5.FAQ

We have organized several common questions for our clients，may help you sincerely：

①How about your company？

A world class manufacturer & supplier of castings forging in carbon steel and alloy steel，is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

②How to guarantee the quality of the products？

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide how to success.

Q: What are the types of LED bulb?: The LED bulb replacement use convenient, makes this type of products are widely accepted by users by the family, under the same illumination conditions choice to replace the traditional lighting.

Q: What are the requirements of the LED series inspection specification for bulb bulbs?: The temperature rise of the finished lamp is not more than 120K. The temperature rise is equivalent to the maximum value of 60W incandescent lamp.

Q: LED can the bulb be used in the bathroom?: From a long-term perspective is not enough, you can choose a lamp are closed, such as ceiling lamps what, now have special indoor lamps, but you must not use ordinary lamps, because LED lights to the heat at the edge of the open slot or empty, easy water.

Q: What are the characteristics of LED bulb?: Less power consumption, a 5 Watt LED bulb, equivalent to 40 watts of ordinary incandescent.

Q: 60W how many lumens and how many W LED bulb does incandescent bulb replace?: 100lM/W LED bulb, 4-5W can be replaced. If it is white 4W can be, if it is warm white (yellow light), preferably 5W, mainly human eye feeling, white light than Huang Guangliang.4-5W LED bulb, equivalent to 12-15W energy-saving lamps

Q: Are there any differences between negative ion bulb and LED bulb?: The negative ion belongs to bullshit type, the concept of things!

Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!: If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem

Q: What brand of LED bulb is good in quality?: View brightness. Incandescent lamps usually only talk about wattage instead of lumens, but LED bulbs can count in watts, but wattage does not represent the number of lumens due to the continuous development of LED's luminous efficiency.

Q: What's the difference between a glass cap for a bulb and a PC hood?: ProcessabilityMachinable, blister, special-shaped processing PC easier.

Q: Is there any flicker in the LED bulb?: Really, the voltage in our home is likely to lead to fluctuations in the LED bulb strobe in public, voltage instability will be more common, but most of the voltage is relatively stable, does not appear large fluctuations, so the strobe is not violent, but the fact is there. Questions raised by the questioner can show that you are observant.
