All About LED Lights

How to distinguish the quality of light bulbs? We can judge from the following four aspects. Primarily, the appearance of the bulb, mainly including design, packaging, parameters, etc. Next, the quality of light, whether the light is uniform, and whether it flickers. Further, reliability mainly refers to drive reliability and temperature management.Moreover, applicability is also an important aspect, because good LED bulbs will take into account the certification standards of different countries and regions, the characteristics of the power grid, temperature and humidity and other factors.

PAR and BR LED bulbs have certain similarities since they're both popular in recessed lighting. PAR and BR LED bulbs are also green solutions to outdoor and indoor lighting. However, they have some key differences too. BR LED bulbs emit a wide range of light, so they are considered floodlights. By contrast, PAR LED bulbs produce a much narrower beam of light, making them spotlights.

When you are shopping for adjustable LED lamps online, you may come across two different types: dimmable lamps and tunable lamps. What’s the difference between them?

A dimmable LED lamp can be dimmed by a dimmer controller, making a space brighter or darker. Tunable LED lamps (also called tunable white LED lights) allow users to control the color temperatures. 

Relamping literally means “replacing the bulbs in lighting fixtures.” But it represents a more innovative, energy-friendly, and cost-saving way of replacing or upgrading your lighting system, including replacing outdated lamps such as halogen, incandescent, or fluorescent lamps with LED lamps as well as properly dumping old bulbs. When you decide to relamp, you should consider  cost, maintenance, light quality, efficiency, etc. When it comes to residential lighting, you should also give special emphasis to eye comfort and lighting experience.

High bay lights are used to illuminate spaces with high ceilings. That usually means ceilings ranging from 20 feet to approximately 45 feet in height from the floor. YUJILEDS currently has two types of UFO high bay lights available on sale, namely 150W High Bay UFO LED Light and 200W Motion Sensor High Bay UFO LED Light.They are designed for both industrial and commercial applications and provide ultra-high color quality of CRI 95+ and extensive brightness.

Most of photography application wants lighting with high CRI & luminous efficacy(lm/W), but these two cannot be achieved altogether. In fact, it can be easily found from the LED market that they announce their LED has 140 lm/W or even 160 lm/W with CRI 70 or 80, but there can be rarely found LED has 140/W with CRI 95. Yuji now launches BC-2835DL with 140lm/W & CRI 97, 40% efficacy increased.

As widely recognized by the photographic industry, the accuracy of chroma is the top critical factor that affects the lighting quality, even more important than color rendition.YujiCapture™ optimizes a special selection of color tolerance of 50% more consistent compared to standard LED. Centering on the blackbody locus, YujiCapture™ presents a most ideal white light at different correlated color temperatures to eliminate the color deviation essentially.

LED lights are increasingly used in daily life, home, office, indoor and outdoor. As we transition over into an LED accustomed society, there is an issue that presents itself that not only has a negative effect on your health but as well your electronics. What exactly is flicker in LED lights and why are my LED lights flickering?

When you buy a lamp, you might wonder how much light it provides. It sometimes is indicated in Lumen which you can see on the outer packaging marked by the manufacturer. And sometimes it is indicated in Lux which interior designers mention when they explain how they design the house lighting. So, what are Lumen and Lux, and what’s the difference between them?
