Had a friend who was getting rid of his unusual HID lamps, and he did't want to pay for disposal, so he gave them to me. This was in a box of many, and a box of many other boxes. I went to a second hand store to buy another an old file cabinet to store them (first one is stuffed with CFLs, CFL and fluorescent ballasts, photocells and related gear). It has four drawers which are 4'x 2.5' stuffed with lamps...sometime its hard to close the drawers.

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

Envy, envy, wish someone would give me boxes full of old and rare lamps

My friend only sold lighting for a living. It wasn't a hobby to him, like it is to us. But I guess that works in my favor.

My friend who ran a lighting shop only ever dealt with LED, so no use in that respect, although I did get a couple of MH lamps he found in the shop.

Iwasaki have white HPS lamps "Specialux", which can operates on standard HPS gear. I don't know if this lamp is one of these.

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.

Awesome lamp. I have a 250w EYE Specialux lamp. You can operate yours off any 400w S51 HPS ballast. Be patient as Specialux lamps can take a while to warm up.

May all the great lighting technologies have their place in history.

This is a super high pressure sodium lamp...the spectrum shows a REALLY WIDE resonance inversion and has a CIE co-ordinate very much nearer the black body locus than and ordinary high pressure sodium lamp so it looks like tungsten light. ANY type of super high pressure sodium lamp is rare! Iwasaki and other Japanese manufacturers make some INCREDIBLE H.I.D. lamps...but many never leave Japan.

I have a few black body sodiums...but none like this.

Just a filing cabinet.....hells bells, I'm up to two 20' shipping containers and counting!

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

This is the only spectrum , I've done of a white HPS lamp (Philips SDW-T). I think that the Iwasaki lamps, burns with a similar resonance inversion, as the lamp that produces the spectrum I captured in the following link, is of a Philips SDW-T that burned at 3000-3500K, and had a whiter light than a halogen lamp.

But if you ever have to move...

If I still had my original collection, we'd probably be running neck and neck.

I HAVE just moved! My lamps used to be on the same block now they are 35Km, (21 miles) away form the location shown and 25Km from where I live now. The green container near the fence is jammed full of lamps, the other container had no lamps in it at that time. Since then I have moved the main collection into a newer Hi-Cube container and the old green container has duplicates and packaging etc. in it.

Do you have the datasheet for this lamp?

Does it cite a value of running arc current?

If so, then you can run this lamp using the principles of this circuit.

Just updated the data...this lamp runs at 2500K, has a CRI of 85, and only produces 50 LPW...that's less than an equivalent wattage mercury vapor lamp, and only a 9,000 HR service life! I'm sure these lamps were not cheap when new. (The added data comes from the 2002 EYE lamp catalog.)
