said by IIIBradIII:Yes but I believe the new "High efficiency" incandescents are halogen bulbs. said by itguy05:
Halogen lamps also emit UV.
Quoted in the original post:
"No effect on cells, with or without TiO2 NPs, was observed when they were exposed to incandescent light of the same intensity."
The comparison appeared to be with CFLs and their couterpart, which are incandescents, not halogens.
