I would say not. I had one (came with my beardie), and it was only 5% so too low anyway, but I left it in while I waited for my other one. It gave my poor baby very sore eyes, and I ended up just leaving him without for a while.
Invest in a better bulb, either a reptisun 10.0 (are you in Australia? You can order these from Amazing Amazon in Melbourne) or an Arcadia 12% (I had to have one shipped from the UK, but I love it). Preferably t5 and with a reflector (will work without, but you have to get the beardie much closer to the light).
Good luck! Keep us updated!
