The ABI 18W is a reflector-shaped E26 grow bulb that screws into a standard lamp socket and runs on 100V mains. It blends red and blue LEDs into a full-spectrum output rated around 4000K, so it looks closer to neutral white than the blurple glow of older grow bulbs. The reflector housing pushes light downward, which suits a single plant or a small shelf rather than a whole tent. It is a low-power, plug-in option for houseplants and seedlings, and its 50,000-hour rating means it should outlast cheap blurple bulbs.
