The Benefit of LED Tubes Replacement

Back to 3 or 4 years ago, if someone talked about LED tubes, we may probably have no idea what it is about. But now, when we look around, we could probably see that LED light tubes have become a very hot topic and have been becoming more and more popular year by year or even day by day. The traditional fluorescent lights are widely and typically used in different lighting applications such as industrial lighting, warehouse lighting, commercial lighting, office lighting and residential lighting etc. But nowadays, it seems the moment to consider about replacing them with LED light tubes.


LED or referred to as Light Emitting Diode is environment friendly as they generate light by the movement of electrons in the diode. Comparing with LED, florescent lights waste most of energy to produce heat which are definitely no good to our environment. A typical LED light tube may include hundreds of LEDs. The actual number of LEDs depends on the size of the tube or the illumination requirements.


There area a great deal of positive aspects that drive people to try and make use of tube LEDs. For example:


- Can you imagine how much heat a fluorescent tube light can produce? Have you heard about the complaint made by those people who have to sit or work underneath or near fluorescent tube lights – haven’t mentioned that some of them claimed to suffer from frequent head aches. Not like the conventional fluorescent lights LEDs will not produce much of heat and they would not cause people any head aches. LED lights can be installed wherever you want them to be, living rooms, bedrooms, halls, buses, trains, boats, cabinets, etc. And of course, you may have probably notice there are some Christmas lights and curtain lights that are made of LED lights.


- LED tubes consume 60-70% less energy when in comparison with the fluorescent tubes. Typically, a 20W fluorescent tube can be replaced by a 8-10W LED tube; a 40W fluorescent tube can be replace by a 15-18W LED tube; a 60W fluorescent tube can be replaced by a 24-26W tube LED. And please keep in mind that if taking the ballast and starter into account, the tube LEDs can save even more energy as unlike fluorescent tubes, LED light tubes do not need any ballast and starter.


- LED tubes are available in different sizes and colors (in a more technical way of description, it means color temperature). Currently, LED tubes follow the traditional design of traditional fluorescent tubes (T5, T10, T10, T12 etc). The reason for that is to allow direct replacement of the existing fluorescents without extra retrofit cost by replacing the whole lighting fitting. As a result, the commonly obtainable sizes of LED tubes (take T8 and T10 for example) are 2 feet (600mm), 3 feet (600mm), 4 feet (1200mm) and 5 feet (1500mm) and 8 feet (2400mm). Another advantage it should be looked at is the diverse colors that LED lights can produce. Back in the fluorescent tube ages, the light color of a fluorescent tube can not be chosen. But now, with LED fluorescent tubes, the light color can be cold white, pure white, natural white, warm white, red, green, blue, yellow etc, extremely flexible and user-friendly.


- LEDs have much longer lifespan when compared with other lights. Theoretically LEDs’ lifespan can be as long as 50,000 to 100,000 hours. Of course, when it comes to a lighting fixture, the lifespan is not only about the LEDs, but also related to all other electronic components of the lighting fixture. However, this is the way how LED tubes can help to save your maintenance bills for failed lights replacement.


Despite the fact that there is variety of advantage of LED tube replacement, consumers tend to concern about the downsides. Below would be some of the most concerned drawbacks of LED light tubes:

- One of the major problems (and probably the biggest one) that bother the consumers is its price. LED tube lights are much more costly when in comparison with the fluorescent tubes and incandescent bulbs. The market prices normally vary from $50 to $100. However, considering the LED tubes can work for an prolonged time, the cost is acceptable, especially to those commercial applications that need long-time running.


- Retrofit work could be another issue which is concerned, as you may need to reset the electrical configuration in order to let the tubes work properly. The conventional fluorescent tubes require ballasts and starters which are not needed for the LED tubes. Therefore, ballasts and starters will be removed when installing LED tubes. This means a little extra rewiring work.


To summarize, the pros of utilizing LED tubes are considerably much more when compared with its cons. Its worth to have a try of tube LED replacement.
