powerPAR LED Bulb-Blue 15W/E27 The Blue powerPAR LED Bulb is Hydrofarm's exclusive spectrum-specific LED bulb for blue color. It allows you to give your plants usable light in the blue wavelength (450-495 nanometers) to boost their growth in the vegetative phase. With low heat generation and light output equivalent to 130 watts of traditional incandescent grow lights, they are ideal for supplemental light. An application would be to promote thicker and sturdier branches by setting up several powerPAR bulbs pointing into the lower canopy. 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 common spotlight, work light, and other fixture types. Low energy consumption 50,000 hours life span Low heat generation Fits into standard 120V socket Arc shaped for wider beam angle 130W Incandescent equivalent General coverage area: 2' diameter 12"-18" above crops.
