LED streetlights are easy to modify to color them, but it would be cool to see a street lit with colored metal hailde or even better mercury vapor lamps. Smiley

To anybody who lives around Chicago, if youre ever driving on I90 at night (around the Elgin and West Dundee area) there are a few large office buildings (all are same company) with large 1000w MH floods uplighting the building, The center building uses standard white lamps, but the other two buildings to the right and left use blue and pink/magenta lamps, it looks pretty cool

Not sure how you'd get different colours out of an MV..? I know you can modify LED's but they're just glare bombs, they just don't look the same as proper lamps  Sad

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

You change the phosphor to get colors from a mercury vapor lamp.

I've no doubt, it's just that I've never seen them in use or for sale as with MH lamps.

They are not made, but would be just like colored fluorescent except more red phosphor to compensate for the blue-green arc tube light.
