This would be a great pickup for anyone running T5's on a fish only or soft coral / LPS tank as they still have plenty of life in them. All the bulbs are a mixture of ATI, mostly coral plus and blue plus, with the exception of 1 of the 24" bulbs being a lightly used coralife actinic and 3 of the 36" bulbs are new, unused current usa 10K bulbs. You get 27 bulbs for 20 bucks!
