i took pics today and will post tomorrowor wednesday. he also sent two NOS Sylvania F14/D lamps from the mid 2000s some time. for the F40s, daylight is a little too blue for me but for the F14s, i LOVE the daylight color!
the light is preheat and hardmounted to a shelf over my bed (yes, i'd be screwed if there was ever an earthquake and the shelf fell on top of me lol but the worst we've ever gotton was just enough to make the china cabinet rumble and shake your glass of water a little)
I was debating whether to use a Westinghouse /CW, and ITT /CW, a 2005 Sylvania-made GE /CW, or one of the daylight F14s that Darren sent me but i settled on a Westie F14/CW. Even though the ITT and Westie lamps are both /CW, the Westie has quite the yellow tinge to it. I don't really mind though.
the lamp is brighter with the choke though. funny thing is, on one of those 14/15/20W ballasts, the lamps all give off the same amount of lumens so the F14 is very bright and gives off as much light as a F20 and the F20s look underdriven lol.
