These T5 replacement bulbs are an amazing bulbs to use in any T5 grow light fixture that is 4 feet in length, because they are linear T5 4 feet long bulbs that consumes 54 watts of electricity each hour it is burned. But for these 54 burned watts the lights lumen output will rank up to 4,500 lumens, and thanks to the technology used in these bulbs, the light output will be stable and consistent all throughout the 4 feet of the bulb. And also the great lumen to watt ratio of these bulbs make them not only very powerful but also gives them great lifespan that is rated up to 35,00 hours even in constant usage.
