Difference Between LED Downlight and LED Spotlight

1. LED downlight

LED downlight is classified as open installed one and built-in installed one. For open installed one, you can directly install it without opening hole or suspended ceiling. For built-in installed one, you need purchase as per reserved hole or open a hole as per purchased size, and then install it with opening hole and suspended ceiling, normally, it has 2inch, 2.5 inch and 3 inch, the larger the size, the higher the body of light is. If you have high requirement for the depth of suspended ceiling, install the ceiling height above 13 cm for LED downlight (if the suspended ceiling is shallow, you can install ceiling spotlight or horizontal spotlight). LED light source is more energy-saving and beautiful, normally LED downlight is diffusion effect and light angle is fixed.

2. LED spotlight

LED spotlight is also known as LED ceiling light, classified as built-in installed one and open installed one. Open installed spotlight is classified as sitting one and orbiting one. For built-in installed one, you need purchase as per reserved hole or open a hole as per purchased size, normally, the hole is about 7-7.5cm, smaller one is5-5.5cm or 5.5-6cm and bigger one is 8-8.5cm. Larger one is used in lounge ceiling and background wall, smaller one is used in cocktail cabinet, shoes cabinet and etc set. The hole of LED ceiling lightis relatively smaller than downlight and requires shallower depth of ceiling.

3. Difference between LED downlight and LED spotlight

Led spotlight has spotlight effect (LED ceiling light has diffusion light source), LED downlight is mainly used as subsidiary lighting in corridor due to its spotlight effect relatively to main light, its diffusion is 120°. LED ceiling light is mainly used to emphasize the atmosphere due to its obvious spotlight effect, it emits 30-60°, the angle of most light sources of LED ceiling light is adjustable used in picture and background wall lighting, or accent lighting surrounded the suspended ceiling.

Do you know the history of led lighting Products

The LED (light emitting diode), has a very long history. It dates back to as early as 1907, and is still evolving today. It took years to perfect the design and to make cheap led spot lamp products available in many different shapes and forms, so that it could become easy for consumers to buy it and use it within their homes and businesses.

Electroluminescence was discovered in 1907, by an experimenter and scientist from Great britain named H. J Round. However, there was no practical use for the discovery for many decades. Another inventor by the name of Oleg Vladimirovich Losev published an article on "Luminous carborundum (silicon carbide) detector and detection with crystals" in the Russian journal Telegrafiya I Telefoniya bez Provodov (Wireless Telegraphy and Telephony). Losev's work was not looked at for many decades, until in 1962, Nick Holonvak Jr., developed the first practical 'Light Emitting Diode' more commonly known today as LED or LED Lights. The first LED lighting products became available to the public in the late 1960's, and produced a red light. They were used mainly as indicators on laboratory equipment and in place of incandescent indicators.

In 1968, gallium arsenide was found to make the LED much more affordable and available to the public. LED lighting products were still very expensive; this meant that not everyone could afford LED. It was later discovered that adding a phosphide would make it much cheaper and still work just the same as the previously used materials.

As years went on, LED lighting became more popular and more and more people started to use this for other domestic appliances such as electronics like radio, television, telephone, calculators and even watches. LED technology was at its peak, as it was the most innovative product on the market.

The first LED screen was developed by James. P. Mitchell in 1977. The first display of the LED television was at an engineering exposition in Anaheim, in May 1978. This LED Flat panel TV display received a special award from such organisations as NASA, General Motors and the University of California Irvine, and a special mention was given by Robert M. Saunders, Professor of Engineering and IEEE President of 1977.

Low-cost, efficient blue LED's did not come out until the early 1990's. This is when the RGB colour triad was completed. This enabled new designs to be created for LED lighting products, these included new designs for outdoor signage and huge video displays for billboards and stadiums.

As the LED material technology became even more advanced, the light output was increased, and LED's became bright enough to be used for illumination such as LED downlights, LED flood lights, LED garden lights, LED street lights and many other forms of Warm White LED Flood light.

Most LED's were made in the very common 5mm T1-3/4 and 3mm T1 packages, but as higher power was becoming increasingly necessary, packages needed to become more complex to dissipate heat. Today, high power LED lighting products bear little resemblance to the early LED's.

