Westinghouse gumball with strange refractor
This is a string of 5-6 Westinghouse AK-10s, all except one have strange refractors such as the photo shown above. All are 100 watt mercury vapor, and are real nice to see at night. They are on a ramp leading from the old I-Street Bridge and runs next to I-5/CA-99 near downtown Sacramento.
The one with the correct gumball refractor. The I-5/CA-99 is visble in the background.
Here's one with a completely missing globe, showing a bare 100 watt ED-23 1/2 mercury lamp!
