Field evaluation of a safety-by-design protocol for SELV LED illumination in edible dessert bouquets: pilot results on aesthetics, workflow, and safety outcomes

This pilot field study evaluates the first practical implementation of a previously published safety-by-design protocol for integrating SELV LED illumination into edible dessert bouquets. Two consecutive operational periods were observed at a single studio: a baseline period without LED illumination (48 bouquets, four staff members) and a subsequent period with SELV LED components installed under IP44+ ingress protection (42 bouquets, the same team). For a convenience subsample of reference bouquets, illuminance, assembly time, rework events, aesthetic ratings, customer feedback, incidents, and checklist adherence were documented. Mean illuminance increased from 225 lx in baseline reference bouquets to 393 lx in LED bouquets (≈75% relative gain) while assembly time changed from 31.5 to 33 minutes. Mean aesthetic ratings on a 1-5 Likert scale increased from 3.5 to 4.5. No product returns occurred in either period; one LED bouquet generated a brightness/flicker complaint and a near-miss incident, leading to proactive replacement of the LED strip before delivery. Compliance checklists were completed for all baseline reference bouquets (100% adherence) and for one of two LED reference bouquets (mean adherence 92.5%), which allowed the non-conforming configuration to be detected and corrected. These results demonstrate that the protocol can be implemented in a real food-floristry setting, leading to higher perceived aesthetics and structured documentation of safety performance.
