Following suggestions made by forum members I have produced a glossary of some of the technical (and not so technical) terms used in streetlighting. I have included a few column manufacturers as some members may not know what is meant by a Stanton column for instance. Please feel free to make additional entries by PM and I can edit the list rather than having lots of extra posts. That way the information is all together and easier to move at a later date. When the reference section is up and running this can be copied across and maybe able to be turned into a Wiki.

Again if anyone wants  to PM their entries I can collate them into a single post as for the main glossary.

 Arc deflector:
    Allows MA lamps to be operated horizontally
 Ballast:
    Reduces mains voltage to match lamp operating voltage and assists in providing striking voltage to start lamp. Traditionally of magnetic type

    Bayonet cap
 Bracket:
    The top of the column, often at right angles to the main tube and of smaller diameter to which a streetlight is attached

Listed below are the most common types of current production and out of production but still in use lanterns. To aid identification, SOX types have wattages listed as often only 1 size of lamp can be used, especially for main road types.

SON lanterns do not have wattages listed as most types can take a variety of lamps. Practically all SON lanterns are able to run metal halide.

Lamp type is the most common fitment (but with the general exception of SOX lanterns), most lanterns can run practically any lamp type.

Lanterns can either have integral gear or remote gear, some manufacturers denote integral gear with a change of model number, others don't.

For datasheets and technical information on lanterns try Simon Cornwell's site.

For photographs of lanterns try Claire Pendrous or Tim Luckett.

The GEC Z8536 geared Turtle is still made by CCH of Bangkok, Thailand. It's now their HS3 model.

Scoll down to see the CCH HS3 model:

Just out of interest which do you think is a better term to use: GLS or Incandescent?

The OED defines: Incandescent - Light produced by a glowing filament

So I'm going to keep it incandescent and have added that term and GLS to the glossary. Other changes have been made (and the corresponding posts deleted).

Ah I see, so GLS (the standard tungsten filament lamp) is a type of incandescent lamp. Cheers.

Good point actually. When I first started reading streetlighting websites I didn't realise what a GLS lamp was for a while. After some time I figured out it must mean a bog-standard tungsten lamp.

Thanks for posting what GLS stands for Phosco as that would have been my next question!  :lol:

From my short time in the lighting industry, I always understood that GLS stood for 'General Lamp Shape', hence the characteristic bulb shape associated with it.

I prefer the term Incandescent or Tungsten. Never really took to calling them GLS.
