DIY MH E-ballast cage

The MH E-ballast gets pretty hot while in use and almost got burnt when I accidentally touched it while shifting things around the power point. The cage is constructed from eggcrate (light diffuser) and zipties. Benefit of this cage is that it will prevent accidental touching of the hot e-ballast surface, it is well ventilated with the large holes as well as allowing the eballast to be positioned vertically to allow maximum heat dissipation compared to lying flat.
