I realize this is not for everyone, however we are saving $250-300 monthly in our museum using this dimmable par 38 replacement. Soon the prices will plummet on all types of LED's including soft white for 100 watt replacements. And they last forever we are told. They are expensive now but I guarantee the market will take care of that.
If I was 25 again I would be going door to door selling these products. And if some bright American actually started manufacturing the product in America......well that's a topic foe another time.
