenly-distributed light, you need to choose the right beam angle. So it is important to know the beam angle of the track lights used, the distance between track lights and object, as well as how large the object area.
– Correlated Color Temperature (CCT)
The correlated color temperature (CCT) is a measure the color appurtenance of the lights in Kelvin (K) degree. Typically, CCT for commercial and residential lighting applications ranges from 2000K to 6500K. Light colors can affect our daily mood, as colder colors help to improved wakefulness and productivity, while warmer colors increase relaxation. For retail lighting, retailers usually use cooler colors for cold-tone products, while use warmer colors for warm-tone products.
– Colour Rendering Index (CRI)
The Colour Rendering Index (CRI or also denoted as Ra) is a measure of light’s ability to properly render colour (ranges from 0 to 100 – the highest possible score). Colour rendering is particularly important for commercial applications in order to reveal true and vivid colours of the products, artworks or architectural elements that are of interest.
The following table shows the quality of Colour Rendering Index:
Ra = 90 – 100 Excellent Ra = 80-90 Good Ra = 60 – 80 Moderate Ra < 60 Poor
To choose the right LED track light, you should consider not only above necessary factors, but also others, such as accessories, lighting efficacy, and etc.
