400W High Pressure Sodium Grow Lamp for Decorative Orange Lighting

I try out a HPS grow lamp to light up some large trees using a cheap second hand ballast.

Kind of expensive "decoration"...

Only about $60 worth in total. I would call that cheap.

@@michael2305 Are you saying around 15c per hour is expensive to run it? It lights up about half an acre so not that small a glow. I drink about 40 times that per hour in beer or wine while looking at it.
