Now LED lamp line design is full of beautiful things in eyes, many manufacturers to promote their business, the line of light are of good quality, low cost, long service life, etc., and some of the high cost of "brand", whether we want to how to distinguish the stand or fall of line lamp, from which points to the analysis, here small make up this problem to collect a large amount of information to to you.

Analyze the quality of line lamp from five points of foundation
Article 3 in the first, look at the pictures, this is unused product, same line lamp, paragraph 1, line light from that small workshops to buy installation at the edge of the river bank for contour lighting, have been used for a year, with yellow so brightness is not meet customer's requirement, so has been removed, this is a customer sent us a sample. (LED Lights Manufacturer from China)
Type 2: the line lamp is a line lamp that has been tested in an outdoor environment for one year after the surface dust is wiped off.
Paragraph 3: just do it has not been put into use the line of light and everybody saw this article 3 line lamp difference so big, I'm sure you don't know when their appearance may be identical, so how are we to distinguish to avoid buy inferior line lamp? (LED Lights Manufacturer from China)
Line first, to see the glue: (1) the lamp in the year there is such a serious phenomenon of yellow because of poor glue materials, there are a lot of in the name of the waterproof PU adhesive to sell inferior glue, waterproof properties is poor, easy yellowed dimmed, the same as normal, it is waterproof PU glue the prices are far, basically is more than double the price.

Second, the aluminum: ultra-thin aluminum flexible type, choose in line light aluminum, the formal manufacturers will first consider the heat dissipation performance is good, whether you think the thicker the aluminum, the better?
Actually not, the makeup that you change, powdery bottom thicker more good-looking?
Certainly not, aluminum if you want to do it is not easy to deformation, good heat dissipation, must choose moderate thickness, cannot say blindly want the thicker the aluminum, the better, if the line light aluminum heat dissipation, the better the thinner?
The thinner the aluminum, the worse the heat dissipation, the easier it is to be extruded and deformed when installing.
In addition, it is a question of cost performance. If you want to have a high cost performance, the manufacturer must control the materials used well. (LED Lights Manufacturer from China)
Third, see light bead components: in the industry, so several packaging manufacturer big names, what career - pury - day - Taiwan wafer and so on, but can you tell if this is you get the chip brand?
Some lost conscience line lamp manufacturers how good his quote billed as raw material, with a few cents to pretend to be a big brand of chip to sell, but the price law in fact, what good could buy cheap goods?
Customers are also deluded and willing to be cheated. (LED Lights Manufacturer from China)
Some lights, domestic brands, after years of testing and improvement, their craft and play is also very strong and stable, according to the project cost you can choose a few domestic good brand, such as three, this brand is good too. (LED Lights Manufacturer from China)
The 4th move, see the choice of circuit board: aluminium base board can be better than glass fiber board certainly?
Really good quality line lamps, most of the use of aluminum substrate as a light source circuit board.
Have fiberglass panels been labeled inferior?
This is not yes, I also think the product is high quality product of glass fiber board, then after the technician explanation, also know that glass fiber board has good or bad, you can even better than the quality of the aluminum plate, as long as the steady, aluminum plate and glass fiber board, they are all good circuit board.

Fifth, the waterproof plug: the LED market is really big, every year, customer consulting a: "do you have any new prices this year", there are some manufacturers are under the pressure, will cut a little on material, but there are some manufacturers to lower profits to maintain existing customers, waterproof plugging are cheap, but relatively conductive is bad, and waterproof properties is poor, easy to cause the water leakage, square head basically four core plug is also very good though its price is higher, but overall stability can reach 99% waterproof, that 1% is likely to be not tight.
