Some HPS, especially those that are old and well used up can look like that during start-up for 30-45 seconds and then gradually get orange.  Some HPS lamps at that age may never make it to full operating temp and thus look like a MV instead.  That being said, this looks like a MV to me.

The more you hate the LED movement, the stronger it becomes.

I don't disapprove of LED's for domestic and other indoor use, I just don't like them for street lighting.

I"m don't speak english well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I hope that LED won't replace all forms of other light
