Compering Regular LED Tubes vs GLL LED Tubes -Power Consumption Data

58 Marine Parade Dr., Toronto


The underground parking garage of 58 Marine Parade Drive is operating with light fixtures of one 4-foot T8 14W LED tube (Type A) on all parking spots and they are operating 24/7, 365 days a year. On April 19th, 2021, one 4-foot GLL T8 LED tube with built-in motion sensor was installed as a sample and two power meters were installed to show the different electricity consumptions between the existing 14W LED tube (Type A) and GLL LED tube with built-in motion sensor. After the 42-day examination, the existing 14W LED tube (Type A) consumed 20.31 kWh electricity in total. While GLL LED tubes with built-in motion sensor consumed only 4.87 kWh electricity in total. Therefore, 76.02% of electricity consumption saving is achieved.
