Things You May Want to Know About Flood Light

An overview of flood light

A coffee table book is an oversized, usually hard-covered book whose purpose is for display on a table intended for use in an area in which one entertains guests and from which it can serve to inspire conversation or pass the time. Subject matter is predominantly non-fiction and pictorial (a photo-book). Pages consist mainly of photographs and illustrations, accompanied by captions and small blocks of text, as opposed to long prose. Since they are aimed at anyone who might pick up the book for a light read, the analysis inside is often more basic and with less jargon than other books on the subject. Because of this, the term "coffee table book" can be used pejoratively to indicate a superficial approach to the subject.

In the field of mathematics, a coffee table book is usually a notebook containing a number of mathematical problems and theorems contributed by a community meeting in a particular place, or connected by a common scientific interest. An example of this was the Scottish Book created by mathematicians at Lviv University in the 1930s and 1940s.

What are the advantages of LEDs compared with conventional incandescent lights? of flood light

1 , high luminous efficiency the luminous efficiency of fluorescent is about 55 80lm / W, while the LED luminous efficiency is 100lm / W or more especially the high power LED light such as the PIRLEDFloodLight, and which will continue to improve as the technology continues to mature,half of the power LED lights can achieve the same luminosity of the fluorescent.

2 , high efficiency the efficiency of fixtures mainly refers to the effective optical efficiency , the fluorescent emit light in all direction , while the light emitted in the opposite direction is no avail , so by using a white lamp shade can put a considerable part of the reverse light reflected back. Therefore , the fluorescent lamp efficiency is only 70 %, while the LED is a 120 ° light, all the light is almost the effective light particularly for high power outdoor PIRLEDFloodLight , and the light angle may also need to be adjusted.

3 , high power efficiency case : 36W T8 fluorescent lamps, it's rated output power is 36W, after accessing the ballast , the measured input power is 42.4W, which is that the core inductance lost 6.4W and 85% of Efficiency declined, most of the power of the iron-core inductor is more than 10W , the power factor is less than 0.5 , and the efficiency of LED power supply is usually up to 30% , a 18W LED tube only need 20W input power, the power factor can reach more than 0.9 .

4 , long life the life of a high quality LED lamp up to 50,000 hours, the advantage of life span of the high power PIRLED flood light used for outdoor light and decorative light is more distinct, the fluorescent lifetime is usually only 5000 hours , the difference is nearly 10 times.

5 , no mercury, no pollution LED lights contain less harmful substances, which is a non- mercury pollution-free green light.

6 , the color temperature can provide almost any of a wide range of color temperature , and can provide the red , green, and blue colors of light as well as any kind .

7 , high CRI the CRI of fluorescent is 65 80, LED lights especially the PIR LED flood light can be > 80 , and no UV radiation.

8 , non- glass unbreakable , resist the impact, vibration.

9 , safety the power supply of the LED light is external isolating power , only less than 36V DC is safe voltage , which reduce the risk of electric shock and is a relatively safe lamp.
