Light mustn't be light, especially if there are warmth-sensible objects. In this case the clear light reflector lamp Decostar 51S by Osram is the right solution, just because it spreads the resulting warmth especially over the back of the reflector. This minimizes the warmth by 66% in the light bundle. Also warmth-sensible objects can therewith easier be pressed into the right gap.
Osram offers the Halogen reflector lamp Decostar 51S with GU5.3 socket with different watt performance power.
