I also can't get them in Chile anymore (since about 9 months ago). Reptile supplies are hard to get by here, but
at least before there were some once in a while. Since then, no more.
As a replacement, I have a CHE (ceramic heat emitter) and a LED which is not what should be used, I know, but I can't make those basking lamps magically appear in the stores here... and this at least makes light and heat despite separately and I put them next to each other.
I found some Zoomed 100W in other countries like Germany, and will get them from there soon (but that won't help you as I need 220V and thus looked for that voltage).
Maybe you can find some from other companies, don't know if e.g. Arcadia has some? (I can't get Arcadia here at all.)
Another option for replacement could be heat lamps made for chickens, but it must be the clear glass type. Most have a red glass, this is not to be used with reptiles.
Regarding UV tubes: There was no ban on those, but only on the coil ones which, however, are the ones that just shouldn't be used as likely dangerous for reptiles. The long tube ones which should be used are not banned.
