Zoo Med Sun Plant Growth Bulb T8 17 Watts, 24-Inch

2 fluorescent brand new lights for your aquarium. One was opened but not used since I found out it was my hood that was bad and not the bulbs and had to buy a new one. This high intensity lamp with peak emissions in the blue and red regions serves to maximize the photo biological processes in plants. The emission spectrum closely resembles the absorption curve of chlorophyll-A, promoting maximum photosynthesis, ideal for planted aquariums, or terrariums.
