Sodium
This lighting system uses high pressure sodium light bulbs that emit red light. This creates a more intensive light than fluorescent lights which can be good if your plants need a lot of bright light, but it can also be a bad thing if your plants don't need that direct and bright light. Depending on the size of the light, it will cost from $50 to $250 or more (this is based off of larger lights, smaller lights range from $5-10).
The light shown in the picture costs about $118

Halogen
These lights don't put out as much light, but the light that they do put out is more natural. It is quite expensive to run for the little amount of light given off, but as previously said, it gives off a more natural light, which can be beneficial. The costs of the light bulb itself is quite low, ranging from $1.00 to $1.20. The cost of running the lights can be about $12.30 a light bulb per year, assuming it lasts between 1,000 to 2,000 hours.

Fluorescent
Fluorescent lights are lights that can be placed directly above plants (as shown in picture) or in a row higher above. This type of light is very energy efficient but can cost more than some of the other lights in its standard size. For a 15 watt bulb (equivalent to a 75 watt Halogen bulb) the cost would be between $4.00 to $10.00 per bulb, and it would cost less if you bought the bulbs in packs. The cost of running the lights can be about $2.30 a light bulb per year, assuming it lasts about 8,000 hours.
