This off-grid/interior RV LED bulb is perfect for bathroom lighting, kitchen lighting, closet lighting, dining areas, boat cabin lighting, and other RV or boat applications that accept A21 bulbs with E26/E27 medium screw bases. The bulb's low current draw also makes it ideal for off-grid living and renewable energy applications such as hydro and solar powered lights. Using 24 LEDs, the A21 bulb emits up to 1,130 lumens of warm or natural white illumination through a frosted lens. The LED light consumes just 13.8 watts of power; an incandescent bulb with comparable light output would consume 110-115 watts. This bulb operates within an 12-15 VDC range and is designed to last 33 times longer than incandescent bulbs. Price per bulb.
