There is a pretty significant cost/time savings with LED (big shocker).
For the town I live (I'm on the budget committee so we get this information), a monthly sodium bulb costs about $5 worth of electricity. An LED about $1.5. Also, sodium bulbs need to be replaced every 3 years or so while the LED bulbs are projected to last around 14-15 years.
For base cost, I'm not sure of the sodium module but the LED modules with bulbs cost around $500.
