The Red powerPAR LED Bulb allows you to give your plants usable light in the red wavelength (610-710 nanometers) for the flowering growth phase. With low heat generation and light output equivalent to 130 watts of traditional incandescent grow lights. These led grow bulbs are ideal for supplemental light in flowering. An application would be to set up several powerPAR bulbs pointing into the lower canopy to enhance yields. The energy consumption of these bulbs is low, and their service life very long—50,000 hours—making them cost-effective for supplemental lighting applications. And they fit into a standard incandescent light socket, making them easy to set up with a common spotlight, work light, and other fixture types.
