That's interesting, I've never seen a PAR38 lamp like that, they usually have E26/27 caps, what is it intended for..?

PAR38 with Dual Side Prong base, is an American lamp format. I've seen this lamp format during the first decade of the 2000's in a lot of American lamp manufacturers websites, including Osram Sylvania and Philips North America. European lamp manufacturers indeed don't produces PAR38 lamps with Dual Side Prong base. Anyway, sealed beam lamps were much more popular in the US and Canada than elsewhere.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Cool Find, I have a similar Lamp but is a Later Philips brand with Medium Cap see HERE and for the same lamp lit see HERE

Re the Medium Side Prong PAR 38 Lamps, yes they are very common in the USA, also Thorn Lighting made a bigger PAR46 Lamp with Medium Side Prong cap and they were popular for Loco Lighting in Coal Mines, as they have Prongs there is less chance of sparking due to vibration where a Screw Type cap could work loose and cause sparking which could ignite Gasses (Firedamp) within the Mines.

Never knew a HPS lamp existed in a par format. Nice find.

Keep government out of the lighting industry.

I didn't noticed that this is a HPS lamp. I thought that this is an incandescent lamp.
All PAR38 lamps with medium side prong bases I've seen in websites of American lamp manufacturers, were incandescents.

Indeed. After reading Powergroove comment, I've read the text on the package and noticed Ceramalux, which is Westinghouse trademark of HPS lamps.

Yep...I've seen those pics. Same lamp except for name and socket.

Fair enough, but why not use B22d-3 caps..? I have a Philips Infraphil 150W lamp with a 3-pin cap.

I have personally seen magnetic ballast go more than 250000 hours and still work. Some would doubt me, some would say they are over engineered. I say that is a job well done. Nice score on those rare lamps.

I'm with you on that. I've seen excellent performance from ballasts made in the '70s, '80s, and '90s. I saw the build quality go down in the '00s. Now when I want a ballast, I look for NOS on eBay.

Very impressive to find one of these interesting lamps! There is a short note on their development in Kane & Sell’s book on the history of lamp engineering at the Westinghouse plants.

They were in fact developed for lighting of coal mines. Side prong incandescent lamps were one of the main light sources in American mines, using that type of base to avoid risk of arcing due to poor contacts. A special vibration-resistant mine lamp was made with a rough service filament but it still suffered short life due to shocks and vibrations, and was much less efficient than regular incandescents.

Westinghouse solved the problem with this HPS version which gave a tremendous boost in beam candlepower and life.

Another problem of the incandescents was that they projected too much heat onto the miners in an already very hot environment, so the coolbeam HPS reflector was developed and quickly became popular due to the more comfortable conditions.

In the 80s Philips offered an E26 screwbase version for general lighting but that never really became popular.
