I came across a box of Westinghouse Lifeguard Mercury Lamps - 175 Watt - H39KC DLX WHT.
They are NOS (New Old Stock) - Bulbs were found in a storeroom and appear to have been there for years!
They were manufactured in April of 1976.
The inner Arc Tube looks fine (to me) and shows no discoloration.

If anyone would like to buy to throw out an offer (incl shipping) here - I'm open - Just send a Private Message.
Shipping from Virginia Beach, VA 23456

I can accept Venmo or Paypal (prefer Venmo as there are no fees).

Note: I don't have any way of testing these as I don't have a fixture that I could test them in.
Also, these were in a storage shed and the cardboard, due to age, is not in the best shape - if you are interested in these for their packaging, the collar cardboard wrappers around the neck () are brittle.

For those international buyers...I know that some of you have lighting friends here in the States that you have coordinated with in the past - please work with them if you would like to make a purchase.  I'm not familiar with the postal regulations of shipping internationally but I'll work with anyone who wants to work with me!

I am definitely interested!  I put it in my watch list.

I think I know who is gonna buy one. His diseases has taken over his wallet!

If "he", who self-described as having some sort of addiction to the words Westinghouse & LifeGuard, is "who" you're thinking of,  "he" may have already bought two!   

I am definitely interested!  I put it in my watch list.

I only have three left (only two are listed on eBay).
You should be safe...it seems as though the immediate interest already died down from those who wanted one.
