9 points affect the price of LED lamps

There are many manufacturers of LED and LED lighting . Different manufacturers use different quality LEDs, which is an important reason for the different price of LED lighting. Due to the increasingly fierce price war, the products with almost the same appearance, structure and function have a price difference of 2-3 times. Many users have been stunned for a while, and they do not know where the price difference comes from. Generally, LED lighting manufacturers that do not produce LED lighting tubes are generally not produced. It's hard to distinguish, let alone consumers.

Therefore, it is better to choose a LED lighting factory that has a good LED production source or a complete LED testing equipment, so that the bought LED lighting products will be more secure.

Let's see what factors are causing the price difference of LED lamps:

1, brightness
The brightness of the LEDs is different and the price is different.
2, antistatic ability
LEDs with strong antistatic properties have a long life and are therefore expensive. LEDs with an antistatic greater than 700V are usually used for LED lighting.
3, wavelength
LEDs with the same wavelength have the same color. If the color is the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
4, leakage current
The LED is a unidirectional conductive illuminator. If there is a reverse current, it is called a leakage current, and the LED with a large leakage current has a short life and a low price.
5, the angle of illumination
LEDs with different uses have different illumination angles. Special lighting angle, the price is higher. Such as the full diffusing angle, the price is higher.
6, life
The key to different qualities is life, and life is determined by light decay. Low light decay, long life, long life and high price.
7, LED chip
The illuminator of the LED is a chip, and the price of the chip varies greatly. The chips in Japan and the United States are more expensive, and the price of LED chips from Taiwanese and Chinese manufacturers is lower than that of Japan and the United States.
8, chip size
The size of the chip is expressed by the side length, and the quality of the large chip LED is better than that of the small chip. The price is proportional to the chip size.
9, colloid
The colloid of ordinary LED is generally epoxy resin, and the LED with anti-ultraviolet and fire retardant is more expensive. The high-quality outdoor LED lighting should be resistant to ultraviolet rays and fire.

There are still some illegal people in the LED lighting market, deceiving suppliers, defrauding suppliers of materials to produce finished products, and selling finished products at abnormally low prices in exchange for cash. There are also a handful of LED lighting manufacturers that deceive dealers and users with unrealistic promises, and then use the tactics of constantly changing the firm or the person in charge to shirk responsibility.

Mechanical Timer

24 hours mechanical Timer
Instant indicator
Min.setting time:15 minutes. Max.setting timer:24 hours
With hand switch,can be switched to operating and

setting at any time

Instructions:

1. Set program: 1 pin is equivalent to 15 minutes. Determine desired start time and push down pins until desired
off time.
For instance, if you want electrical devices to work from 8:00am to 11:00am and from 13:00pm to 17:00pm, you
just need to put down allthe pins between the three period time.
2. Set the current time: Turning the dial clockwise until the arrow pointing to
current time.
For example,if now it is 8:00 am, please turn the dial and make sure the
arrow point to 8. (See the picture.)
3. Plug the electrical device directly into the timer. Make sure the electrical
device is power-on.
4. Plug the timer into electrical outlet and the electrical device will be work
according to the setting program.
Note: = Normal Ope n = Timing
Make sure the switch on the Timing position. If it
is on the [Normal Open" mode, the electrical device is
always power-on and the timer function no work.

Specifications:

Caution:
1.D o not exceed the maximum ratings of the timer.
2.M ust reset the current time after power failure.
3.D o not plug the timer directly into the working electrical appliances.
4.U nless changing the setting, keep the program same every day.
5.D o not disassemble timer by yourself. Professionals service are needed for maintenance.

6.T his item is only for indoor use.
