There are two kinds of sodium lamps: low and high pressure. The low pressure ones have that very orange light. The high pressure ones have a much whiter but still orangey light.
I remember Telegraph Avenue in Berkeley in the 70's. It was lit with those low pressure sodium lamps. It gave everything an orange look, like it was all made of brick. I remember reading that the reason why law enforcement liked the lamps was because they didn't cast any shadows, so it was easier to spot people at night. I don't know if that's true, but it did seem like shadows were muted on that street. Perhaps something to do with the longer wavelengths of orange light.
I have a workshop that's about 25' x 50'. There are three banks of overhead fluorescent lights in there: 2 are comprised of five dual 8' long continuous fixtures. A third by a wall opposite the windows is comprised of five dual 4' long spaced fixtures. If they are all turned on at once they consume... 2*80*10 + 2*40*5 = 1,600 + 400 = 2,000 watts. That's a LOT of electricity. I can replace the 4' tubes with LED versions, which use less watts; Altos use 32 watts. LED versions use 14 watts. Obviously LED is the way to go. However the fixtures are old, and in some cases I must replace the ballast. Electronic ballasts also may use less energy than older inductive ballasts.
However the real problem is the 8' fixtures. Stock tubes use 75-80 watts each. When I looked a few years ago, I was not able to find any LED versions. I just did a google search and now there are multiple choices of 8' LED replacement bulbs, wattage from 36 to 45 watts. These require re-wiring the fixture to bypass the ballast (fine with me!).
For some reason the dual-pin 4 foot LED bulbs don't require ballast replacement. Go figure.
One problem I have is that on the property there's a substantial stash of new old stock of 8' tubes. Even though they use more energy, I'm a bit leery of abandoning them, and instead I figure I should use them up instead of going to the expense of upgrading the fixtures to LED. I might just upgrade some of the fixtures (the 8's are switched two or three per light switch). I don't recall seeing any 8' LED bulbs at the home improvement stores, though, but then I haven't looked for a year or more.
Usually I don't turn all the lights on in the shop at once. Just a bank or two as needed.
Later!
