Bracket to mount the Philips pongee dual light directly to the ceiling without the need to drill holes in the ceiling. The m4 bolts from the conduit ceiling box (with 60mm spacing) can be used to mount the bracket to the ceiling. 

V2 uses the slide on brackets that came with the light. however, this design is less stiff and can result in some sag of the light with respect to the ceiling.

V3 is much stiffer, but requires some support in internal cavities that is somewhat difficult to remove. For this version you can take the grey pins from the bracket that came with the light (push inward and do a quarter turn of the pin, and release).
 

If you decide to make this model, let me know what you thought of it! I would appreciate some feedback and a make!
