LED Downlight

 cover material selection is a lot of non-standard companies as a means of reducing costs and  LED Downlight good quality products will increase in the use of anti-UV materials. Such as GE, Bayer and other materials, and poor quality of the lot LED guardrail tube outlet material using a mix of materials, not to mention anti-UV, sunlight relatively large areas, less than a month, the housing becomes yellow and thus the effect of variation of light, the light transmittance is also greatly reduced. 3, line loss many non-ferrous metal prices,

LED Strip

 the use of inferior materials and decreasing diameter are some of the manufacturers cost-effective way, the general good manufacturer will be used internally more than 1mm wire and wire material used is in line with the national standard products . If the wire size is not enough or too many impurities in the material, the resistance value is greater,

GU10 

in front of and behind the guardrail guardrail have a large voltage difference, to make the back of the LED can work, you need to increase the input voltage, so that virtually increases the power, not a lot of power to drive drive LED, but wasted on conductors and constant chip. Now a common constant current chip has power requirements, high voltage power consumption is large, if too much power, heat scattered out will lead to chip burned. This is why a lot of damage to the front LED tube are much why. 4, cooling general LED guardrail tube housing and the low seat is completely integrated, all plastic materials. When the LED arrangement is very dense,
