There are handheld UVB 311 nm dispensers, which are not as efficient as whole UVB spectrum for Vitamin D production but still work and are safer.

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:

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.
