In early 90's, we did the same for our Astronomy business, crushing hundreds (thousands?) of white bulbs. Replaced with red LEDs for flashlights to make star chart reading possible, without losing night vision. Wow! We sold LOTS of red light, dim-set LED flashlights. We undercut the better advertised national companies, so made some money. Would have sold more, but the ones we made were so dependable, we didn't get many repeat customers. We did get lots of people referred by customers, tho.
