Some people have attempted to remedy the fluorescent light problem by using incandescent light bulbs that are marketed and labeled "full spectrum." Sadly, even so-called full spectrum lighting is bereft (http://www.dinshahhealth.org). Turns out these bulbs produce light that is virtually lacking in yellow frequencies, an essential nutrient for the etheric body. The same is true for full-spectrum fluorescents. They are lacking in yellow as well as red, plus they produce dirty energy. In other words, they are nutritionally deficient and contaminated. Often these factors are hidden in advertising when manufacturers’ color charts are depicted using "averaged" frequency levels.
