Very cheap and low power anchor lights
Well, Ta-Da! I was in the hardware store yesterday and what do I see? Led Christmas tree lights! 50 leds for 9 bucks. Any bets on what they gonna cost in January? red, green, amber, yellow, blue and white leds all on one string. Buy sone. Cut them up. Make your own low power lamps. You will need to figure out a current limiter resistor. It's easy. Been explained here many times. Sell your tungsten stock. Damn! I have been collecting tungsten from old light bulbs for years.

Very cheap and low power anchor lights
Are they really LEDs? Or tungstens that look like LEDs?
Reasons for skepticism: If you put 50 LEDs in series, you'd have all the problems of a series string with long life bulbs but 100 connections. If you put them in parallel, you have to have 50 resistors, each of which has to dissipate a watt (20ma times 115 volts but only on the half cycle) which is costly. If they're really LEDs, that's much less than the Radio Shack singles price, but more than their assortments. What does the package say? (I know that finding brands on cheap Christmas lights is futile, but there might be a clue). What store was it? What is the UPC? -- Jim Woodward www.mvFintry.com "Terry Spragg" wrote in message ...
