Guelph Council Chambers was retrofitted with new light emitting diode (LED) lighting to replace burned out and faded light bulbs.
The new LED lighting will save about 8,500 kilowatt hours (kWh) annually — roughly the amount of energy used by one household over three months, which reduces our energy costs by about $1,250 per year. An additional $5,000 will also be saved annually in maintenance costs, based on 2,000 hours of operation.
The retrofit replaced 91 incandescent bulbs and 136 fluorescent lamps over three days and cost $19,870.
Facts about LEDs

- produce less waste heat and that means less energy is needed to cool Council Chambers
- improve light quality: they’re brighter and don’t fade as much over time
