I might use one of those for most days and a lizard UV lamp one day a week too (1 minute) But if you find a more affordable to the Sperti please let me know

Well, the 'active ingredient' in these things is the bulb and a reputable brand (Philips medical) runs about 150 euros for a 100w tube with a R17d plug: https://www.francelampes.com/en/30214-r17d-tl-100w-01-uvb-1760mm-philips-8718696662335.html https://www.francelampes.com/en/30214-r17d-tl-100w-01-uvb-17... You then just need the right ballast for it and a basic timer, maybe a reflector and stand and you're in business. Getting smaller qty is going to be an issue since these suppliers tend to sell in packs of 10. Apparently the a ballast runs about 70 euros and can power two bulbs. I might look into it since it's down right affordable compared to the alternatives.
