So, what is the best LED light colour for studying? In short, the answer is natural white LED light because it mimics the natural daylight as closely as possible.
Soft white (2,700 to 3,000 Kelvin) is warm and yellow, the typical color range you get from incandescent bulbs. This light gives a warm and cozy feeling and is often best for living rooms, dens and bedrooms.
Fundamentally, there are three different types of LED technology that are used in LED lighting – DIP, SMD and COB.
The average lifespan of an LED is often rated up to 50,000 hours. This is about 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen and 8-10 times longer than a typical CFL. If used 12 hours a day, an LED rated at 50,000 hours will last more than 11 years.
Use warmer colored light bulbs marked 2700-3000K for your bedroom lamp, or consider dimming your lights as you wind down for the evening. Need an energy boost? Use a cooler, bluer light bulb marked 5000K because they give off a natural light, increasing your energy levels and alertness.
The best light bulb for a bedroom is an LED one. Although LED bulbs are more expensive than incandescent or halogen bulbs, they last longer than their counterparts and produce a warm, soft light. This type of bulb produces more blue light than other types of light bulbs.
The higher the wattage, the brighter the light, but also the more power it uses. The efficiency of this system was introduced using incandescent lamps. For instance: 40 Watt incandescent lamp produces only 380-460 lumens and uses 40 Watts of energy per hour.
Led Lights Use Helps
The high efficiency and directional nature of LEDs makes them ideal for many industrial uses. LEDs are increasingly common in street lights, parking garage lighting, walkway and other outdoor area lighting, refrigerated case lighting, modular lighting, and task lighting.
Just like other light sources, LED light bars can get very hot after a certain period of time. As such, make sure that you avoid touching the housing of your LED light when it is switched on. Otherwise, you might burn yourself.
Common Problems with LED Lighting
LED Light Flickering.
LED Buzzing or Humming Noise.
Too Bright light.
LED Light Too Dim.
LED Light Stopped Working.
LED Flashes on and then Goes off.
LED Dimming Does not work.
LED Strip Showing the Wrong Color.
The average lifespan of an LED is often rated up to 50,000 hours. This is about 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen and 8-10 times longer than a typical CFL. If used 12 hours a day, an LED rated at 50,000 hours will last more than 11 years.
Unlike traditional bulbs, LEDs only emit light in a 180 degree in front of them. This means that there is no wasted light, which ultimately means less wasted energy and more savings.
The material used most often in LEDs is gallium arsenide, though there are many variations on this basic compound, such as aluminum gallium arsenide or aluminum gallium indium phosphide.
LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light.
LEDs work on the principle of Electroluminescence. On passing a current through the diode, minority charge carriers and majority charge carriers recombine at the junction. On recombination, energy is released in the form of photons.
LED Lights do not use harmful chemicals
Unlike the compact fluorescent lights which have 4 to 5 milligrams of mercury present in each of them, LED lights are free of any chemical which can be hazardous for the environment or public health.
between 1.8 and 3.3 volts
Typically, the forward voltage of an LED is between 1.8 and 3.3 volts. It varies by the color of the LED. A red LED typically drops around 1.7 to 2.0 volts, but since both voltage drop and light frequency increase with band gap, a blue LED may drop around 3 to 3.3 volts.
Yes, new technology LED lighting can and will get hot, but when compared to the lighting of the past, temperatures are much safer. The heat from the lighting will also warm your surrounding environment but in comparison to old incandescent lighting, this ambient heat is greatly reduced when using LED lighting.
plastic
LED bulbs are made of hard durable plastic, making them almost indestructible. Something to keep in mind is how much you can save on your power bill. LED bulbs use 90% LESS electricity vs your traditional glass incandescent bulb.
