The UGR ranges from 5 to 40, with a lower number being desirable because it represents less glare. To measure glare, we use the Unified Glare Rating (UGR), which is the luminance of the light source divided by the background luminance of the room. Glare is a measurable phenomenon, which is determined using a formula. Indirect or reflected glare normally results from a reflection off interior surfaces. Small, bright sources of light typically emit glare - both direct and indirect. Over excessive brightness, known as glare, can be visually uncomfortable. Visual comfort is crucial in office, classroom, hospital, and other applications. Compared to old fluorescent tubes, LED panel lights deliver more light while using less energy, meaning that they produce more lumens per watt and are more energy efficient.

Wattage can be calculated with lumens (lumens per watt) to measure the energy efficiency of a LED light fixture. Although it is still used in LED lighting products, it does not reflect the actual brightness of the light like it did for incandescent bulbs. Wattage measures how much energy is consumed by a light source. As a general guide, below is a table of brightness level recommended by AZ/NZS 1680.1:2006 (a commonly-used lighting standard) for different types of activities: Class of Task However, please note that when measuring the brightness of an area such as a working table, a checkout counter or a reading surface, footcandle or lux is used. Important Specs of LED Panel Lights Lumens and WattsĪn important spec to review, lumens are a measurement of the total amount of light emitted from a light source. LED panels are truly a dream-come-true lighting system based on their many attributes. The panels don’t stick out, are unobtrusive and you won’t even notice them unless they are turned on. They are a great choice for those going for a minimalist, contemporary style in their lighting arrangement. One of the most popular features of LED panels is their slim look and feel. Many LEDs on the market can easily last 30,000 hours, or over a decade under common use.

This means you won’t have to spend money on maintenance or replacement panels for years. In terms of energy efficiency, LED panels have a significant advantage over legacy lighting systems because they produce much more lumens per watt of energy used.Īnother advantage of LED panel lights is that they last a very long time. Further, the evenly diffused light produces less glare and is more pleasing to the eyes. The lighting in the room will appear smooth with no distracting dark spots or overly brightened sections. In contrast to downlights or spotlights, these installations produce light with large illumination panels so light is distributed and diffused in evenly spread manner. As a result, LED panel lights have become one of the most popular choices for creating stylish, interior lighting. Further, they don’t require an obstructive installation or much energy to turn on. These lights are a low-weight, elegant illumination solution for lighting. LED panel lights are constructed with low-weight aluminum frames and diffusers. A growing number of discerning buyers are turning toward LED panel lights to illuminate their homes and businesses.
