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. Also great for shy fish species such as Dwarf Cichlids, discus, etc. Use in conjunction with Ultra Sun® or Tropic Sun®. Zoo Med’s line of fluorescent aquarium lamps is made in Europe for ultra high quality, color, and longer burn life. Our energy-saving T8 sizes can save you up to $30.00 per year in electricity over the thicker T12 size lamps! Effective up to 10,000 hours.
