Yup, Metal Halide is MH
PC = Power Compacts. VHO (Very High Output) and T5 are all basically flourescent lighting. Actinic is basically a color if you will - the "blue" bulbs you see, generically
are "actinic" bulbs and basically enrich the blue wavelenghts available in the tank. This is because blue wavelengths dominate on a reef because red light is absorbed very quickly in water. So boosting the blue spectrum is trying to recreate a natural available spectrum for photosynthetic reef animals.

The actinic lights are usually pc's or flurecent or are those two the same ?
thanks
Yes, actinics are Fluorescent. Fluorescent is a type of light bulb. Technically, PC, VHO and T5 are all fluorescent bulbs. PC and VHO are older technology than T5. T5 bulbs are much thinner than PC and VHO and can put out more PAR (the usable light from a bulb) than PC and VHO. They key with T5 is to get a good reflector for each bulb.
