Just the other day, my daughter & I were shopping for kitchen cabinets at Lowes or Home Depot. It was after dark and the store lighting is far from bright enough, plus it's an awful tint and there are shadows everywhere.
Well, I had my Nichia 219b flashlight in my pocket. I explained to my daughter that this was no ordinary flashlight beam. That she could rest assured the color she saw would be accurate.
Sure enough, she picked out the cabinets! It would have been a wasted trip, had I not been carrying that Nichia.
