Geeni’s Prisma Plus bulbs are a straightforward entry into smart lighting. They offer the core features most people want—color, tunable white, and voice control—without a hub. You just screw them in and connect to Wi-Fi.

At 9 watts, they match a 60W incandescent’s output efficiently. The color range is broad, letting you shift from a focused, cool white for work to a soft, warm glow for evenings. Scheduling sunset routines or controlling lights by voice with Alexa or Google is reliably simple.

Setup requires the Geeni app and a 2.4 GHz Wi-Fi network, which is a common but important detail. Once connected, the system is stable for daily use. For the price, this four-pack delivers a practical foundation for automating a few key rooms in your home.
