1.  Q: Nearly all LED tube light look the same, in this case, how to know and judge the quality?
A: Price and exterior.
Though they look the same or similar, it is still easy to find the big differences in price and exterior. Price and exterior are two sides directly indicate the quality and they are mainly determined by raw material cost, for example, the cheaper led tube has fragile frame exterior, poor heat dissipation and driver with bad IC, MOS and capacitance. I know price is an important concerns for customers, it is difficult to sell if price too high. So, suggest you pick up the light with reasonable price, namely better price and cost ratio.
2. Q: Does T8 LED tube light really have 50,000 hours lifespan?
A: 50,000 or longer lifespan is only test theory data. The actual life is due to different working environments from in lab.
