Hey y'all
So my uvb bulb got broken :( and I am in need of a new one. Right now I just have a fixture like this one https://www.chewy.com/zoo-med-mini-combo-dome-lamp-fixture/dp/154839
And one like this one but without the clamp

But from what I am reading I should get a tube light set up because the regular bulb types can cause blindness?
So what I am wondering is can I get a bulb for the fixtures I have that will be safe? Or should I get a whole new set up.
