Hi Wrenches;

I'm doing a small lighting project for the University of New Mexico. It 
will be a demonstration for future students, as well as a hands-on 
installation for my current class. We are proposing using Bollard type ( 
3 ft pedestal lights for along sidewalks, etc.). The only reasonably 
priced units are AC, and are High pressure Sodium. HPS lighting is as 
efficient or more so than fluorescents, but I'm concerned about  the 
inverter for HPS lighting. MY questions:
1) Do HP sodium light ballasts require pure sine wave?
2) How much surge capacity do their ballasts require to start (35 watt 
light), worst case scenario, ie.  very cold, very hot, etc.
3) Anybody have a good source for DC bollards maybe?

We found a site that had DC LED Bollards (wow!) but alas it was european 
and not available here.

Thanks for sharing your wealth of knowledge,

Ray Walters
