It’s commonly known that LED luminaires are expensive. They cost at least 3-4 times more than T5 fluorescent lights. However their life is also much longer as compared to fluorescent lights.
LED lights are super energy efficient, using approximately 85% less energy than halogen or incandescent lighting – meaning significant savings on your power bills. LED lights also have a much longer lifespan than other types of lighting - see the table below.
|T-8 LED Tubelight||Rs 1600-2000||3-4 years||10-15 years||About 110-120 lumens per watt|
|T-5 Fluorescent Tubelight||Rs 500||6 months to 1 year||3-4 years||110 lumens per watt|
|Regular Fluorescent T-8 Tubelight||Rs 100||3-4 years||60-80 lumens per watt (lower for one with electromagnetic ballast)|
The table above is based on our research of costs of various types of tubelights. The LEDs are expensive but they last long and thus provide energy saving for longer periods. Their payback period (or cost recovery due to savings in electricity bills) is slightly longer just because of the upfront capital costs. Please note that the payback here is in comparison to regular T-8 lights.
