Rhythm designs and manufactures indoor sunlight generators that reproduce the full strength and spectrum of natural sunlight. Their devices use a compact light engine delivering up to 60,000 lumens and 100,000 lux at 50 cm, matching direct noon‑time sun, with a warm 2700 K “golden hour” color temperature. The systems aim to improve health and wellbeing by providing sustainable, high‑intensity light for homes and offices.

Problem
Many people spend the majority of their time indoors under artificial lighting that is far dimmer than natural daylight, leading to disrupted circadian rhythms, reduced alertness, and poorer overall well‑being.
Solution
Rhythm creates high‑output sunlight generators that reproduce the full intensity (up to 100,000 lux at 50 cm) and spectrum of direct noon sunlight within indoor spaces. A compact light engine delivers up to 60,000 lumens at 450 W with 90+ CRI, while a copper vapor‑chamber and feedback‑controlled forced‑air cooling maintain stable performance and low noise. The devices emit a warm 2,700 K “golden hour” hue to evoke sunrise and sunset, and are hand‑built from aircraft‑grade aluminum for durability. Users control brightness and daily schedules via a tactile dial, allowing seamless integration of natural‑like light into homes and offices without additional software.
Target Audience
Primary customers are residential and commercial occupants—such as home users, office workers, and wellness facilities—who need high‑intensity, full‑spectrum lighting to support circadian health and productivity.
