First: LED fluorescent tube failure problems
It was generally felt LED tubes did not feel so bright, in fact, that is the LED tube color rendering index of the problem. CRI is not high enough brightness illuminated by the LED lamp is not high, the feeling is soft feel.
Second: LED tube irradiation is not in itself the true colors
General market purchase of tube color is white and warm tube, white tube will feel like Blu-ray, because there is a fluorescent material irradiation heating will produce complementary colors on the tubing.
Third: LED lamp life is not so long that you think
Life in general business promotion LED tubes will reach 50,000 and 100,000 hours, by the technical staff to detect generally only 20,000 to 30,000 hours. This and drivers have a great relationship, constant current regulator will stabilize to some extent driven by the normal operation and prolong life.
So the price is by no means a measure of LED lamp standards, or to understand the overall performance parameters when buying, make the right choice.
