  1. Decades ago I was obsessed with LED lighting being the future. This was just before they developed a true white LED. Then the breakthrough happened. I was working for Hawaiian Electric and my first thought was cost savings on electric use, but in the early years, the street lights that cost the company maybe $75 would have been about $750 for an LED version. The county paid the cost of the electricity and had an agreement with the utility to maintain them. So while the savings might have been good over time, the initial cost to retrofit the LED bulbs was more than anyone wanted to pay. Then the night sky initiative came out. Trying to keep all the stray light from going out into the sky and also the issues it caused from distracting night migrating seabirds in the islands, became a concern. They tried putting shields and changing the lights over, but the police complained that the new lights caused the colors at night to be different. Descriptions of car colors, clothing colors, etc made it hard for the police to get good descriptions. With LED white lights, the color shift wasn't an issue and the LED lighting could be designed to shine only where they wanted, eliminating the stray light into the skies. Fast forward a few years and LED lighting is very commonplace and widely used. I retired, but always felt like there was a great opportunity in LED lighting, I just didnt get on that money train.
