2.Polor-Lites H62-70-HPS 70 watt high pressure sodium vapor lamp

3.Regent H-39-KF175-R 175 watt Clear mercury vapor lamp

4.General Electric H-39-KC-175/DX 175 watt delux white mercury vapor lamp

Gee Whiz.....I got way too much to list them......... those and MORE

All the HID lamps in my collection are shown in my HID lamp album.If I have more than one type of lamp, only one is shown.

Yup same as Jace I have too many to list !

ok,new rule.

if you have less than 10 hid lamps you may list all of them.

if you have more than 10 only list your absolute favorite ones.

I am not much of a HID collector as I concentrate on fluorescent lamps, however over the years I have built up a small HID collection of 7 lamps:

1. 1980s Wotan 'UltraVitalux' Blended MV 300w*

2. 2001 GE Lucalox 70w HPS (Coated, internal starter (I))   
3. 2001 Osram Vialox SON-E(I) 70w

4. 2003 TRAC 80w C/C Mercury Lamp (MBF)
5. 2004 BLV 70w Coated MH 4000k
6. 2005 Osram Vialox SON-T(E) 70w
7. 2007 Osram Powerstar 70w MH 4000k (Double ended tubular, clear)

*Lamp #1 got SMASHED in late 2000 but the arc tube survived and remains in my collection.

The rest of the lamps are all in very good condition, and will probably remain that way as I no longer use HID lamps on a regular basis. I might get them out once in a while although since my SIP ignitor has broken I can only use the MBF and self-starting HPS lamps!

Too many to list! But among the ones I have include a few Westinghouse E-H1 400w mercs from the 50s, some GE, Sylvania and Westinghouse mercs from the 60s and 70s, a couple 40s medium pressure mercs, etc etc.

do you have any absolute favorite ones?

My HID collection is growing sloooowly, so a pretty small collection, unlike someone that posted just before me... LOL   So in order of acquisition:

1. -1st ever- Caster 175W mercury lamp, still going strong today.
2. EYE 125W mercury lamp, works, but much too dim.
3. Sylvania 175W mercury lamp, still working too.
4. Sylvania 250W high pressure sodium lamp, bought in clearance, recently tested and working fine.
5. Philips 175W mercury lamp, found broken, one of the contacts broke at the base, so only good for scrapyard.
6. -E26 base- Sylvania 150W HPS lamp, working.
7. Philips 150W HPS lamp, got it with my streetlight.
