Tulip
Solar powered garden torch
Context
Tulip originated from a formal study of real flames and candles.
The objective was to translate flame proportion, brightness distribution, and light behavior into a self-charging LED product, aligned with mass-production constraints.
Product
Tulip integrates flickering LED, rechargeable battery, solar panel, and dusk–dawn sensor into a compact head unit that operates autonomously.
A transparent diffuser controls light diffusion and optical depth, while the stainless steel body establishes a balanced vertical proportion. The two-part pole and detachable head reduce shipping volume and support both flat packaging and pre-mounted retail display.
Following the initial launch in 2015, the product evolved into a broader series with additional sizes, materials, and formal variations.
Tulip became a long-term commercial success in the outdoor lighting segment.
