Study on the Influence of Tunable LED Lighting Systems on Consumer Food Label Perceptions

Abstract

Consumer perceptions of meat package label design variations under varied LED lighting settings were measured in a grocery store simulation lab at a big Midwestern university. Participants' responses to the novel meat labels were measured using a quasi-experimental approach that used a multi-group between-within subjects' post-test only design. Over beef steak box labels, Philips HUE consumer LED light bulbs were modified with different colours from 2700 K (RED) to 7000 K. (BLUE). Goose neck lamps over the packages were used to create the display lighting simulations. The researchers discovered that label and illumination interactions altered consumer perceptions of nutrition label information both across and within subject groups. LED lights remain cool compared to thermal effects from older fluorescent and metal halide technologies while reducing energy costs. LED lighting systems with substantial color variability will increase in importance and use in retail store lighting designs in the future.
