Click to view full size image

This is a type of home sunlamp popular in the 60's & 70's before sunbeds with tubes became available. The lamp is a Philips MLU300 mercury blended type with a 125W high pressure arc tube, ballasted with a tungsten filament which provides additional heat. It was also promoted for other health uses, the instruction booklet says "To be used only when prescribed by a doctor" (!!)

The lamp transmits UV down to 300nm and infrared up to around 3000nm.

Yes, to promote Vitamin D production amongst other things. It was also used for tanning, before sunbeds with tubes became popular.

I don't disapprove of LED's for domestic and other indoor use, I just don't like them for street lighting.

These were REALLY EXPENSIVE in the 60's...I remember that my parents wanted one, but could not afford it. Many of our family friends back then...one who was a Jeweler and another who was an Electrical Engineer had one!

We had the Red front I.R. model and my father mounted it inside an old car headlight body as we could not afford the luminaire. He also had to modify the B22d-2 socket to B22d-3.

I've since found another one, with a lamp dated 1966 (it has the newer letter/number 2-character code, so was a lot easier to date..!) Didn't really need another complete fitting, but I wanted a spare MLU300 lamp and this one came with the original purchase documents, which show it was sold in 1968..!

The Infraphil IR ones are very common as well, I have a spare lamp already for that one, though.

Both this and the Infraphil entered the domestic environment and were very little used, (I challenge ANY collector to find a really hammered MLU or Infraphil) and they were not really NEEDED objects anyhow, just fads fueled by marketing hype and as such the fad faded and they became avalable en-masse.

As I mentioned somewhere here, we did have a bank of six MLU's to develop PCB's under, back in the days when Aussies actually did something besides sitting on their bums in offices!

You're probably right, I doubt any of them were heavily used. Was it the same type of MLU lamp with the 3-pin cap you used for PCB's..? James's page on them mentions a screw-capped version being made for that purpose.

I have never seen any E27 version or the four pin version James mentions...the ones we used were simply the common B22d-3 versions. From an efficiency/efficacy standpoint we probably should have used HPR's but they were prohibitively expensive and the MLU's..although still expensive, were less so than HPR's.

In later years TL XXw/05's were more commonly seen as these were FAR cheaper than either HPR's or MLU's. Now, however, MLU's are as cheap as chips and I see one about every six months out and about. I have so many MLU's now that I only really look for "special" ones now...i.e. Old date codes, unplated brass bases, round etch badges etc.

I have also picked up a few Osram Ultra Vitaluxes, these do have E27 bases.
