Here is what this last setup would cost me: approximately
12 LED's @$3.50 each----------$42 + $10 shipping (guess)
Heat Sink-------------------------$40 + $10 shipping (guess)
48 VDC Power Supply------------$30 + $10 shipping (guess)
Cooling Fan and 12VDC Power---$20 + $10 shipping (guess)
Miscellaneous----------------------$20 (guess)
---------------------Total---------$192
My current light, running 10 hours a day, is a single 55 watt PC
This LED fixture would use about 33 watts, saving me about 220 watt hours per day, or about 80.3 KW hours per year, at $0.17 per KW hour, saving me $14 per year. My bulb needs replacing about once a year at about $30 each time, with the shipping, for a total annual savings of $44 per year.
My enjoyment from making this is worth??? Priceless? Now, will that sell the wife?
