gordontech Posted April 26, 2012 Share Posted April 26, 2012 From what I got told there is a shape called "bulbus", so lamps in this shape are bulbs but something like a CP62 not being that shape is a lamp. Its the not all rectangles are squares and not squares are rectangles thing. Link to comment Share on other sites More sharing options...
Bobbsy Posted April 27, 2012 Share Posted April 27, 2012 Since I move between home (bulbs), TV studios (bubbles) and theatres (lamps) I've always been curious about how these differences got started--and also been worried at the derision that using the wrong "in term" can bring from professional lighting folks. I can understand all three. Link to comment Share on other sites More sharing options...
Brian Posted April 27, 2012 Share Posted April 27, 2012 I think people who insist on calling them lamps do so because they don't want to be called 'Bulbies'. I've had an idea. One of my on-line suppliers of these items is called bltdirect, as in 'Bulbs, Lamps and Tubes', so I'd like to propose that henceforth said objects are called 'blts' to avoid any confusion. Unless you're in a sandwich shop. Link to comment Share on other sites More sharing options...
sleah Posted April 27, 2012 Share Posted April 27, 2012 It must stem from the early days of gas lights and the invention of the electric light. When it was gas (I assume) they were known as lamps. When electric came along, the gauze was replaced by something 'bulb' or 'bubble' shaped that was replaced as a unit.As I understand it - and it does seem to make sense :blink: - the lamp is the part of a fixture (or lantern) that contains the lightsource unit, namely the connection to the supply (somekind of connector), the base (often ceramic), the glass bubble and the filament (or equivalent). The bubble became known as a bulb due to it's shape, similar to that which is planted in the ground. In days of gas you replaced the gauze, a component of the lamp, rather than the whole lamp. With electric you don't replace an individual component but pretty well the entire lamp, bar the socket that supports it. I may be a mile off the mark, but that's my interpretation based on hearsay, fact and figuring it out! :D Link to comment Share on other sites More sharing options...
GAZ THE SPARKY Posted April 27, 2012 Share Posted April 27, 2012 P.S. Gaz never heard anyone call them bubbles. In the tv/ film industry where I work most of the time they are known as bubbles If I work a theatre they are known as lamps and I get some confused looks when I ask for a bubble ** laughs out loud ** guess that that's because your Known as a lampie then if I do installation work for the general public then they refur to them as bulbs As stated earlier as long as you know what your refuring too that's all that matters Link to comment Share on other sites More sharing options...

timtheenchanteruk Posted April 28, 2012 Share Posted April 28, 2012 the common light "bulb" is technically called a GLS lamp.Which (until about 30 seconds ago, when I though, what the hell does GLS actually stand for) I did not know what it stood for, its General Lighting Service (lamp) as apposed to a candle lamp, or golfball lamp.

LeeStoddart Posted May 1, 2012 Share Posted May 1, 2012 In the theatres where I work we refer to bubble. But I agree we would still understand lamp or bulb. Let's not get started on fixture vs lantern vs luminaire Link to comment Share on other sites More sharing options...
rossmck Posted May 1, 2012 Share Posted May 1, 2012 Let's not get started on fixture vs lantern vs luminaire Since you started it ... the following is my own interpretation and opinion; Fixture - tends to be something that moves or otherwise requires DMXLantern - tends to be a generic and requires a dimmer circuitLuminaire - can be either, but more often generics....

david.elsbury Posted May 1, 2012 Share Posted May 1, 2012 Or "lamp" or "unit" (or "instrument" - think this one is more American?) Link to comment Share on other sites More sharing options...
jonathanhill Posted May 1, 2012 Share Posted May 1, 2012 I tend to use 'blub' for lamp, 'unit' or 'light' for movers or generics. 'Instrument' is almost exclusively American. Link to comment Share on other sites More sharing options...
paulears Posted May 1, 2012 Share Posted May 1, 2012 Why don't we agree to call them what the manufacturer puts on the boxes? GE call them lampsPhilips call them lamps I found a dealer called GBbulbs - they call them....... lamps. I then lost the will to live. Long live lamps!
