Energy efficient lighting is a critical element of every business. Based on the kind of business you operate, lighting can account for 20 to 50 per cent of your total energy consumption. Ideally, with energy efficiency upgrades and continuous improvement of equipment, significant electricity cost savings can be achieved; giving you the highest return on investment.

Lighting design incorporates a well synchronized variety of fixtures: lighting, fixture placement and room finishes (like highly reflectivity paint) to produce improved lighting quality. To achieve the best efficiency and quality from any newly installed lighting system, consult RJ Consulting, the lighting professional with profound experience in energy efficiency.
When it comes to lighting technology, be sure to choose an energy efficient lighting technology. Below are highlights of various lighting technologies and their efficiency.
Incandescent Lighting Technology
The simple yet inefficient innovation has dominated lighting applications to date. Incandescent lamps are commonly found in:
- Wall sconces
- Recessed “can” fixtures
- Exterior lighting
- Suspended fixtures
- Accent and “track” lighting
- Lamps and task lighting
- Illuminated exit signs
Compact Fluorescent Lamps (CFLs)
Technically, CFLs are fluorescent designed in a compact form to replace the incandescent lamps in conventional screw-in fixtures. These lamps are energy-efficient and come in a variety of sizes and styles, making them ideal for various applications.
CFLs have been qualified by ENERGY STAR as lamps that use 75% less energy than a normal incandescent bulb, and can last up to 10 times longer. Compared to a 100-watt incandescent bulb, a 32-watt CFL can save you about $30 in electricity costs over its life.
Given their durability, CFLs are ideal for hidden places because of their reduced need for frequent replacement. In addition, CFLs are easy to handle, making them safer than halogen and incandescent lamps.
Improved Halogen Systems
More often, halogen lamps are used to replace incandescent lamps so as to enhance efficiency and general service life. Most ordinary halogens can also be replaced with the high performing “Infrared” (IR) halogen lamps. These work by raising the operating temperature of the halogen lamps, hence increasing efficiency. Though halogen lamps are more efficient than incandescent lamps, these lamps are inferior in efficiency compared to the High Intensity Discharge (HID) and fluorescent lighting systems.
Fluorescent lighting is considered the “standard” lighting technology for spaces like offices and classrooms since it is approximately four times more efficient than incandescent lamps. However, fluorescent lighting systems that are old and obsolete can lead to poor flicker and light quality. Innovations in the world of fluorescent lighting systems have led to development of new systems that offer improved lighting quality, energy efficiency and design flexibility.
A standard fluorescent lighting system consists of primary elements that include ballast which basically alters incoming voltage and controls the electrical current, and the lamp (usually bulb or tube) which is the source of the artificial light.
High-Intensity Discharge (HID) Lighting Systems
With their high intensity, HID lighting systems range from 50 to 2,000 watts and are effective for lighting wider area from a high ceiling. Just like the other fluorescent lamps, HID lighting systems contain ballasts.
Note: Any system made before 1978 may have potentially harmful substances like Polychlorinated biphenyls (PCBs).
These are some of the HID technologies that are most efficient for your facility. Turn to RJ Consulting, your lighting professional for more about specific energy efficient T5 lighting systems that can be used instead of the HID lighting systems.
Exit signs are an effective, low-labor and low-cost chance to increase the safety and energy efficiency of your facility. Installing ENERGY STAR qualified exit signs can increase your energy efficiency by up to 3 to 8 times.
Fixtures (Apparatus that contain the lamp)
Using a specific energy efficient lighting technology such as T5 or T8 electronic ballasts and fluorescent lamps is an important step towards enhancing your facility’s energy efficiency in a bid to save money.
Notably, lighting is also a system and highly relies on the quality of the fixture, in combination with the ballast, lamp, and placement (position of fixtures in any room, which impact on the amount of usable light supplied), to perform efficiently.
For the best light quality and energy efficiency, contact RJ Consulting, your lighting expert and designer to help you make the right decision when selecting fixtures.
Controls are a critical part of a lighting system. They maximize your system’s flexibility while automatically eliminating light consumption. The most common controls include:
- Occupancy Sensors
- Bi-level Switching
- Photocells (Daylight Sensor)
