TopGrow’s 4ft LED T5s are intended to replace legacy fluorescent T5 vegetative grow lamps and work with existing multi-lamp T5 fixtures by offering a 5-year/50,000 hour operating life rating. Yet they use only 24 watts (W) per lamp which is over 50% less power and substantially less heat than the typical 54W fluorescent T5 bulb, while achieving a PPF Efficacy of 1.8 μmol/s/W.
