Westinghouse Ceramalux/4, C250S50/DX4, deluxe High pressure sodium lamp.

"The indoor light with outdoor economy."
"The outdoor light with indoor color."

There’s virtually no data available for this lamp, but what follows is what little is available: Around 1978 or 1979, Westinghouse created and brought this lamp to market. (General Electric followed suit about two years later with their own version.) This lamp was the first deluxe high pressure sodium lamp. It appears that it was discontinued sometime after the Philips take over in 1983. It also appears that this lamp was not a great seller. (Philips around 1990 reintroduced the DX lamp and called it by the “Comfort” branding.) Originally only sold in the 250-watt version, a 150-watt (100V/S66), and a 200-watt (S66) version were added later.

Suggested retail price is $71.00, in 1980 dollars.

Good question...I've wondered that myself.

Your mission - should you choose to except it - is to save unique and rare HID lighting before it's all scrapped.

Nice lamp! I was not aware that Westinghouse used its infamous wire seal construction for its deluxe HPS lamps as well. It's no wonder that Philips phased it out when the Dutch took over Westinghouse's lamp portfolio. BTW I have the original version of this Ceramalux/4 with niobium end caps, I will dig its photo out of my archives and post it here.


I wonder what the "4" represented.

In the early days of HPS technology, both Westinghouse and Sylvania added a number after "Ceramalux" and "Lumalux" for some lamps. I also wondered what that meant and the only conclusion I could draw is that those numbers referred to some product generation or lamp type. This practice was abandoned at the end of the 1970s.

I had no idea the deluxe HPS/"comfort" lamps were made that early and by Westinghouse no less. With that price no doubt it didn't sell well. Very unique and rare find! The Philips Ceramalux Comfort lamps are still rare & expensive. I assume Sylvania never made a deluxe HPS or white HPS lamp...at least I've never come across one in their catalogs.

I'm lampin...

That price adjusted for inflation would today be $216.37(!)...that's a pretty steep price for a 10,000 hour lamp.

Here's the original Ceramalux-4 with the cap-sealed burner. By the way, the light color temperature is 2400 K, not 2200 K (Westinghouse's data published in "Lighting, Design + Application" 1980).

Nice!
So this one runs on the same gear as a basic HPS lamp of the same wattage?

Yes, this lamp was designed with an 100 V arc voltage so as to be fully compatible with existing 250 W HPS lamp systems.
