Alright so a pc light is a power compact light, standing for packing a lot of wattage in a small tube? the lights I have do have two connectors one on each side of the bulb, if I was to purchase a new hood / bulbs for this tank what would you buy if it was you, dont worry about price but dont get carried away with it. I dont mind spending money on this hobby because this is something I have wanted for a long time.
