When you decide to buy HID xenon lamp, the quality in the end do not know how, refer to the following method may be simple to identify.

1, look at packaging, suggested the use of domestic legal trademark brand of Chinese products, there should be instructions in Chinese, it is clear to see on the packaging to manufacturers and contact information in the manual and warranty card printed on the manufacturer's contact details, will be no more than included in the three products.

2, see the ballast, it must be a metal (preferably aluminum, helping to heat) must not be plastic; because the plastic is not high temperature and slow cooling of electronic components have a serious impact, the ballast largely determines the quality can be said to complete the quality HID xenon lamp.

3, see the cable, should feel very soft and thick enough, and the sets have insulated pipe (PVC pipe and heat-shrinkable tube), indicating good quality wire, not aging. But not reflected on the above lines are a good group, can be used to check whether the national standard line set the standard, compliance with safety requirements; line if too small, or wire texture, not very good, please choose carefully.

4, to see a variety of connectors, feel the texture is good, whether it is with a waterproof pad, or likely to cause a short circuit phenomenon.

5, see the light bulb and wire insulation, integrated package after the heat-shrinkable tubing than good.

6, to see whether to provide ballast bracket (regular manufacturers have provided more than safe and reliable adhesive), except for individual slim ballast.

7, wiring electricity experiment, to see light speed, to about essentially the same light and fast enough, it should be in 5 seconds or less basic to full light.

8, frequently switch a few times (every 10 seconds or more), start the speed should be the same or faster.

9, so light work for 30 minutes, to see whether there are significant differences in color temperature, ballast is hot (it should be warm, the temperature about 45 degrees, if you feel hot, and that this poor quality of the ballast material to be used not well, it is recommended with caution), holder (not bulb) is hot, the wire is heat; If the wire has fever phenomenon, this quality should not be a quality product, recommended caution.

10, turn off the lights two lamps are basically the same speed, so if there is a significant difference, indicating that product quality is not very good.

11, the last one is critical, many consumers believe that well-known international brands or imported products. But in the choice of brand-name imported products must be careful attention, in general, imports of HID xenon lamp ballast are thin, smaller thin. The manual process is generally very good, rather than a thick paste of a Philips ballast above the standard is genuine, consumers in this area must be carefully chosen to buy a friend, and now there are some 4S store of Sales of imported brands are not necessarily full-xenon lamp is genuine. Because it has been tampered with in the business, it is recommended that consumers carefully chosen friends, made of HID Xenon lamp is not an absolute good, but there are very few unscrupulous merchants supply some of the low-cost low-quality products. Suggest that the majority of consumers, distributors, agents in the choice of products, suppliers, when we must choose to protect businesses and products
