I like VHO
actinic much better than PC
, but it's definitely a personal preference. For many years, only VHO
's offered a "true" actinic spectrum bulb, where it was not available in PC
's. I think recently a "true" PC
has been developed; make sure you look for that if you are looking for actinic supplementation.
Maybe someone here can point out how you can tell the difference ... I'm not sure.
