Speaking of...We got together today for a meet. Drove around looking at some other light scenery, including in his old neighborhood he grew up in: An old mobile home park, but many things haven't changed since the late '90s...same lights still there, lots of old mercury NEMAs!
We did exchange lamps, I gave him some goodies, and he gave me some real gems.
-Sylvania GTE H39KC175/DX from '92, low hours.
-Sylvania GTE H39KC/DX clearbander from '78, also low hours
-Westinghouse 'Lifeguard' H39KC175/DX, fully coated but thin coating, has some hours but still bright...'76 I think.
-GE Bonusline 175w /W. Don't know the year, will have to ask. It's an ED28. Never even seen a /W until this, a real beauty! Really interesting color, I need to try it next to a Feit Diffused lamp, seems close. Definitely not like /DX!
-Sylvania 150w Unalux retro lamp for 175w HX mercury ballasts. Neon filling I think. MAN that sucker is bright AF.
-And a Cooper/Regent 175w yardblaster which came all the way from Michigan. Ballast is a little raspy/loud. I need to pick Keif's brain about transformer-varnishing the ballast.
I'm going to give him back a '98 Sylvania BT28 /DX he gave me some time back, since between lamps he's given me and others I have more 175s, especially /DX, than I will probably ever burn through.
