Perfect for bearded dragons

Have one of these lamps in my bearded dragon terrarium in use, and the little they love. In brightness, it is definitely not comparable with other lamps with 70W power approx.
Did they in 30cm distance mounted on a sun bed space, and integrated into the terrarium ceiling, so that the surface of the lamp to the ceiling flush and the bearded dragons do not get the idea to jump on the lamp.

In addition I have met as a ballast OSRAM PTi Electronic Ballast for 70W CDM HCI HQI HID Powertronic Intelligent 70W, because it is cheaper by more than half than the original and the same purpose. This starts and runs the lamp for a year without any problems and just as good as on the first day (and now I order the same again). Of course, while a corresponding electrical installation is provided by a specialist, because you can not fall back on the original connector system.
