Poll: Color Choice for Street Lighting

1. Sodium vapor lamp
2. Mercury vapor lamp
3. Other - please specify

While most street lighting (atleast in Chennai) is by sodium vapor lamps one still finds streets lit by mercury vapor lamps. Which one is better in your opinion for visibility in the night?

There may be other reasons for using one over the other: initial cost, running cost (read power consumption), maintenance, longevity etc. Please do not consider these parameters for the purpose of this poll.
