How to convert old bulb to LED bulb There is a great quantity of evidence pointing to the energy savings of LED bulbs but in contrast they do have a particularly high price tag. Another factor in their benefit is long life and high reliability so how do you evaluate whether they are worth purchasing? If you want to get a correct perspective on the GU10 LED Bulb commercials you need to work out the total cost of ownership and use of LED Bulbs and compare this to established incandescent light bulbs. The advent of 12-volt LEDs with bases designed to fit most 12-volt bulb-holders makes replacing 12-volt bulbs a realistic task for people with little or no electronic knowledge. Here, let’s find how to convert a 12V Bulb to a LED Bulb.1Switch on the power supply to locate the bulb and the wires supplying electricity to the bulb holder. Use a digital millimeter to establish which wire is positive and which is negative. Connect the positive and negative probes across the bulb holder. If the millimeter shows a positive reading, the positive probe is on the positive wire. A negative reading means the positive probe is attached to the negative wire. Mark or label the positive wire. Now switch off the E14 LED Bulb power.2Remove the bulb and place it somewhere safe. Check the polarity markings on the 12-volt LED. Insert the LED into the bulb-holder so the positive side of the LED connects with the positive side of the bulb holder. Push the LED firmly into the holder but do not use excessive force. 3Switch on the bulb. If you connected the LED correctly it will illuminate. If the LED does not illuminate, switch off the power, remove the LED, turn it through 180 degrees and reconnect it with the polarity reversed. Switch on the power and check again. anty881209wong 140305