Current LED lights are set to dominate the lighting market as they are highly efficient and consume very little power.

How to find best led outdoor flood lights 2013

If you’re in the market for finding the best outdoor flood lights for your home or business, this guide will help you. We will compare the cost, energy consumption, maintenance and longevity of three different types of flood lights so you can make an informed decision. The three types of outdoor flood lights are incandescent, compact fluorescent (CFL) and LED.

Incandescent Lights

This type of lighting is very basic in structure and operation. Generally, it is the cheapest type of light to purchase, but the lease energy-efficient. The light quality emitted from incandescent bulbs is the best of the three types, especially in flood lights that project light over a wide area. However, if you’re after a more diffused light, the incandescent bulb is not your best choice.

Even better than light quality is they are very inexpensive. That’s a good thing since you’ll be changing them often because of its high energy consumption. This type of light is the most expensive to operate. The average 60W incandescent bulb has the following qualities:

Lifespan: 1,200 hours
Watts of Electricity Used: 60 watts
Kilo-watts of Electricity Used: 3285 KWh/yr
Annual Operating Cost: $328.59/yr (or 30 bulbs)
(The flood light bulb is generally between 50 and 150 watts. The 60W bulb is used for comparison.)

Compact Fluorescent Light (CFL)

CFLs are much more energy efficient than the incandescent bulb and costs a little more. It produces a soft, warm light and uses most of its energy to produce light rather than heat. Even though you may pay more for the bulb, you save up to 75 percent in energy costs over the incandescent bulb to produce the same amount of light. That’s a great savings considering flood lights are generally used every night for several hours per night.

The 60-watt CFL has the following qualities:

Lifespan: 8,000 hours
Watts of Electricity Used: 13 – 15 watts
Kilo-watts of Electricity Used: 767 KWh/yr
Annual Operating Cost: $76.65/year
The compact fluorescent light is a big improvement over the incandescent light overall when used in outdoor lighting.
LED Lights

Our investigation places outdoor LED flood lights as the best to use in exterior lighting for the home or business. Until recently, LED lights were nearly impossible to use to cover wide areas because of their limited light range. However, improvements to their design have produced the wider range capacity needed and LED flood lights are now available.

That’s good news since you’ll realize even more energy savings with outdoor LED flood lights over CFLs. Here are the characteristics of a 60-watt LED bulb:

Lifespan: 50,000 hours
Watts of Electricity Used: 6 – 8 watts
Kilo-watts of Electricity Used: 329 KWh/year
Annual Operating Cost: $32.85/year
You’ll find the initial price of LED flood lights expensive compared to the costs of incandescent and CFL bulbs; however, you save so much money in energy usage and replacements costs that LED lighting costs seems almost non-existent in comparison.

This article set out to compare several qualities of outdoor LED flood lights with incandescent and CFL lights and found the LED type to be far superior in lifespan, energy efficiency and operating costs.

You might phone among the real estate agents for clarification in the occasion you do not realize a specific attribute.

MR16 9W Cool White LED Spot Light emits gentle from the item of stable matter

LED's - gentle Emitting Diodes - merely put, LED's are diodes that (huh?) hang on, I'll explain: a diode will be the simplest sort of semiconductor device. That's best suited - the red, yellow and eco-friendly about the site visitors lights are MR16 9W Cool White LED Spot Light best suited in top of your nose. In fact, gentle Emitting Diodes happen to be close to for some time, conceptualized in 1907.

However, it wasn't till the 1960s that sensible functions had been discovered and E27 9W Warm White LED Spot Light had been very first manufactured. LED utilized being utilized exclusively for site visitor’s signals, brake lights and car headlights on luxury cars, and indicator lights on appliances. You most likely didn't even understand that GU10 9W Warm White Spot Light These patents are standard within the artwork which characteristic attempts at tight, water resistant seals without any genuine emphasis on aiming or adjustment for your flood lumination to stay obvious of glare. When traditional 10W 16 color Flood Light are aimed at a focus on for being illuminated, glare is generally existing when a guy or woman appears in the direction of the supply within the 10W Warm White LED Flood Light. Fixtures taught through the earlier artwork do not have attributes for effortlessly adjusting the angle and path of illumination when the fixture is mounted (usually towards the ground) to stay obvious of this undesirable glare.
