Case Study for FMV Project


With the advent of LED solid lighting technology coming into the residential and commercial market, smart building owners and property managers are gradually retrofitting their common area fluorescent lighting system with LED lighting for the simple economic and environmental goal of reducing whole building electricity consumption, operating cost and at the same time shrinking their environmental foot print. Other advantages of the LED lighting retrofit proposal include much longer life expectancy of the new LED light compared to existing fluorescent tubes. A typical LED tube is more than triple the lifespan of the fluorescent lamps, therefore further savings on operating and maintenance cost in the long run. Current fluorescent lamp technology contains small amount of mercy whereas LED tubes are environmental friendly and contains no mercury or any hazardous materials at the end of their life.

Introducing GLL LED Tube with Sensor

Globe LED Lighting (GLL) LED tube with sensor is the latest inventive breakthrough in the commercial lighting market and specialized for underground parking garage, common hallway and stairwell. It can fulfill enough brightness for people who walk there and drivers to park the car safely. It changes to eco mode (3W, 6W or 9W) automatically when there is no vehicle or human movement, the eco mode still provides enough brightness or minimum lumens for monitoring purpose and meeting all municipal code requirements. The electricity consumption of this LED tube with sensor is only 19% of the T8 fluorescent lamp. It will achieve the ultimate goal for “saves energy while provide the enough brightness.”  It will solve energy wasting problem for underground parking garage light, common hallway light and stairwell light. The regular LED tube’s lifespan is around 50,000 hours. The GLL LED tube with sensor has longer lifespan than the regular LED tube due to the sensor let the LED tube works under low power condition most of the times.

Introducing Repairable GLL LED Tube

Another unique feature of GLL LED tube with sensor is that it is repairable. The 70% of the LED tube cost is for the LED chips, they usually have a very long lifespan. However, the electronic adapter of tube is the part where the most of the problems occur, but the cost is very affordable. GLL LED tube’s modularization is designed to give its advantage of simple repairing process, and it decreased the cost for repair rather than replacing the tube completely, it also decreased the wastage.
The sensor parts (please see P1).  The adapter parts (please see P3).
The adapter and sensor parts are connected to LED chips with plug.



The latest inventive design of GLL LED tubes with sensor made it great for application like underground parking lot, stairwell and corridor. The following saving can be achieved if FMV replace all the T12 8’ fluorescent lamps in underground parking lot to GLL LED tubes.


A. The annual energy savings: 1,037,640.98KWH
B. The annual economical savings: $141,368.32
C. The project cost:  $212,104.35
D. Incentives: $41,127.5(Ontario)
E. The payback period: 1 year and 2 months


2. Background


First Markham Village (FMV) is a townhouse complex located at 8 Cox Blvd, Markham ON L3R 4G1, near HWY 7E and Warden Avenue. FMV has a big underground parking lot which has a capacity for 800 cars. There are 895pcs of 110w T12 8’ fluorescent lamp and 284pcs of 60w T12 4’ fluorescent lamp. The lighting system is an old system that consumes a huge amount of energy, and the voltage of lighting system is 347V.

The Map of Underground Parking Lot at FMV

Globe LED Lighting Inc.(GLL) has installed 2 portable power meters at parking stall #85 and #87 on Dec 16, 2013 to track the electricity consumption of two T8 4’ LED tubes with sensor and one 110wT12 8’ fluorescent lamp.
