Was this one acquired off of eBay? Anyway, nice collector lamp. (Did the razor blade come pre-installed in the lamp? )

It does look like it's stuck in the side of the arc-tube ! Doesn't it ?

I am pleased to see another collector bought this one, it was on sale for ages and I thought there would have been more interest in such an early HPS! They are so rare to find with the BU / BD arc tube and full metal end seals.

Thanks, i stumbled upon this lamp by accident while looking at the seller's other lighting items. I actually went by it and then thought "wait a minute" and went back and looked closer! I'm Glad I did !

My very first HPS lamp, acquired back in 1976 was the next model after this....same packet, slightly different arc tube seals.

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

As James says, these early Lucaloxes are historically significant lamps. I agree, getting a 1960's HPS is an uphill battle these days.

My first HPS that I had when I was a child, I think the bulb design is beautiful and the way that GE builds the frame with the dimple supporting it is really cool, it reminds me very well of an MV. The last time I saw a GE hid lamp, it was a box with 44 CMH of 150w that are currently installed in a square with Ilumatic luminaires with ballasts from Intral.

And also very durable, mine was also 400w, but with an aluminum base, the lamp only started cycling at 15 years old.

I used a ballast from the Brazilian brand Tecnowatt, excellent too.

@Choukai Kai: This is one of the very first lucalox lamps to include an external amalgam reservior. They were made separately for base up and base down, since GE has yet to find a solution to use the external amalgam reservior in an universal burning lamp.
I think you have the lamp for the European market, which was made at the 90's, after GE brought Tungsram.

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.

Exactly, it was from the 90s, including in Brazil the base is of European standard GES "E-40". It was common to see them in open fixtures of old 250w mercury vapor, as the ballast is external, this modification was more practical.

I noticed that the Lucalox with external ballast are more durable than the current Vialox with internal ballast, which was to last 4 to 10 years, nowadays it is only 2 to 3 years.
