The High Efficiency Solid State Lighting with Integrated Adaptive Control (HELIAC) system was developed to independently detect the presence of green plant tissue and to direct light only to those locations. During testing of the HELIAC system, a major factor interfering with effective tissue detection was reflectance of sensed wavebands from the walls and ceiling causing false positives. Since it is desirable to have reflective surfaces to maintain higher light levels with less power, selective reflection systems that absorb some wavebands but reflected others were tested. A test device was fabricated to measure the reflection of red, green, and blue light from a variety of colored mirrors. It was observed that both pink and purple tinted mirrors reduced the reflection of green wavebands more than red and blue wavebands. This effect could also be obtained by using colored films attached to a silvered mirrored surface. This technique was found to improve the performance of the HELIAC system in preliminary tests.
