Costs

Here are some typical costs from Home Hardware. Prices are in Canadian Dollars. To my surprise, the large differential between fluorescent and LED has dropped to 0. The price of fluorescents has risen and the price of LEDs (Light-Emitting Diodes) has fallen.

40 watt halogen $3.70
13 watt fluorescent (40 watt incandescent equivalent) $7.14
