Compact fluorescent light (CFL) bulbs can provide the same amount of lumens as incandescent bulbs, using one quarter energy. Recently, CFL exposure was found to exacerbate existing skin conditions; however, effects on healthy tissue have not been thoroughly investigated. In this study, we studied illumination human cells (fibroblasts and keratinocytes). Cells exposed CFLs exhibited a decrease in proliferation rate, significant increase production reactive oxygen species, their ability contract collagen. Measurements UV emissions from these levels UVC UVA (mercury [Hg] emission lines), which appeared originate cracks phosphor coatings, present all studied. The response consistent with damage radiation, further enhanced when low dosages TiO(2) nanoparticles (NPs), normally used for absorption, were added prior exposure. No effect cells, or without NPs, observed they intensity.
