I have admit that this modification is very interesting, although also very odd. Never seen this before.

Very interesting  , pretty much SOX converting in a HID fixture from Poland is something I have not seen YET. Though I did see a CDM Conversion from a Leda fixture as well, from a video which I watched half year ago, absolute a very fantastic design of a CDM optical refelctor was made for the CDM bulb.
