10 bulbs per package---50,000 hours. Pure White only; 30ma. Now you can replace your old screw base bulbs with a 50,000-hour LED. I have made available replacement Led screw base bulbs for the three most common screw base bulbs in miniatures: The Flame-tip; the Candle base; and the Pea bulb. Each new LED bulb is specially made to illuminate a full 360 degrees looking very similar to the bulb it is replacing. The high intensity bulb draws 30 ma of current while the other three draw only 5 ma. These LEDs work only on 12 volts DC and thus have a polarity that has to be met. The threaded sides of the base are the negative contact and the bottom tip is your positive contact. For a new lamp being put into your dollhouse you can simply replace all of the incandescent bulbs with one of the new LEDs. When you connect it to the dollhouse 12-volt DC circuit you may need to reverse the two leads in order for the light to work. If the lamp has a plug, simply reverse the direction you are plugging it into the wall outlet and the lamp will work. For light fixtures already hardwired into your dollhouse, you have a 50/50 chance that when you replace the bulb it will simply work. If not, you might try flopping the two wires connected to the DC power source.
