LED tube demystify

LED tube is a newly emerging product from China. They typically have aluminum back half tube, diffuser from tube cover, LED PCB and driver circuit. The whole thing is packed inside a narrow long tube that has less than an inch in diameter, compatible size as fluorescent tube in order to retrofit. LED tube usually use many small low power LED, typical hundreds of them. Because the distance between LED and diffuser is less than half inch, to make the light output look uniform, the distance between LEDs should be less than that too.  Depends on the design, a typical 4 foot long T8 LED tube uses 18W ~ 22 Watt of power, is less than average 32 Watt used by fluorescent tube to achieve same brightness..

Although the goal was to retrofit into existing fluorescent light fixture, there is a ballast between household AC and fluorescent tube connectors to reduce current in  fluorescent system. Install LED tubes into fluorescent fixture need to bypass this ballast, and there are two kinds of LED tube standards that's not compatible with each other. Mix use these two may cause catastrophic damage and dangerous. Therefore remove or bypass the fluorescent ballast is considered invalidation UL warranty.   

Put that aside, diver used in LED tube has to be crumple inside a tiny space that's less than half of tube. So their design is usually delicate. Since both of LED board and driver generate great deal of heat in such a close proximity, they affect each other in many aspects. There are reports about poor lifetime of driver and color degeneration of LED at near the driver.   

On the contrary, Easy LED kit or lamp use external driver with good safety and quality, and our module handles heat excellently, we believe is a much better choice than LED tubes. Easy LED kits and Lamps can be get at easyledlighting.com
