Yep, you'll need both heat and UV light for your beardie.
Our tank is 4.5 foot long by 2 foot wide and 2 foot tall.
For heat, we use a Philips Spot One R80 100w bulb purchased from Bunnings for around $3.30 - it's much cheaper than a specific reptile lamp but does the job just as well. This is connected to a Microclimate B1 dimming thermostat.
For UV, we use an Exo Terra Repti-Glo 10.0 UVB bulb. Our UV bulb is right next to the heat lamp, above the basking spot. If you prefer to use a 'tube' style UV, the NEC T10 blacklight is meant to be really good.
Both the heat and UV light are on a timer which turns them on for 13 hours per day and off overnight.
We don't bother to cage either of our lights and have had no problems - the beardies are happy to sit underneath and bask, I have never seen them attempt to jump at or touch the lights. As far as substrate is concerned, sand is not good for young beardies but might be ok for older beardies. I personally prefer astroturf as it looks nice and is very easy to keep clean.
I'll try to find photos of my setup tonight.
Hope this helps! Good luck with your project
