These are really unusual and rarely ever seen outside Japan...the 6500K ones are particularly unusual...wonder what the chemistry is?

Dy,Ho,Tm,Tl,Cs Iodides like Osram I wonder?

We've just acquired a 6500K one, although it's pearl (internal frosted) rather than clear.

Although the lamp running voltage was 83V rather than 100V as quoted above when we measured it just now, so not sure why. The ballast is the correct type for this lamp, any ideas anyone..?

Max or James said somewhere in the site, that the chemistry is more complex than that of Osram, to achieve a Ra=96.

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.

The chemistry in this MT150D is quite simple, it consists of a dysprosium-neodymium iodide mixture complemented by a dose of cesium iodide. The trick which enables such a high CRI is a higher cold-spot temperature which results in a higher dysprosium iodide vapor pressure. In order to compensate for this salt's enhanced emission in the red, a bluish-white emitter is added in the form of neodymium iodide.

Thanks Max....another metal from the Lanthanide part of the table makes the move from "magnets" to lamps. Interesting that nobody else has tried neodymium. Also interesting that the high cold spot temperature (and hence vapor pressure) is required to shift the co-ordinates that last little subtle bit!

It is interesting how us humans can easily detect when CIE Co ordinates are just a bit off the locus!

I'm sure that neodymium iodide was tested by all major lamp manufacturers in the early days of the MH technology. It's only that other rare earth additives (i.e., Dy, Ho, Tm) were found to be easier of use, especially at lower cold-spot temperatures. Besides, a CRI of 85-90 Ra8 was considered as good enough, only Iwasaki pushed the daylight MH technology to its limits and thus needed an unusual fill chemistry.

Yes, the very high CRI seems part of the Japanese culture.

I have to get a few of these off Ratuken.

The Japanese are the inventors of the white HPS lamps.

The Japanese didn't invent the white sodium lamp, GE of USA did when experiments on high-pressure sodium discharges were done there in the early 1960s (K. Schmidt, 1963). The first commercial version of the technology was introduced in Japan though (Matsushita, mid-1970s).
