In the market, LED downlights come in various shapes and vary in quality and performance. Whether for home or commercial lighting, What factors should be considered to purchase the right ceiling led downlight?
Downlight is a hidden luminaire embedded in the ceiling, which does not occupy indoor space and can achieve the overall unity and perfection of architectural decoration during installation. All its light is projected downward, which is a direct light distribution. The lamps are all CFL/incandescent bulbs with E27 and G24 bases. The LED downlight is an improved product developed on the basis of the traditional downlight. It uses a new type of LED lamp bead as the light source while eliminating the rectifier inside the downlight housing. Its design is more beautiful, lightweight, and similar, with only embedded Style, and surface-mounted style.
Based on industry experience, approximately 80% of quality issues with LED lights are attributed to the LED driver, so the quality of LED driver determined the quality of LED downlights, we can say. Therefore, whether what types of led downlights you choose, it’s crucial to choose the downlighter with top quality driver. High-quality LED drivers generally have a lifespan of over 5 years. Some well-known LED downlight driver brands in the market include Philips, Osram, Meanwell, DONE, LiFud, Eagleries, Greenso, Boke, and more. Additionally, selecting flicker-free drivers contributes to creating a more comfortable lighting environment.
Different color temperatures of lamps often give people different psychological feelings and visual effects.
LED downlights generally include three color temperatures:2800-3000K warm white; 4000-4500K natural white; 6000-6500K cool white. The lower the color temperature, the warmer the light, and the higher the color temperature, the colder the light. Low and medium color temperatures make people feel relaxed and warm, while high color temperatures make people concentrate and feel deserted. Therefore, for residential downlights, most of them is with 3000-4500K color temperature. For commercial downlight lamps, you need to choose a suitable color temperature according to different places of use. For how to choose the appropriate color temperature of the lamp, you can refer to this article.
The common power of LED downlights generally includes 5W, 7W 9W 10W, 12W 15W 18W 20W 24W 30W 50W. These powers can almost meet all application scenarios. The lumens (brightness) corresponding to different powers are different. In choosing the appropriate power (brightness) of any LED can give people a comfortable feeling. The light efficiency of the downlights on the market is basically 85-90lm/W. It can not only meet the basic lighting needs, but also give people a comfortable living environment .The 7W-9W (about 600-800lm) downlight is working for some places where is about 3meter height, such as living room, kitchen, bathroom, bedroom, etc. For some large indoor space,like supermarkets, shopping malls, or railway stations, generally 24W 30W 50W is more appropriate.
CRI refers to the ability to express the original color of the illuminated object. The larger the value, the higher the display index and the better the true color of the object can be restored. Generally speaking, the higher the CRI, the more expensive the product. Therefore, for different places, when choosing LED downlights, you can choose the appropriate display indicators; of course, for customers or engineering projects that can afford the cost, it is best to choose CRI90 downlight fitting.
LED downlights have many additional functions to choose from, such as dimming downlights, emergency downlights, CCT Changing led downlights and so on. These downlights with additional functions can often better meet customer needs. In large shopping malls, by using the DALI dimmable downlights system, the power and brightness output of all downlights in the entire mall can be adjusted at the same time, which can achieve more energy-saving effects than non-dimmable LED downlights. For the entrances and exits of some large buildings, the use of emergency downlights is a more reasonable choice, which is conducive to the lighting needs during power outages.
There are many different designs for the appearance and structure of downlights. Ordinary, cheap downlights generally have a simpler design, and the diffuser of the light-emitting surface is mostly flush with the outer ring of the downlight, and the anti-glare effect is not good. The structure design of the anti-glare downlight is more sophisticated. The light-emitting surface and the light source are hidden deep inside the lamp body, UGR<19, which is not easy to produce glare, which is beneficial to protect people’s eyesight and create a more comfortable environment. Of course, the price of anti-glare downlights is generally higher than that of ordinary downlights.
Compared with traditional downlight benchmarks, LED downlights have irreplaceable advantages
Before choosing the right LED downlight, you need to know your specific needs, such as whether you need to choose embedded installation or surface installation, household or commercial. Then determine the required downlight power and related functions. Finally, according to the project budget, choose the right downlight that meets your requirements.
