My BT-25 collection!!!
Here you see are my whole BT-25 collection!

The top row is all HPS lamps.

The middle row are used mercury vapor but actually works (some may need start up aid)

The bottom row are NOS Mercury vapor lamps! 

Can you guess brand and the circa age of each? ;-)

Hi Jace they are Cool they are super rare in the UK, as we don't have 100w Mercurys, out of Interest I have a Sylvania clearbander, a Sylvania cleartopper, 2 x Westy clear Bulbs and 2 xWesty Coated Bulbs, I also have 2 x Philips 70w and a Sylvania 100w HPS, with Clear Bulbs.

All the Best

are the two mid 80s Philips HPS lamps 50W because I bought 2 two 1987 Philips 50W HPS lamps from ebay
GullWhiz   [Apr 03, 2011 at 05:48 PM]
One is a Mid 80s Philips HPS coated....the others I believe are pure Westinghouse branded from 1984..in 70 watt
