That depends on the current. The formula P=IV (where P is power in watts, I is current in amps and V is voltage in volts) is how you calculate the power. So if the current is 2 and the voltage is 3 then P=2x3=6Watts. Use an ammeter to determine the current.
A thought. You may need a converter to change over to LED. I needed it for my motorcycle.
LED: light emitting diode. It is a diode that emits light when current passes through it
Light Emitting Diodes (or LED's) serve many purposes, such as statuses (EG Computer is powered on, PC is reading from Hard disk (Power and HDD LED's)). They can also be used to display messages (LED Boards) New age brighter LED's are used in the Audi and BMW cars as sidelights. 4 L1GH7 3M1771N6 D10D35 1S C001

It actually means Light Emitting Diode. I hoped i helped :)

To calculate the current draw in amps for a 48-watt LED light at 12 volts, you can use the formula: Amps = Watts / Volts. So, 48 watts / 12 volts equals 4 amps. Therefore, a 48-watt LED light at 12 volts draws 4 amps.
If a light bulb is rated at 60 Watts, the voltage will depend on the specific type of bulb. For a typical incandescent bulb, the voltage would be around 120 volts. However, for an LED or CFL bulb, the voltage could be different, such as 120 volts or 240 volts.
You need the volts times the amps to equal 100 Watts. On 12 v that is 8.33 amps, or on 200 v is it 0.5 amps.
A: WELL you cannot not with 1,2v most LED start emitting at 1.8 v some as high as 5 volts . two need at least two 1.2 volts better is 9 volts then there is a problem voltage wise but the problem is now that you need a limiting resistor to ensure at least 10ma of current
It depends on the color of the led you have. Normally it changes between 1.5 V and 2.5 V. But if you need to use white or purple leds those leds need more power like 4-5Volts. Im gonna calculate for a standart red led, a red led needs 20 mA and 2 volts to light up. So we know the formula that we can calculate how many watts does the led need, P = U * I P = 2 * 0.02 = 0.04 W. I used the average values. I hope I didnt make any mistake :)
The number of lemons needed to light up an LED depends on the type of LED and the voltage it requires. Typically, a single lemon can produce about 0.5 to 0.9 volts, so at least 2 to 3 lemons connected in series may be needed to generate enough voltage (around 2 volts) to power a standard LED. However, the exact number can vary based on the lemon's acidity and size.
Just under 2 volts
No. Volts is the "pressure" of the electricity. If a single 3.6v led required 20 milliamps (amps is the "amount" of electricity) you would need to supply two of them with 40 milliamps but at 3.6 volts.
Depends on the led forward bias threashold, if its a typical led it will be .7 volts so, .7x6=4.2V, so pick a resistor that will drop around 7 volts. What is the current? Then just to V=IR, 7=IR.
To calculate the power usage of an LED light, you need to know its wattage rating, which is usually indicated on the packaging or the light itself. The power usage can be calculated using the formula: Power (Watts) = Voltage (Volts) × Current (Amperes). For example, if an LED operates at 120 volts and uses 0.5 amps, its power usage would be 60 watts. Additionally, you can estimate energy consumption over time by multiplying the wattage by the number of hours the light is used, converting it to kilowatt-hours (kWh) for utility billing.
LED light color can change based on the voltage applied due to the characteristics of the semiconductor material used in the LED. By adjusting the voltage, the energy level of the electrons in the semiconductor changes, causing the LED to emit light of different wavelengths and hence different colors. This allows for the color of the LED light to be controlled electronically.
