Smart lights that react to voice commands spoken to smart speakers are old hat, but a smart light with a built-in AI microphone? Showing off its wares at the IFA trade show in Berlin this week, Germany-based smart device manufacturer Lepro is teeing up a quartet of "AI Lighting Pro" lights that can set the mood based on your natural-language prompts--anything from "Give me an Iron Man vibe" to "Set a cyberpunk city theme." Each of the lights features a built-in microphone that captures your commands (you must say the "Hey Lepro" wake phrase first) and processes them using Lepro's new LightGPM AI engine, a large language model that's trained on "color psychology and lighting design," Lepro says. The AI then delivers an "ideal" multi-color lighting scene based on your voice prompt. We've seen plenty of smart lights with AI-powered light scene bots before; Philips Hue is integrating one into the Hue app, and Govee and Nanoleaf have their own versions.
