Usually it uses T8 fluorescent tube for the underground garage lighting. This kind of light source need to use 8W magnetic ballast and its totally actual power consumption is 44W. It not only consumes a large amount of electricity, but also there is humming noise and stroboscopic. So that it needs to replace the tube and the starter frequently . That means it is very tedious for maintenance.

It has been adopted by many developers and property management companies to use LED fluorescent lamp (without induction/ with induction) to replace the ordinary T8 fluorescent lamp. It is not only the most rapid and effective project for lighting energy saving reconstruction, but also an important measure to promote the national energy saving.

The luminance of 12W T8 LED fluorescent lamp is the same as the luminance of 12W T8 fluorescent lamp. But the power factor is more than 0.9 with small loss. Compared with T8 fluorescent lamp, it can save 90% electricity. And there are many characteristics, such as no mercury, no ultraviolet radiation, wide input voltage range, no noise and no stroboscopic. It is the frist choice of energy saving light source for the energy-saving renovation project. It is suitable for the place which needs 24 hours lighting.

When there are vehicles and people around, T8 LED infrared sensor intelligent control fluorescent lamp will provide adequate lighting luminance. And when vehicles and people go away, it will turn to the lighting condition of 20% luminance. So that it can be more energy saving and environmental protection.

Return on investment saving reconstruction

If the underground garage is an area of 10000 square meters . And there are 600 lamps. And the working hours of a year is 4Hours*365 Days=8760Hours. And the electric charge is calculated as 1 yuan/ kilowatt hour. The cost of the workers to replace the tube is about 20 RMB/ PCS.

Comparison table

Energy saving calculation details

1. Annual electricity consumption spending

Annual electric chargespending = lamps quantity*wattage*annual working hours* electric charge

Fluorescent Tube: ( 600 *44*8760/1000) *1.0 = $231264

12W LED Tube: ( 600*12*8760/1000) *1.0 = $63072

18W LED Intelligent Induction Tube: ( 600*4*8760/1000) *1.0 = $21024

12W LED Tube can save the cost of $11 4318one year

18W LEDIntelligent Induction Tube can save the cost of $210240one year

2. Tube-replacing spending (As the working life of the fluorescent tube is not very long, it will be broken and need to be replaced within 3 years)

If you replace 30% of the fluorescent tubes, the replacing spending is as follows:

10RMB/ PCS *600PCS*30%=$1800, If the cost of labor is 10RMB/ PCS every time, so it will cost $3600 totally.

But the LED lamps do not need replace.

So that it can save $3600 for tube -replacing every year.

3. Ballast-replacing spending

If 10% of the ballast in the fluorescent lamps needs to been replaced within one year, the cost of replacing is as follows:

Actuator-replacing spending= (actuatorprice+ labor cost) * replacing times

Replacing times= (annual working time / actuator life) * quantity

So it will cost $ 20*600*10%=1200, If the cost of labor is 10 RMB/ PCS every time, so it will cost $4200 totally.

But the LED lamp do not need to pay this cost.

So that it can save $4200for ballast and actuator-replacing every year.

According to the table above : If you use the LED lamps , you can recoup the investment within half a year. The economic benefit is obvious. You can calculate the part reconstruction expense according to the proportion.
