Nice Build there things , looks like it should be on the side of a building someplace , I have put my 180W sox to the side atm as i have othere projectes going , as soon as its going ill get running pictures .
i wonderd though do you think mirrored acrylic would work as a reflector as im hoping to put my 18W Sox in a little acrylic housing .
55W and lower must be run base-up ±110°. Above 55W must be run horizontal ±20°.
The arc starts at the base of the electrodes because that is initially the path of least resistance. As the cathodes heat up, they switch to hot-cathode mode and the current will emerge from the tip instead.
Very impressive Things!
I took some shots of the Sodium lamps at work- they are much more monochromatic than the ones in my street so I think they are SOX. I might grab a little one and start out small - although I'm currently looking at some neon discharge tubes on Flea-Bay..
Cool on your light box
Yes I'm not sure about these, I have seen some smaller low pressure tubes around. Took it with the iphone which has very bad colour rendition as you can see from the cream wall turning blue as the camera tries to white balance.
Been looking at some of the Geissler tubes & small tubes with neon & other noble gasses.
If the colour in your first pic is right, then that is definitely a LPS lamp, however HPS lamps also have a pretty distinct orange colour, but not nearly as distinct as LPS.
@Things: Awesome polishing job! I drove past your general area today on the way to Mt Baranduda, I was keeping a look out for a yellow sodium glow, I would imagine it would stand out!
@Cyparagon: Yes lots of sodium in thoes pickles. Now i challenge you to get the pickle to lase!
