My first /N! This lamp came from eBay, the seller probably had a case of them, man they sold like hotcakes! I've been pretty lucky to catch one!

The colour is somewhat close to that of an incandescent lamp, but especially very similar to a soft white CFL. I lit a CFL next to it and there was no difference!

Now I need a USED /N!

Yes, these are hard to find, I picked it in the thumbnail from its slightly yellow colour. I got a 400W one from a shopping centre near me, but I had to swap about five /DX's to encourage him to get it down!
I have some lower wattage ones somewhere, either 175 or 250w and I have about four of them, all are new in original packets.

Manufactured articles should be made to be used, not made to be sold!

I have a few Sylvania /N lamps but in the 100 watt size.
