Kapruka's Smart Bulbs and Lights sub-section carries Wi-Fi and Bluetooth-controlled LED bulbs, smart light strips, and colour-changing lighting systems for home automation. Smart bulbs can be controlled via smartphone apps or voice commands, and scheduled to turn on and off automatically. Those wanting home and garden books for interior design ideas can browse home and garden books. Smart plugs for other app-controlled home electronics are at smart plugs.

Smart LED bulbs use Wi-Fi or Zigbee connectivity to integrate with home automation systems including Amazon Alexa, Google Assistant, and Apple HomeKit. Colour-changing RGB bulbs can be set to any hue, useful for ambience lighting and nightlight modes. White-spectrum bulbs (tunable white) allow you to shift from warm yellow to cool white light, which is useful for reducing eye strain during late-night screen use. Key specs are brightness in lumens (800lm equals a standard 60W incandescent), colour temperature range, and compatibility with your smart home ecosystem. Voice assistants for smart home control are at voice assistants. Smart thermostats for home climate automation are at smart thermostats.

Smart bulbs are bought when setting up a home automation system, replacing traditional bulbs in a smart home, or as gifts for tech-interested home owners.
