Made at Saitama or Solon?


Edit: My mistake, not Solon, but Mentor!

The lamp is definitely from Saitama, Japan.

These lamps also could be made anywhere else except Japan?

Yes, Iwasaki has other HID lamp factories, such as in Solon, OH, USA (the one referred to by Globe Collector).

They have quite a few other plants around Japan, although many have now closed. Each one did a specific lamp family...

one for Low Voltage Halogen, One for CFLi etc.


Now they have spread them about, so there is one is DaiLan, (China), and possibly Bien-Hoa, (Viet Nam) and I think there is another in somewhere in Taiwan. Keeping track of where they all are, when they open and when they close is important for us collectors, because it is one of the more important pieces of information we should know about our lamps in our collections...where they are from and when, because these two things are the primary determinants of the character of a lamp.

The third and fourth most important determinants of the character of a lamp is the engineering team that designed the lamp and the company who employed them to do so.


So if you see a Halogen photocopier fuser lamp with a date of 1995 and bearing the Iwasaki/Eye Lighting brand, pretty good chance it is NOT from Saitama, but rather Minamuomuma.

Oh, I was wrong about Solon, that is Venture Lighting, Iwasaki is nearby at Mentor, the two are quite geographically close and quite close to Nela Park as well, all are in the East Cleveland area. Lamp makers often site close to each other...look at SELZ and SPO in Seransk.

So far I have no example of any Mentor product is my collection because thay are quite difficult to procure outside of the United States and Canada.

Here is the Mentor plant, it is quite small, particularly when compared to Saitama....I reckon they just assemble H.I.D. lamps there from parts shipped from Saitama. So, really only the outer bulbs.....It must be less costly to ship small parts like arc tubes from Japan to the U.S. rather than the more voluminous completed lamps.

It is easily done Max, as there is an almost infinite number of incorrect ways, but only one, or a few correct ways!

I agree that this one is from Saitama in Japan. It is a relatively early construction, containing a ceramic heater in series with a glowbottle starter. These were produced in the 1990s after the original version with tungsten ballast, and before the present construction with FEC ignitor. The inside etch also makes it a pretty early lamp, and at that time Iwasaki did not yet have an HPS factory outside Japan.

I have some with the tungsten filament mounted just above the neck and some with the FEC (Ferro-Electric Capacitor) starters. I'd have to get to the collection to check to see if I have any of this design.

My representation of Iwasaki products is rather poor as the agents for their company here in Australia were a bunch of ratbags.

Was it hard to get free samples of those nice Iwasaki lamps, Andrew? Were those Japanese lamps common in the Australian market?

Max, Iwasaki were in the Australian market, however Australians are a "bunch ignorant plebs" when it comes to things like lamps. As the quality of the Saitama products was so high,so was the price...so they were only ever purchased by the few who could recognize the quality and see the benifits that came from it.

I would say, just as a really rough guess that Iwasaki held about 10-15% of the lighting market here.

The Iwasaki agents there were absolute a-holes when it came to giving samples for future preservation this is why their representation in my collection is so poor.



The local Iwasaki agent here in Hobart was "tight as a fishes a-hole" so I went up to Brisbane where the national agent was located....they were even ruder and told me to "get lost" (despite how far I had traveled) ...that was back in around 2004. I just ewish I had the chance to go directly to Saitama, I reckon I would have been treated well there.

I worked for EYE Iwasaki in Brisbane for 7 months in 2002 and yes I can confirm they are a bunch of [name removed]. One of the sons of Mr. Iwasaki himself was working there at the time to train him up for the family empire and he was quite nice though.
