5HO tag « on: June 12, 2009, 04:33:58 AM » Author: bluelights
On some smaller streets we have streetlights with a "5HO" tag, on a green background. They are HPS of course. What does that mean?

The future of street lighting is Induction, not nasty HPS lights or cr@ppy LED lights!
Preheat CFL's should make a comeback!
