These high performance light and UV sleeves are available in four foot T8 and T12 options. Ergomart's TAPR50 sleeves are ideal for pharmaceutical, chip manufacturing and processes that require complete elimination of the "blue light" wavelengths. This product is also successfully used to control wavelengths that are detrimental to the health of people with severe light allergies and disorders exacerbated by wavelengths below 520.
It should be noted that this fluorescent lamp filter allows an orange red light that makes discerning the normal spectrum of colors with the human eye impossible.
Professional installation is recommended.
