Why are some energy saving lamps sold a few yuan, 20 yuan more than a dozen others to sell?

The determination of a cost-saving lamps are many factors we must weigh the cost of the following conditions: 2U9W energy saving bulbs do cost comparisons and performance comparison.

1. Capillary

Poor quality glass, hair usually loaded with goods manufacturers, defective products, poor product quality is equivalent to higher capillary only 1 / 3 to 1 / 5 the price.

Ordinary phosphorus halogen phosphate, the calcium phosphate theory that the brine is not used for lamp phosphors fluorescent energy saving due to their efficiency in low light, the color rendering index is low, does not apply to a large lumen diameter less than 30 mm lamps fluorescent, is priced at 30 yuan / kg yuan 1.

other filament materials, such as manufacturers of electronic dust has been buying shoddy goods, defective, or no quality assurance of small factories.

As manufacturers capillary and crudely, you do not need technical staff, managers, technical staff and equipment.

The product sold at 0.9 yuan Or something.

glass tube top quality, the capillary is generally excellent product manufacturers or first class products.

three phosphors with high efficiency, compared to halogen phosphate phosphorus, which has a high luminous efficiency, color high rendering index, light a small decrease, it is applicable to fluorescent diameter less than 30 mm but not more than 30 mm lamps fluorescent, is priced at 800 yuan / 1 kg yuan.

To ensure the quality manufacturers in the technology, quality management process, and the team is very hard.

This product is sold at 4 yuan or less.

2, lamp holder plastic

lamp manufacturers used inferior materials, manufacturers of lamps same as the iron lamp without reservations about 0.03 yuan / support, and that does not meet national standards (size, rust-proof capacity) will be during its use is not bolted to the light within the block, or bolt easy to fall.

Plastic parts are plastic ABS, prices lower than the plastic ones were small, the heat resistance and flame resistance are poor, it is easy to fire.

It costs about 0.25 yuan each on the energy saving lamps.

lamp manufacturers use the product iron equal quality or level (national standard) cost around 0.15 yuan / only

PBT plastic flame retardant engineering less than 180 in the temperature to work long hours without distortion, and good flame resistance.

costs one yuan each.

3, electronic ballast components

circuit board does not have a flame retardant used in circuit board, this board book, with a poor effect of copper, copper switch easily lead to skin.

take advantage of electronic components such as resistors, diodes, capacitors are generally the same with some of the regular factory production line from one station to play down the unskilled, or some no-name manufacturers, and those dollars to buy a bunch of press kits to take advantage of the rule, some with tons of the standard.

For some transistors, coils and other items also are free to buy some small manufacturers, product quality and unprotected, but no management functions, and not go to selection.

the cost of the components of an electronic ballast are mostly 03.02 yuan.

circuit with a flame retardant in circuit boards, such thickness of the circuit board with a bronze effect, high temperature, without distortion, skin copper shaft rocking in a prone position.

electronics manufacturers have generally adopted a formal capacity assurance quality manufacturers of product quality, or first-class products. Buy this component for calculating the overall payment in the first place.

for some of the most important components, such as electrolytic capacitors, transistors, etc. are generally used in the import, or manufacturers national capacity to protect and plant selection to match the sub-parameters.

components of an electronic ballast costs about 7 yuan.

4, prior art

basically no staff technical, even if there are some relatively poor, while there is no test instruments, meters are not capable of development, only one copy of a copy of style.

technical staff are very good quality and experienced.

test instrument, apparatus, are relatively complete.

with new product development capacity, according to the different raw materials with different parameters to adjust.

5, production conditions and quality status

production only original purchase to assemble, light OK.

Because it is funded by piece, without any management, supervisory staff quality. What the production does not require equipment, aging equipment, testing equipment.

processing costs of about of 0.1-0.2 yuan.

production is subject to checks at each level, filtering, sorting out the original device from time to time, in accordance with the procedures of a process produced.

As a result of the assembly line more efficient, quality control tighter, the production equipment, test equipment, more complete.

Save Product to go before the final factory.

processing costs 1 yuan.

6, integrated

Integrated into the analysis, we can see that the lights low power consumption can make a few dollars, but it is a waste treatment plant to refuse to buy back for processing and assembly, and then sold to users. Consumers can buy back the waste and fire problems.

Good product manufacturers from the above analysis is in line for the sake of users, generating a cost of high performance products for the user.

Fourth, the performance of energy saving lamp:

Safety: circuit board, wires, coil materials high temperature flame is used, the shell material (BT, the factor most powerful line of 0.9, the third harmonic content is low (less than 12%) in the network and other computers without fault line.

life: the average life expectancy of more than 7000 hours and one year warranty.

tricolor fluorescent lamp high-efficiency, water powder coating, coating technology made color index of 80 ±

About 5, color tolerance 5.

electronic components are made from ballast manufacturers quality assured, the key components in the products using the original device, double-wave machines welding to weld, and gradually began to Applications SMT technology.

Plug-bubble pipes imported revive the fast, long life.
