What are we (reptile owners) supposed to do when halogen bulbs are no longer produced?

In the EU, it’s rare to find a place with halogen bulbs because they are no longer produced or imported. Some shops have some bulbs, but only as long as they have them in stock.

It’s all about being eco-friendly.

Are there any light and heat sources that can replace halogens and incandescent bulbs? It can't be more eco-friendly to use multiple items to produce heat and light in the long run.

They certainly can’t just remove all reptile bulbs, etc.
