Here the lead lighting specializing in LED solutions including interior and exterior LED light including LED tube light and LED bulb analysis of intensity distribution of LED tube light and LED bulb with the traditional energy saving light and make an actual test for us to see how bright LED tube light and LED bulb is in the end
An ambient temperature : 28 degrees Humidity : 60%
Test results are as follows :
1.A traditional energy-saving lamps : average intensity : 60.40cd average intensity per watt : 60.40cd/16.81w ( actual measured ) = 3.59cd / w
2.LED tube light and LED bulb : average intensity : 52.47cd per watt average intensity : 52.47cd/2.69w ( actual measured ) = 19.50cd / w
comparative analysis of LED tube light and LED bulb with energy saving lamp :
LED tube light and LED bulb / energy saving lamp : 19.50cd/w/3.59cd/w = 5.4 times, that the power consumption of LED tube light and LED bulb is 5/27 that of energy saving lamp, energy-saving rate is 82%.
First, test conditions
Time: evening after dark ( to ensure that no interference of other source)
Location: a laboratory company
Testing equipment : light meter ,the probe is 1 meter away from the lamp .
Second, the test fixture :
13W energy saving lamp , 3.4W LED bulb or LED tube light , 5W LED Bulb or LED tubes , 1.8W LED bulb or LED tube.
From the above comparison test , we can see
The brightness of 1.8W LED bulb or LED tube light is equivalent to that of ordinary 25W incandescent bulbs ; under the same illumination , the power consumption of ordinary light bulb is about 13 time more than that of LED bulb or LED tube ;
The brightness of 3.4W LED bulb or LED tube light is equivalent with that of 13W energy saving lamp, under the same illumination , the power consumption of energy saving lamp is 3.8 times more than that of LED bulb or LED tube light .
