iPower 5 Pack 4FT 2700K 54W T5 Fluorescent Grow Lamp Light Bulbs.Man-made light sources experience some level of lumen depreciation over time. T5 Fluorescent bulbs will only depreciate between 8 and 10 percent of their rated lumen output throughout their lives.A key factor in switching to T5 lighting is its ability to not only produce better light, but also to do so while consuming far less energy.
