Cost comparison of 250 watt sodium light and 90 watt LED light
High pressure sodium lamp 250 watt bulb.
0.275 (Billable Wattage) x 4166 burn hours (average per annum for a street light) = 1145.65 units per annum
1145.65 x 0.1094 (ESB unit cost) = €125.33 plus VAT @ 13.5% = €142.25 per Street light with a 250 Watt bulb.
90 watt LED bulb.
0.116 (Billable Wattage) x 4166 burn hours (average per annum for a street light) = 483.256 units per annum
