Nowadays, LED lighting technology is setting off a whirlwind of industrial revolution. LED lighting bulb manufacturers are working to quickly improve performance and reduce the price of LED bulbs . Last year, ordinary family-style LED bulbs, such as A19LED bulbs, were priced between $20 and $60, and were already very cost-effective. This year, high-end LED bulbs, such as LG's LED bulbs, are priced as low as $10, breaking the "10" just around the corner.
The performance of LED bulbs is similar to that of fluorescent lamps (CFLs), 50-60 lumens/watt. Despite this, LEDs are still technically superior to CFLs. The 7.5WLG bulb emits 485lumens, which is equivalent to 65lm/W. Under the same 485lumens premise, the old 40W bulb can only emit 12lm/W, which is about five times less than the former.

About uniform lighting problems
When we place a desk lamp with an LED bulb, we can control the brightness of the lamp to illuminate upwards. This is because the inside of the LED emitter is placed horizontally. The Philips bulb uses three vertically adjustable LED faces to slow down the control of illumination brightness. Despite this, the uniform illumination of reading lamps or work lights makes it impossible to concentrate heat on a certain lighting object.
As shown in the figure, the LG bulb can control most of the light to be projected upwards because the LED substrate is placed horizontally inside the bulb.
The design of the desk lamp evolved from the principle of the Edison bulb - the emission of light is scattered in all directions. With the evolution of light bulbs for more than a century, modern lamp design and its pioneer, the kerosene lamp, look very different.
The original bulbs did not have mandatory requirements in terms of efficiency and popularity, but their advantages led to their prevalence and led to the decline of oil lamps. One day, the electric light will develop into a product that adapts to the uniqueness of the LED light source. This day is not far from us. When LED light sources can improve their service life in the next decade, it is undoubtedly a replacement for electric lights, and the lamps will have a variety of specifications and shapes. At the same time, forcing LEDs to take Edison's style version is tantamount to punching a square nail into a circular hole.
However, StrategiesUnlimited predicts that the global market share of the traditional light source being replaced will rise to $3.7 billion in 2016, and this figure is still 2.7 billion in 2011. In fact, LED tubes provide very comfortable brightness, as opposed to A compact fluorescent bulb will make it more enjoyable and people will be willing to use it. These bulbs are more durable than CFLs, do not contain a watermark, and light up as soon as they are turned on. Those nasty CFLs take a while to reach their maximum brightness.
LED tubes are a complex electronic device. The LED itself is a semiconductor diode that requires only a DC voltage of approximately 3V. Ordinary households are powered by 110V or 220V AC depending on the geographical location. LG's lamp can't adjust the brightness. Although new models of dimmers are required, the relatively high price of the product is adjustable. Like the CFLs, the LED tube has a small circuit board housed inside the "neck" of the tube.

An electrical appliance used to protect electrical equipment from high transient overvoltage hazards and to limit the duration of continuous flow.This term includes any external clearance necessary for the normal functioning of the appliance during operation and installation, whether or not it is a unit as a whole.
Surge protector, also known as lightning arrester, is an electronic device that provides safety protection for all kinds of electronic equipment, instruments and communication lines.When the electric circuit or communication lines or for outside disturbance suddenly produce peak current in voltage, surge protector in a very short time conduction tap, to avoid surge damage to other devices in the circuits.[1]
Surge protector, suitable for ac 50/60 hz, rated voltage 220 v to 380 v power supply system, the indirect lightning and thunder and lightning directly affect transient over voltage surge protection, or other applicable to the family home, the third industry and the surge protection industry requirements.
