I just got my first Beardie ever, so I'm a bit worried about my lack of knowledge. I just set up the tank, I have a light, UV light and a heat lamp. The heat lamp doesn't actually have a bulb in it yet, they didn't tell me that in the store so now I need to get a bulb for it. What bulb should I get? Also I plugged in the UV lamp and it looks exactly the same as when it's off. How do I know if it's on?
