With the heat you guys get over there like 35-40• an interesting experiment for one of you to try if yous have the correct gear would to be to leave it on the windowsill for it to get warm, and when the sodium goes to a liquid test it and see how far its warmed up? Lol

Yes it is unfortunately. I hate seeing old reliable technology discontinued. Especially when the technology that's replacing it is no better.

Its sad tbh. Over here in the UK some councils are struggling to get hold of these now. And have had to switch to either fitting SOX-LED lamps in sox lanterns or changing the lanterns to LED. They have no choice really.

There are Chinese manufacturers making SOX lamps. Or one manufacturer at least. The councils could import those lamps. It might be a bit more difficult than ordering from Philips but they could import in mass quantity. Then they wouldn't have to place another order for a while.

These are such fascinating lamps. Not only are they extremely energy efficient, they have a cool run-up process and make you go "colorblind." I actually used a SOX lamp for a light art project to produce a colorblind effect.

Philips DuraMax and GE Miser forever!  Classic incandescents are the best incandescents!

Yeah, the red neon glow you get from these when you first switch them on is quite a unique thing.

My very first SOX I got in 1980 from my High School...it was sitting on the windowsill in the Science Prep room just like this one is! It was this exact model.

Yes, Owen...You have created a Deja-Vu moment for me with this picture! The view behind was somewhat different however.

In the background here you see a couple of Japanese maple trees. An oak tree and my neighbors house. It was a bit of a challenge getting the lamp to balance in the window latch levers..

Blu-Tack does wonders to stop lamps rolling around when you try to photograph them.

Here is the school ...I got a lot of lamps out of it while I was a student there between 1977 and 1980 including two 10w 120v G.E. "Sign Lamps". one red and one blue.....how these 120v American Lamps ended up in this school, I have no clue.....I "rescued" them before some dopey teacher attempted to light them on the 240v mains!

The SOX lamp was almost directly (slightly to the left actually) under the small shadow on the roof from a fume-hood vent.


We have Japanese Maple trees here too...an imported specie of course...they go very red in Autumn.

Don't think we have to Oaks though.

That'd be interesting to try. Maybe I'll do it sometime..

I've seen Japanese Maples in garden centers here as well. They really shouldn't even be selling them since those are not meant to take the cold we can get in winter.

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

The sodium won't melt in the ambient room temperature as it melts at 96*C (208*F)...even the hottest place in the hottest room on the hottest day, 40*C (104*F) it won't happen as most of the lamp is transparent, (so the solar radiation goes straight through) or reflective to IR so that part of the solar spectrum does not get in at all. The vacuum in the outer bulb insulates the sodium in the arc tube from conducted heat from the air outside the lamp or any hot objects that might touch the lamp, like the windowsill.

Even in the hottest places, outside, like Death Valley of the Hammersely Ranges in Western Australia in summer of you bury the lamp shallow in the hot sand...the sodium just might melt.

If it were potassium...that's different, it melts at 63*C (145*F), then you might get some action in a dry sauna after a very very long time. Rubidium and Caesium are quite a bit lower again, (c35 and 28*C respectively) so these will melt on a hot day if the heat can get to them, but in the vacuum of the outer bulb of a SOX lamp, it still might take a while.


If you own more than one SOX lamp, the resonance imprisonment experiment is far more interesting and rewarding.
