Pos, i'm delighted by your new light, why are you using ledil reflector holders instead of cob holders for the cob's fixage? My last light also had them, but i'm not sure about their durability and pressure, so i decide to use only an ideal holders with reflector adapters.
What is the part number of those diffusers you have used in this light?
