Grocery giant invests in exit signs that put high-tech spin on glow in the dark
The Kroger Co. is installing cutting-edge exit signs as part of a $4 billion store- investment program. The chain is deploying photoluminescent exit signs developed by Cincinnati start-up MN8 at all new and renovated stores nationwide. The LumAware signs differ from standard glow-in-the-dark products in that they also emanate light. The signs, which consumer no energy, eliminate the need for batteries, light bulbs, electricity or maintenance.
