1. Check the light bulbs the size of the package whether or not the production of Make, address, telephone number, the implementation of standards, a trademark brand, packaging design, printing is exquisite, beautiful, understanding of the species is a well-known brands supporting automobile plant.
2. Appearance: visual filament, lamp cap, the bubble should be the correct symmetry shell assembly; spot firmly smooth, bright lamp, no scratches; bubble shell transparency, and no gas lines, air bubbles; filament rules, clean, non-deformation; wick tidy skew of no more than 5 degrees; bubble shell and the head is not connected to the exposed adhesive, adhesive evenly; lamp Seal typing clear, there are grades, specifications, and some of its products are certified batch.

3. Mechanical strength: The right hand (wearing gloves), respectively, and the bubbles take lamp cap screw shell like (force of not more than 15N), understand the lamp cap and the foam adhesive is a solid shell; will bubble shell above the air-kissing木桌and gradually forced to determine the bubble shell The thickness and strength; lamp with fingernails by skin and foot card to see if the deformation to determine the strength.

4. Optical parameters: conditional detection instrument bulbs available in current, luminous flux and life span, whether the parameters of the standard indicators, to determine whether or not qualified.

5. When the average consumer to buy light bulbs, light bulbs have the characteristics of the first three can be eligible to buy goods.

The characteristics of poor-quality light bulbs

1. Packaging design system so rough, imprinting is not clear, no Make no address, no telephone, no implementation of standards.

2. The appearance of dirty, black filament, twisted, with black or dark lead oxide red, lamp cap has rust, dull, with a clear Waitoushan, askew and askew shoulder batteries, lamp without typing or typing Seal only non-grade specifications.

3. Low mechanical strength, the bubble shell thin, fragile, thin head, legs and head skin with a fingernail or by collapse and bubble lamp cap shell or uneven adhesive exposed.

4. Most of all kinds of photoelectric parameters failed.

Identification of light bulbs do not sloppy effect

1. Not heard of the new varieties to a deeper understanding, can not be easily purchased, such as such as "halogen vacuum bubble" such as those of the pure fakes.

2. Use at the time of purchase to find out the bulb, look for whether the car light bulbs, which parts of the automotive light bulbs used. The effect must not be perfunctory.

"Search Light" is a member of my auto?

"Search Light" for its high-power (100Wx2), strong condenser, the advantages of irradiation distance for night-time long-range search, observation or special areas of recovery. In recent years, the search lights openly in many parts of cars and farm machinery store home security.

Some lawless elements of the consumer to know the truth advocate its high brightness, according to Cheng Yuan, inducing consumers to buy and install in their cars, tractors and three-wheeled agricultural vehicles, used as a headlamp.

As the "search light" an exceptionally strong eye, seriously affect the traffic safety at night, it is necessary to stop using. Standards of the country to promote the use of headlight dimming of the light bulbs, including R2 and H4 series, its performance illumination dimming values and traffic safety requirements are met. To remind consumers to identify the use of certain attention to prevent any eventuality.

A "vacuum bubble halogen" it?

Some of today's auto market appears "Halogen vacuum bubble" is actually "vacuum bulb." Vacuum light bulb family is making the most simple process of species, with the inflatable bulb compared to a shorter life-span, low flux. "Halogen bubble car" is the tungsten halogen cycle in accordance with the principle of making to improve the brightness and extended lamp life, and in the production process, the first light bulb by vacuum pump into a vacuum, and then charge into the appropriate halogen element, and then charge into the amount of nitrogen over-voltage or helium. Halogen bubble due to the high brightness with long life advantages of the current used in automotive lighting headlamps, fog lights, halogen lights, etc. have been replaced by the bubble, the bulbs should not be referred to as the "halogen vacuum bubble."

Speculators taking advantage of some consumers do not know much about the case of light bulbs, the introduction of the so-called "vacuum bubble halogen" is to use fake fraud to remind consumers not deceived.
