Stands for Power Compact. It is a type of flourescent lighting that packs alot of wattage/light into a small package.
The tubes look like neon lighting tubes and instead of having connections on both ends, they just have one connector.
So in order to take advantage of PC Lighting, you cant use your regualar Twin Tube Light Hood (just switch the tubes)??
Do you have to buy a totally different type of Hood that only takes PC Lights??
