Do not be led tube lights lighting industry price war lost eyes teach you how to distinguish quality T8 tubes
led tube lights lighting lamp tubes t8 t5 mcob tcob cob review: led tube lights price war has now sold like cigarettes everywhere, and product quality is uneven, a 1.2M led t8 t5 fluorescent tubes from ten yuan to the hundred, but has nearly ten times the appearance of similar spread. This is the middle what kind of difference? How can consumers come to judge the quality difference? Low price and good quality can really do it? The presence of cost and quality balance it?
OFweek Reuters lighting led tube lights price war has now sold smoke everywhere, and product quality is uneven, a 1.2M led t5 tubes fluorescent tubes from ten yuan to the hundred, but has nearly ten times the appearance of similar spread. This is the middle what kind of difference? How can consumers come to judge the quality difference? Low price and good quality can really do it? The presence of cost and quality balance it? Today, with an opportunity for fifteen years in the led tube lights industry technology, a senior engineer Li (hereinafter referred to Li Gong) common random reviews dismantling a good reputation in Shenzhen factory led tube lights T8 fluorescent tubes. This is a common market of plastic tubes, the same look and the market average plastic lamp, we first tested using an integrating sphere photoelectric color parameters:
Obtain its parameters: Power: 17.3W; PF: 0.52; flux: 1711.2LM; luminous efficiency: 98.92LM / W; CRI: 73.5; color temperature: 6516K.
“In addition to lower PF value of some other parameters are good middling light effects, to see the materials used.” Lee to work according to its data evaluation. Its cap to snap, the ease of assembly and maintenance, without the aid of any tools can be easily opened. Plus an aluminum inner tube (commonly known in the industry: plastic clad aluminum), which can solve the heat problem led tube lights, can effectively delay the light fades, to extend the lamp life effect. On board with the overall structure of aluminum plate heat well. Li Gong took the board looked at carefully when it comes to “It should be 1016 GB substrate material good. After the first line and a string of lamp failure will not affect other lamp beads.” The T8 tubes use 96 28350.2W lamp beads, closer to detect lamp beads quality, Li Gong holding magnet on the lamp beads, lamp beads further testing material, but does not reflect light beads. Holding the ferrochrome lamp beads taken down with scissors scratch bottom plating layer holding forceps inside the lamp beads colloidal singled tube lights out in under an electron microscope observation for a while, he said: “clearly the copper bracket, gold wire, chip size is not visually It will be less than 10 * 20 lamp beads really good. “
Another core tube: Power
Based on a comparison of a variety of brand power, and Li Gong judgment based on test data, the power of this basic protection functions: over-temperature, over-voltage, open circuit, short circuit. And confirmed the decision of lamp life is the use of domestic Kaiser GATHER 105 degrees 5000 hours, the power supply voltage 4000V.
Overall, this lamp materials more moderate, we do the following tests, in-depth assessment of its real life:
According to our capacitor operating temperature and the relationship between life test (if the capacitor operating temperature of 105 degrees on the basis of ten degrees to decrease life expectancy doubled tube lights) is its operating temperature is 95 degrees, there are ten thousand hours, 85 degrees fifteen thousand hours, twenty thousand hours to 75 degrees, 65 degrees is twenty-five thousand hours. At ambient temperature twenty degrees when its operating temperature is below 65 degrees, when the ambient temperature to 41 degrees heightening its temperature is 68 degrees. That day, 365 days a year in accordance with point 16 hours counted, the theoretical life expectancy is four and a half.
Li Gong depending on the material and the test results for this product
Summary: Disadvantages: general appearance, PF value is low, single voltage (170-265V) can not EMC and safety regulations;
Advantages: circuit boards and power supply and the amount of light beads three core reality, product quality and stability, high efficiency, uniform light, no flicker no damage to the eyes (2.5) years of normal use light decay should be less than 15%.
Li Gong according to the market probably to estimate what the costs: housing 6 yuan, PCB2.2 yuan, lamp beads 98 * 0.08 = 7.84 yuan, 2.5 yuan power, labor costs 3 yuan, 1.8 yuan package, as well as loss of rent utilities and administrative costs etc., the total cost should be around $ 25, plus 20% of profits under the current led tube lights market and the widespread use of a price war in the larger environment, this lamp market price should be around 28 yuan. ”
