Can I Really Save on My Electricity Cost by Installing New Lighting?

We have all been told that fluorescent lighting uses less electricity than the old incandescent lighting, but will it really make a difference to my building’s electricity bill if I change out all that old lighting. The answer is yes! Replacing old inefficient lighting with new efficient lighting is the most cost effective way to save money on electricity.

Let’s take a look at a couple of options for lighting saving energy costs in the common areas of a typical condominium building:

  • Convert from T12 to T8 Fluorescent Tubes – Most buildings had T12 fluorescent tubes installed in the parking areas and hall ways when they were built. Each T12 fluorescent tube consumes 40 Watts of electricity and needs to be replaced after about 2 years of use. Many buildings have already converted to newer T8 fluorescent which typically consume 32 Watts of electricity and need to be replaced less frequently than the older T12 tubes. If your building has not yet made the conversion to the newer T8 tubes, now is a good time, because the Ontario Power Authority (OPA) Save On Energy incentive program will pay for 100% of the new lamp and electronic ballast transformer cost. The table below shows the savings for a garage or common area with 125 T12 lamps.

Benefit to Convert From T12 to T8

Fluorescent Lighting

T12 Annual Energy Cost

$4,710

T8 Annual Energy Cost

$3,768

Annual Energy Savings (T12 Cost – T8 Cost)

   $942

Incentive for T8 Lamps & Ballasts

$1,550

Cost of T8 Lamps, Ballasts & Installation

$3,200

Net Cost (Cost – Incentive)

$1,650

Payback

21 months

             As you can see, the annual energy savings would be $942 and, with the incentive, the payback would be in 21 months.

  • Convert from T12 to Light Emitting Diode (LED) Tubes – This lighting energy saving option looks at the conversion from T12 fluorescent tubes to LED lamps that are the same size as the T12 tubes and will fit in the same lighting fixtures. While the T12 fluorescent tubes consume 40 Watts of electricity and need to be replaced after about 2 years of use, the LED lamps typically consume 14.5 Watts and last more than twice as long as the fluorescent tubes. The good news is, the incentive program that will pay for 100% of the new T8 lamp material costs is also available for converting to LED lighting. The table below shows the savings for a garage or common area with 125 T12 lamps.

As you can see, the annual energy savings would be $3,003 and, with the incentive, the payback would be in only 7 months.
