Advantages and Disadvantages of LED Tube Lights

16 Jul

LED tube lights are designed with the latest LED lighting technology and high efficient LEDs, and they are supposed to replace conventional CFLs which are widely used for commercial lighting and residential lighting. Why LED tube lights can replace conventional CFLs? What are the advantages of LED tube lights? LED tube lights feature many advantages when compared to CFLs.

LED tube lights are of high energy efficiency. LED tube lights adopt high efficient LEDs as light source, which can achieve a luminous efficacy of 100 lumens per watt. Therefore LED tube lights can deliver the same light output as CFLs do while just consume 50% energy as CFLs do, which means by using LED tube lights to replace CFLs you will save over 50% energy bills.

LED tube lights can last over 50,000 hours, which is as ten times as the lifetime of CFLs. LED tube lights are solid state lighting fixtures, so they can last much longer than conventional lighting fixtures. During their lifetime, LED tube lights hardly need any maintenance, which will greatly save your maintenance costs. Meanwhile, you don’t have to replace bulbs frequently since they can last more than 10 years, and the bulb replacement costs they save for you can be also very considerable.

LED tube lights are green and eco-friendly lighting fixtures without any hazardous materials such as mercury and lead. They will not cause any environment pollutions when they are disposed. Unlike CFLs, LED tube lights do not emit IR or UV radiation, and they do no harm to human beings’ health.

As a matter of fact, LED tube lights are far more than the above mentioned advantages. However, LED tube lights also feature some disadvantages. LEDs are currently more expensive, price per lumen, on a startup cost basis, than more conventional lighting technologies. The additional expense partially stems from the relatively low lumen output and the drive circuitry and power supplies needed.

LED performance largely depends on the ambient temperature of the operating environment. Over-driving the LED in high ambient temperatures may result in overheating of the LED package, eventually leading to device failure.

LEDs do not approximate a “point source” of light, so cannot be used in applications needing a highly collimated beam.

    so nice post…
    Obviously, LED tubes are not able to be widely used at homes right now (price is still the biggest obstacle), however,
    we’ve been seeing more and more interest of LED tubes in the commercial sectors.
    I have some clients are doing some LED tubes replacement projects for the schools (universities), and some are doing some projects for some supermarkets.
    And many of them are showing much interest of our dimmable LED tubes.
