TP-Link's new Wi-Fi light bulbs shun smart bridges for easier, cheaper setup

Smart lighting is a tantalizing idea, but many models require an up-front investment in "starter packs" that usually require an additional piece of hardware beyond the light bulbs themselves. These devices--known as a gateway, hub or bridge--often price smart bulbs out of the grasp of many potential users. TP-Link is joining a small list of smart light bulb companies offering products that are trying to change that. TP-Link recently announced the LB100, LB110, and LB120 smart Wi-Fi LED bulbs. All three bulbs can be controlled by TP-Link's Kasa app for Android and iOS without the need for additional hardware.
