NIB Goodwill find for $1. It's a similar design to the Philips 3-U lamp, but this has a thinner T3 tube and one of the U's doesn't go all the way down due to having its cold spot nipple at that point. This nice little lamp has a very yellow colour and is programmed-start.
Another unusual thing about this lamp is it has a long afterglow after being turned off....it glows faintly, but noticeably orange for more than a few seconds.
I have a "Keystone" 22w circline lamp that does that! It's a weird color temp too, between 3500K and 4100K I'd say. Much brighter than a halophosphate warm or cool white, or daylight deluxe lamp, too.
