A pair of LED Par30 Aquarium Lights. Approx 24 watts each. Gently used for a couple of months. These types of bulbs are engineered to last for years. They fit a standard light socket and can be used with many hanging fixtures. They have 7 bulbs: 3 'cold white' and 4 ~454nm blue, Photos show the exact item and include a 'demo photo' with the lights installed over one of my tanks (top tank).
