Low Bay Lighting Vs. High Bay Lighting

In warehouses, factories and manufacturing facilities, bay lighting is usually the lighting of choice when it comes to spaces with 10 ft. tall ceilings. But the exact height of the ceiling could be the difference between whether high bay lighting or low bay lighting are needed. Read on to learn the differences between the two and what would be the best choice for your space.

High Bay Lighting

In most instances, high bay lighting is used for ceilings that are 20’ and 40’+ tall. Usually, they will have lens angles for the LED bulbs, which then spreads the light. High bay light fixtures can come in several types of light sources - traditionally, they were found in metal halide or high pressure sodium technologies, most have upgraded to more efficient technologies such as LED lighting.

Low Bay Lighting

Ceilings that are between the heights of 12’ and 20’ will usually use low bay lighting. Lens angles are also used to further spread the lighting. By using these lens angles to direct the lighting in specific places, sometimes less low bay lights are needed.

One of the main differences between the two, besides height requirements, is that the bulb intensity and lumen output will vary. Obviously, the low bay lights will have a very high bulb intensity, as high bay lights have more room for the light to defuse before reaching the ground.

LED bay lighting is the most energy-efficient option on the market. Specifically designed for larger spaces, these improve visibility and worker safety. LED bay fixtures are instant on and don't lose life hours from constant on-off cycles like HID and fluorescent fixtures do. Therefore, they don't need to be replaced as often, which cuts maintenance and replacement costs.

iPhone X to make impact on LED industry

On Sept. 12, Apple excited audiences with the reveal of the new Apple Watch Series 3, 4K Apple TV, iPhone 8, iPhone 8 Plus, as well as the long-awaited iPhone X. It’s no surprise that Apple brings around the best of the best, setting the industry standard in every way when it comes to smartphones, and the iPhone X is no exception to this. In fact, this phone will be the first of Apple’s iPhones to use a full-screen OLED display.

Previously, Apple used an LCD display, but with their goal of an all-display smartphone, engineers switched to OLED materials. This switch will have a significant impact on the LED backlight business, because while the market of mobile LED backlight is shrinking, it will be eventually be replaced by OLED. By 2017 end, the percentage of OLED display adoption will increase from 22% to 27%.

Now with Apple’s intro of 3D sensing technology with the iPhone X, other companies will make the switch as well, in order to keep up with the industry leader. Research experts expects that the market for 3D sensing solutions used for mobile devices will also significantly grow in 2017, with the estimated market value to reach $1.5 billion this year, expecting to grow to $14 billion by 2020.

The iPhone X sports Quad-LED True Tone flash, and its light sources are CSP LEDs. As this new type of smartphones are becoming thinner, the area for the LED light sources will be smaller. Only a few LED manufactures can downsize their product without resulting in less-bright LED, which means there will be a growth in the value of the flash LED market to $811 million in 2017.
