Requirements:

• To produce energy and cost savings at luminaires with magnetic ballasts whilst retaining the existing fittings.
• To give an improvement in the standard of received light by lamp upgrade.
• To achieve a reduction in maintenance costs by longer life of tubes and removal of the need to use starters or chokes.

1. Replacing the magnetic ballast with High Frequency Electronic Control Gear (HFECG) which will produce a typical 25%+ load saving.
2. Separate starters are not required with HFECG units.
3. Replacing the existing Halo-phosphate tubes which have a useful life of 8,000 hours with T8 Tri-phosphor lamps with a life of 18,000 hours.
4. There is far less degradation of light standard throughout the active life of a Tri-phosphor tube.
5. The flicker usually associated with magnetic ballasts with starters is eliminated.

1. A detailed survey is always carried out to establish the number of luminaires to be upgraded.
2. The tube length and the number of lamps in each fitting are noted.
3. A full survey report is prepared using daily usage hours, days used per annum and electricity cost as supplied by the client. The report details the current load and costs as well as the new load and anticipated energy costs after upgrade.
4. The survey report also details: -

• Cost reductions – usage and maintenance
• Energy reductions as kWh’s, GJ’s, kg CO² and kg Carbon.

The report is prepared at no cost to the potential customer or obligation for the client to proceed with the upgrade.
