How to Convert a Torch to Light an LED

an image which shows a comparison between the LED bulb (left) and the standard incandescent bulb (right).
The torch is excellent. They are well manufactured and durable, stylish and functional. However, they are limited by the batteries your use, and the lifetime of the bulbs. If only it was possible to change the standard incandescent tungsten [...]

LED Display Color Depth

“Dimming” and “shading” refer to entirely different functions and the terms should not be interchanged. The word “dimming” refers to a uniform brightness adjustment across the entire display to correct the intensity for ease of reading different ambient light conditions. “Shading” or color depth, affects the light output variations of each individual red, green and [...]

LED Display Best Video

Video can be described as display a moving image, which is made up of many individual frames played at a fast rate. Good video is played at 30 frames per second or higher. Slower rate can begin to look choppy and affect the presentation quality.
Video content can be “live”, such as previously recorded live feeds, [...]

What Problems shall be Considered for the Design and Installation of Outdoor’s Screens?

Major problems for outdoors screen are shown as below:
1. The display screens installed outdoors will experience the weathering and dusts in abominable conditions. The electric device drenched or seriously moistened may stuck in short circuit or even fire, which result in failure or even fire and losses;
2. The display screen may suffer from lightning strike [...]

Why Are LED Lights Better?

There is no doubt about it, LEDs are better LED grow lights are significantly better than traditional HID lights. If you are still uncertain, all four of these categories offer compelling reasons why you should switch to LED growing today!
Less Heat, Energy, and Pollution
Reducing heat and energy is one of the biggest places where LED [...]

Why Don’t You List the LUX or Lumens on Your Lights?

We could, but it would be a meaningless measurement.
Lumens are a measurement of how much light energy a light source emits. The problem is that this measurement is based around the wavelengths of the human eye, and NOT the PAR wavelengths. Using Lumens is great for measuring light used in flashlights or office buildings, but [...]

So Why LEDs?

LEDs (Light Emitting Diodes) emit only certain wavelengths of light and have a fantastic lifespan (around 50,000 hours), making them the perfect solution to efficient plant growth. The reason why LED growing is not commonplace is because it has been difficult to find LED lights powerful enough to to sustain good growth. Technology has rapidly [...]

What Is PAR Light?

It may come as a surprise to learn that plants don’t actually “see” the same light we do. The photosynthesis reaction that makes plants grow reacts to only certain light wavelengths (colours). This is exactly what PAR light is (Photosynthetically Active Radiation). This means that if you buy a traditional white light, you will be [...]
