Does anyone use these bulbs?
I know that most bulbs from the hardware store are around 4-5000Kelvin rating.
I am wondering what the difference is between those and the 10000-20000K bulbs that are recommended.
They will be for a Fish and Live rock aquarium with some invertebrates.
My main dilemma is cost, as I need 4 175w bulbs for my main tank and 50-100$ per bulb seems excessive.
