Lugon Incandescent from Melbourne, (Carlton).

Lugon Incandescent from Melbourne, (Carlton).

One of Australia's rarest brands, Lugon, was a totally independent operator based in Melbourne.

Facts are difficult to come by, but they had at least two, if not three, plants across that city.

Although this example is a Low Voltage, 32v, 75w model, they are butter known for their Automotive Lamps, but they made 240v GLS and T12 tubes too.

The plants were located in the Melbourne suburbs of Carlton, Abbotford and South Melbourne. All have been demolished, but the one in Carlton was the last to go, only about five years back. I suspect one plant did the GLS and lamps like this one, another did the T12, and the third did the small automotive they were most remembered for, but determining which was which is very difficult. Carlton possibly had the greatest floor area. South Melbourne has been so built over and gentrified no trace remains, not even the section of street it was on!

One really unique feature of the full sized Lugons was the "ripply" shoulder near the base rim and butt-seal point. Most other Australian Lamps had a nice smooth cone on the shoulder.

its always interesting to hear of small makers that made fluorescent tubes

as fluorescent tubes are more complex then a "simple" GLS Lamp to make

do you know if the tubes they made where of a unique design or if they where made on machinery bought from a bigger company?

or if they where sourced entirely from another company but badged up as their own?

Thanks for commenting Bulb Freak.....I was starting to wonder if anybody ever would!

I have a Lugon tube somewhere deep in the shipping container...I have not seen it for a long time and last time I saw it, (c20 years ago) I did not know what I now know about Lugon so I do need to find it and take a "fresh" look at it considering what I have learned since the last time I handled it.

From memory, Lugon tubes....all T12s, were different, different caps, different cathodes etc. This suggests that they made their own and they were not re-baged...I could be wrong though.

I would challenge that fluorescent tubes are "more complex" than GLS.

Have you ever seen fluorescent tubes being made? I have.

The most complex part of a fluorescent tube is the electrodes with their CaO,SrO,BaO triple oxide coating and the need to "activate" them when the tube is on the manifold.
The second most complex part of the tube is the phosphor...this is all in the chemistry lab.

GLS lamps have their own complexities. Their internal structures are more complex mechanically than that of a tube.

The anti-arcing, thermally insulating, evaporation retarding nitrogen-argon gas mix inside a GLS lamp has much the same nuances as the mercury-argon Penning mix inside a T12 in a broadly speaking sense, but in a proper detailed sense the two mixes try to achieve opposites. The Penning mix in the tube seeks to initiate an arc discharge with ease whereas the mix in a GLS lamp seeks to avoid this at all costs...that is just one aspect, there are many others.

The gettering process of GLS lamps, using Phosphorus Pentanitride is technically comparable with the activation of fluorescent tube electrodes.

The molding of GLS bulbs using steam-film cast-iron molds is a FAR MORE complex process than the drawing of glass tubeing for T12's or T8's.

If you consider the amount of engineering development and scientific research that has gone into both types of lamp, I'd say it was about the same. If you consider modern Double Jacket Halogen GLS retrofits, the amount of research and development there would be quite a bit more than for linear tubes, but only slightly exceeding CFLi's.

I will try to direct you to some videos showing lamps being made so you can make more informed statements...

This should be enough to give you more links but it still won't give you the intricacies of the chemistry, dosings, mechanical tolerances etc.

James has a link page to most of these. http://www.lamptech.co.uk/Movies.htm

Happy Viweing...

indeed i have watched plenty of videos of lamps being made (you can even see my comments on a couple of the videos, I go by LightBulbFun on most parts of the internet these days)

you make a fair argument

what I guess I should say is

I have seen a lot of small manufactures make their own GLS lamps

but when it came to making fluorescent tubes, more often than not they just sourced in another companies tube, as I imagine its finically cheaper for them to do so, rather than setup yet another production line?

for example Crompton never made their own fluorescent tubes (AFAIK anyway), but they did make their own GLS lamps

hence why I was quite interested in hearing if Lugon made their own tubes

(when in Australia even the big 3 Osram Philips Thorn, all shared a common Philips design in 1 factory for the most part )

BTW apseaking of australia, James has updated his website with some new Australian lamp catalogs which have provided an interesting read

This two catalogues James posted recently were mine.

Possibly one reason why some smaller manufacturers avoid making tubes is the large volume and very high glass furnace needed to draw the tubing...it comes out an annular hole in the bottom of the furnace...which is high up on legs, than it is drawn off to one side and twisted...this takes a huge amount of horizontal space.

One of Lugon's plants was here which is far to small to draw T12 tubeing...this was possibly the automotive lamp plant..(they were best known for their Automotive lamps)..the other plant is gone...even off street view...there is international student accommodation units there now for nearby Melbourne Uni. Oh, no...got the other plant, just before it was demolished...I think the empty block on the left was part of it too.
There ias enough space here to draw T12 tubeing.

I'll just show you the site where ELMA drew their tubeing (both T12 and T8 )...In this long shed..the glass furnace was at the top...off screen (now demolished) and the phosphor wash room was lower right in the next shed...where it says "3D Earth" or thereabouts.

ah yes! just clicked with me now

while on the subject of this company, what GLS sizes did they make, did they make just common sizes or did they make a full 15W-1500W range?

clearly going by this 32V 75W example they did make some more specialized lamps

I have very few Lugons...least the 240v ones...but I do have a long neck 200 watter somewhere and a 60 watter in a 65mm bulb so they made all up to 200w...not sure if they made any bigger...never seen any...but any Lugon is rare!
