Whether we want to use LED light bulb in our house or in a project, we generally have a complexity like how many watts and lumens that we need. The first question that comes to our mind when buying a LED light bulb is that; Is it enough to light...
Since the concept of LED lighting has entered our lives, we have started to learn very different terms. One of them is the "full spectrum". Some manufacturers state that their LED lighting products emit full spectrum light. So, what is full spectrum?
Light bulbs are generally rated in two different classes, warm white and cool white. Generally, warm white indicates 2700-3000K color temperature range, while cool white represents 6000K-6500K color temperature. Which one should we choose for our houses?
Although common grow lights emit blue and red light, these lamps come in many different color combinations. Because each color has different effects on the plant. So, what color light is useful in plant growth?
Vantablack is a super black coating developed in 2014 by Surrey NanoSystems, a British company. The materials to which this coating is applied absorb 99.965 percent of light. This makes it the blackest known man-made coating.
Power and energy are two main terms used in electrical and electronic systems. Many people think that energy and power are the same concepts. These two terms are related but not the same. Energy is basically the ability to do work. Power is the amount of energy used per unit...
CFM stands for cubic feet per minute. CFM is a volumetric unit of flow. CFM represents the maximum amount of air that a fan can move at maximum speed and without any restrictions. CFM is related to the fan’s motor (rotational speed), blade length, blade pitch and shape.
The unused power caused by the inductive and capacitive effects of transmission lines or electrical loads using alternating current is called reactive power. Reactive power, also known as virtual power or phantom power, is measured by VAR (Volt-ampere reactive).
Photometry is the measurement of visible light as perceived by the human eye. Photometry is a name formed by combining the words photo and metry. Photo is a prefix meaning light. Metry refers to the process of measurement.
The majority of rechargeable AA and AAA batteries on the market are Nickel-metal hydride (NiMH) batteries. NiMH batteries can be charged/discharged for up to 500-1,000 cycles. This means they can be used for up to 10 years at an average charging frequency.
Electrical devices can consume energy even when we are not using them, causing our electricity bill to be high. So what are the effective ways that we can easily apply to reduce the electricity bill?
In the lighting industry, there are some signs that provide information about the reliability, efficiency and quality of the product. In lighting devices; UL, cUL and DLC are frequently encountered abbreviations. So, what do all these abbreviations mean?
In the past, perhaps few would have predicted that LEDs in watch displays would be the lighting technology of the future. But it has happened and LEDs are now being used for general lighting purposes. Could OLEDs or laser diodes replace LED technology? And what about light-emitting plants?
Blue light alone does not have a whitening effect. The purpose of the blue light is to speed up the teeth whitening process. It should be used with a bleaching solution. The combination of chemical and blue light significantly increases the final whiteness level of the teeth.
A solar charge controller is a type of regulator that transfers the energy from solar panels to the batteries and load. The charge controller is used to charge the batteries with the electrical energy obtained from solar energy. The charging voltage is regulated to suit the batteries and the batteries...
Light travels much faster than sound. One of the most classic examples is lightning. When lightning strikes, the first thing you see is a flash of lightning in the sky, while the sound of thunder is heard a few seconds later.
An oscillator is an electronic circuit or device that can convert a steady-state signal into an oscillating signal (sine wave signal). Oscillators are used to generate repetitive electronic signals. An oscillator can convert a steady-state DC signal into a periodic AC signal at a desired frequency.
When you heat something, you notice that its temperature rises. This may make you think that heat and temperature are the same thing. Because of this misconception, heat and temperature are often used interchangeably. Although the two concepts are related, they are not the same. It is therefore very important...
LED street lights are modern lighting devices used to illuminate roads, streets and alleys. LED luminaires have a different and more complex structure than traditional luminaires. Are you wondering what is included in an LED street light?
Calibration is a documented comparison of a measuring device to a traceable reference device. Calibration refers to the process that enables measuring instruments to produce outputs that provide high levels of accuracy and precision. The main purpose of calibration is to ensure the accuracy of measuring instruments and to minimize...
