UVB light recommendations for indoor guinea pigs

[h.h.lovecraft]

After listening to the wonderful webinar by John Chitty, I would like to invest in some sort of UV light for my indoor pigs to use when I feel like they may have not gotten enough sunlight. I was just looking online and I have little idea where to start. I know many people have great success with seasonal depression lamps in general and they sound like the easiest and safest option. Is there anything specific I should be looking out for? They range a lot in price. It would only need to be on for a few minutes I believe, and only really in one area of the cage, so I am assuming it doesn't have to be anything large. I know UV bulbs (non heat producing) are also popular with some animals, but that feels like it could be less safe and generally more difficult to set up. I live in Germany, so specific products may not help me, but I know other members have questions about it, so feel free to share if you've got a recommendation! I looked through the forum and while there are some posts on the topic, not many recommend anything specific. Thanks everyone!

Tagging @Tara95 because I know they also had questions about this

I listened to a few webinars by a German vet last year who also recommended UV lamps, but when I talked to the specialist vet at the university of veterinary medicine in Vienna about it who is always up to date on the newest literature, he said that their are no established guidelines (yet).
But I'll have a look into the script if she gave an example of a lamp.

I found it.
She recommended 'Namibia Terra 160' lamp, distance 50 cm, usable for about 2 years. I didn't find a specific time per day in the script.
And the lamp was called 'Ferkellampe'.
But I never looked into this subject any further because the specialist vet didn't encourage me to do so.

Thank you for the information, I will definitely look into it. I know there isn't a lot of concrete information about this yet, but I figure it can't hurt to turn on the lamp for a few minutes once in a while if I feel like they could use it. I also wouldn't mind getting a seasonal depression lamp to use for myself as well, since I barely see the sun in winter However, I'm not sure if they are as effective as uv bulbs specifically for pets and reptiles like the one you specifically mentioned.
