12-volts, 21 watts.
100
The wattage rating of a lamp bulb is a measure of the power it consumes, not the duration it operates for. The rating tells you how much power the bulb will use when it is in operation, but it does not provide information about how long the bulb will last before needing to be replaced.
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
The power rating of a light bulb is measured in watts (W), which represents the amount of electrical energy it consumes per unit of time. If a light bulb has a power rating of 60 watts (for example), it means it consumes 60 watt-hours of energy in one hour of operation.
Not a lot. The rating is to denote the voltage the bulb is designed for. The higher rating just says it will handle voltage that high so you have a bit more flexibility if your voltage fluctuates.
921
The main difference between a 194 and a 921 bulb lies in their size and brightness. The 194 bulb is smaller and typically provides around 2-3 watts of light output, making it suitable for applications like dashboard lights and interior lighting. In contrast, the 921 bulb is larger and offers a higher wattage, usually around 12-18 watts, which makes it more suitable for applications requiring brighter lighting, such as reverse lights or backup lights. Additionally, the 921 bulb generally has a higher lumens output than the 194.
To replace a standard 921 bulb, you should look for an LED bulb that produces approximately 500-600 lumens, as the original 921 bulb typically emits around 500-600 lumens. Ensure the LED bulb is compatible with the fixture and has a similar color temperature (usually around 3000K for a warm white light). Additionally, check for appropriate wattage equivalency; LED options usually range from 5 to 10 watts to match the standard bulb's output.
it's a 921 it looks like an oversized 158 bulb
i dont no but i need help what is the diference betwen 891 and 922
The factors of 921 are: 1, 3, 307, 921
Too much current for the rating of the bulb.
Please give the voltage and Ah rating of the battery and voltage rating of bulb.
921 = 92100%
The power rating of the bulb indicates how much power it uses. The power in watts indicates how much energy in Joules the bulb uses in one second. A bulb should have its voltage and power printed on it.
