Lighting is typically categorized in ambient, task, accent and decorative lighting. Choosing the right light for different light functions and areas in your home However, for some areas, better color rendering of 90 or above can be desirable, we explain that in the next section. A 2700K incandescent light bulb has a CRI of 100.Ī value of above 80 is with current LED technology considered a good CRI and will be sufficient for most applications. The color rendering is expressed as the Color Rendering Index or short CRI. And by correctly we mean compared to a natural light source like the sun or an incandescent bulb. Light sources differ in their ability to display the colors of objects “correctly”. Have you ever been to a store and thought that you are color blind, because you couldn’t quite make out if the piece of clothing you were looking at was a dark green or blue? If so, then you experienced poor color rendering by the light fixture inside that store. The issue here is that they chose a high kelvin, cool color temperature instead of a warmer color temperature. People often complain about the cool, sterile light appearance of CFL bulbs compared to incandescent bulbs. The sun at noon on a clear day produces a light of approximately 5500K.

A typical incandescent bulb has a color temperature between 2700K and 3000K. The lower the number, the warmer the light will be and the higher the number the more cool and blue the light will appear. When we want to know if a lighting fixture or bulb creates a warmer or crisper, cooler light we need to look for the kelvin number. The color appearance or correlated color temperature (CCT) of light is measured in kelvin (K). Lumen is the unit of measure for brightness and tells us how much light a particular lighting product emits.įor reference, a typical incandescent 60 W bulb emits approximately 800 lumens. So the only factor to pay attention to when looking for brightness of an LED light is Lumens. While for incandescent bulbs wattage and brightness had a direct correlation, this is not true for LED products and since LED’s consume much less power (Watts), it’s impossible to compare brightness of an incandescent and an LED bulb based on wattage. When using LED’s it is important to understand three conceptsĪfter all, LED products are still more expensive than comparable incandescent products and they will be a much longer lasting appliance, so we want to make sure we are buying the right product for the job.įirst off, we have to let go of the misconception that wattage equals brightness.

Soft white resembles the warm tone of an incandescent bulb whereas bright and daylight being more crisp and cooler with a blueish appearance. With CFL’s came the option of choosing the light appearance described mostly as soft white, bright white and daylight. When buying traditional incandescent light bulbs, all we needed to pay attention to was the bulb shape, wattage which indicated the brightness of the bulb and the screw base size to make sure it fits into the lamp. Due to their compact shape, LED lighting solutions come in all forms, shapes and sizes, providing an almost unlimited amount of ways light can be used and added to a home environment. In addition, LED’s don’t only come in a traditional light bulb shape. LED products are a very good solution to meet or exceed the stringent energy consumption requirements outlined in this standard. When living in California, every new construction or renovation project is subject to the 2013 California Energy Efficiency Standard, also known as Title 24.

This article explains the “must-know” terms that homeowners or contractors should be aware of when buying LED products, provides guidance on how to choose products for different areas in a residential environment and points out some of the pitfalls to avoid and be aware of to make the switch to LED lighting a success.īesides being much more energy efficient than incandescent and CFL options, thus able to provide significant energy savings, they last much longer, don’t contain Mercury like CFL’s and provide a lot more options for brightness and light appearance (warm vs. While some LED products might just look like any other light bulb or fluorescent tube, the variety of products, new terminology introduced by the lighting industry and the fact that LED’s are a different technology from what we have been used to for decades can make the switch to LED lighting quite challenging. There are more LED products and alternatives available on the market already than there ever have been for traditional incandescent and compact fluorescent (CFL), energy efficient bulbs.
