LEDs have the potential to change the way we light our homes and offices and generate savings in energy costs for those who install them.
Residential Recessed Downlights
Recessed downlights are the most commonly installed lighting fixture in new residential construction, with lighting accounting for 15-20% of a households electricity usage. Both compact fluorescent and LED lighting fixtures can decrease downlight wattage by 75% or more through increased efficiency and dimmable fixtures, which is unavailable in compact fluorescent systems. Learn more about how LEDs can be used in a downlighting setting.
Portable Desk/Task and Kitchen Undercabinet Lighting
The small size and high directionality of LEDs make them ideal for lighting work or task specific areas. Although their is significant promise for these applications, the recent nature of the product development makes it important to evaluate specific products before purchasing. These include, a luminaire designed to move heat away from the back of the LED, takes advantage of the directional nature of LED light, uniform colour distribution, glare shielding, and others. More information on LEDs in desk and task lighting can be found here while specific information on kitchen lighting is also available.

Many local hydro providers offer various rebate programs for upgrading to new energy efficient technologies.
NRC Office Environment Studies
This project is designed to spur penetration of SSL in office buildings to realize their energy-saving potential. This project will consist of four tasks, which may undergo several iterations:
- Facilitate workshops to stimulate new visions of office lighting.
- Together with partner manufacturers, fabricate full-scale working prototypes.
- Evaluate these prototypes in NRC-IRC’s Indoor Environment Research Facility for both physical performance and the mood, comfort, satisfaction and task performance of participants.
- Demonstrate successful prototypes in an open forum.
This research looks at systems that provide individual dimming control of lighting to office workers, particularly in an open-plan office context. We address such questions as: How do people use these controls? Are their choices energy-efficient? Can we develop new control options for greater efficiency? Can we integrate these lighting controls with individual control of ventilation, and how does such a combined system perform? Does having this kind of control improve occupant satisfaction, mood, and task performance?
