Clip-on Blue dichroic filter
Clip-on Blue dichroic filter reflects back parts of the light spectrum so only blue light shines through. This vibrant blue light can be used to add drama to water features and modern garden materials such as glass and stainless steel. It also makes the water in a fountain, pond or other feature look much fresher if the filtration isn't perfect and the water is slightly murky or discoloured.
For 50mm diameter halogen and LED bulbs.
