Gu5 3 mr16 maxiflood reflector bulb soft opal the highlight for this halogen reflector bulb is the reflector made of soft opal glass through this construction compared to conventional reflector bulbs it has a significantly larger ray angle of 100 the light does not only shine forwards as usual but rather also to the side and somewhat to the back this is particularly good for coloured lampshades because very special colour effects are created in this manner
