GE or Norelco /WDX,  or Sylvania /N, or Westinghouse /N preferred.

Have a look at these medium Sylvania 100 watters:  https://www.ebay.com/itm/185336524515. Ryan (HPSM250R2) is selling two cases and can't sell the lamps individually.

Now go here https://www.lighting-gallery.net/index.php?topic=13090.0 add a reply that you want a few. Someone WILL buy a case. The problem is shipping to me is: $28.57 International Priority Shipping to Canada. What's it to you?

Shipping to me would be $18.30 according to eBay; The seller is away until April 27th.

Now he has them at 59.99 plus 18.30 it would be near $5.25USD per lamp if shipped to you first. If you keep a few, are you able to ship the rest to Canada & the UK?
