The LED T5 doesn't just grow plants better than fluorescent, it saves money. With electricity savings alone each lamp pays for itself and saves hundreds of dollars over the 5-year warranty. Heat output is 45% lower than fluorescent helping save on HVAC costs. The LED T5 is not only superior to fluorescent lights but also to most other dedicated LED fixtures.
