How to Purchase led tube lighting?
we need choose the innocuity led tube,especially for indoor led home lighting.For the safe and environment,we need choos the LED tube lights has the reliable dustproof,dampproof, and material with fireproofing,NO ultraviolet radiation
When you purchase a LED tube lighting products,please choose longtech the CE,Rohs,FCC and UL led tube light,normally,they have the reliable quality, and quality testing report.For the Health,
1, capacity of T8 led tubes
Strong antistatic ability LED has long life,so the price is high too. LED should have the antistatic ability of 500V, then it can be use for LED Tube Lighting.
2, The wavelength of led tube
The same wavelength LED has the same color, Required LED has the same color,the price will be high，The led tube factory that do not have the LED color spectrophotometer is really to produce a reliable and same color led tube lightsDifferent brightness has different price. the led used for led tubes should be consistent with the standard Classa?? laser level.
3,Leakage current of led fluorescent tube
LED is a one-way conductive light-emitting diode, if there is reverse current,then we call leakage current, if the leakage current of led fluorescent tube is high,then the led tube light has the short lifetime and cheap price.
4,Light emitting angles of led tube light
Different angle LED used for different application.if you require a special emitting angles,then price will be high, Such as the diffusion angle LED tube lighting,it is high price.Life expectancy of led tubes
The most important of led tubes is life expectancy, lifetime depends on LED chip,Power supply,Driving IC,PCB..etc.so we need to use the reliable quality material for led tube lightings.
5, LED chip
For the light-emitting LED chip body, different chips,the price is different. Like Nichia LED Chip from Japan, Cree LED from USA, and some other LEDs from Taiwan China.
