Which? smart light bulbs test exposes security flaws

Smart lighting lets you control light bulbs from your smartphone and tablet, and gives you more options as to how and when you light your home. However, despite its benefits, you need to be sure that your smart lighting system is securely designed to prevent someone snooping on your data. That’s why we put all eight bulbs through a raft of security tests to discover whether they have the built-in defences to protect you from hacking attacks. Our privacy tests found that some smart bulbs simply don’t go far enough – or very far at all. In fact, the worst in this test earned a dismal one-star rating.
