How much amperage do headlights draw?
Headlights typically draw between 5 to 15 amps each, depending on the type of bulb and the wattage it consumes. LED headlights generally draw less amperage compared to traditional halogen headlights.
Where can one buy a 12v LED online?
You can purchase a 12v LED online from the Amazon website. Once on the page, type "12v LED" into the search field at the top of the page and press enter to bring up the items.
How long does a 12 volt light bulb last with a 9 volt battery?
Depends. Whats the amperage rating on the bulb and the battery? Is the 12 volt bulb LED? The equation to find your answer depends on how much your 12 volt bulb is drawing and how much your battery has. I have seen 12 volt bulbs that are searchlights and I have seen 12v bulbs that are little LED ones. Huge difference in the amperage draw which will have a massive difference in your answer to how long your 9 volt battery will last. Same goes for the amperage of your battery. I have been in the military and seen 6 volt batteries that are smaller than a AA and I have seen the 6V at walmart that are decent sized and much bigger than a 9v.If you want to power your 12v bulb for a long time, connect two 6v batteries in parallel. That will give you lots of amperage and a full 12 volts.Another AnswerA 12-V incandescent lamp, operating at 9 V, will operate well-below its rated power and will, therefore, last much longer than it it were operated at 12 V. Further to the original answer, lamps don't have 'amperage' (current) ratings and is certainly unrelated to 'how much the battery has'! Finally, in order to achieve 12 V, two 6-V batteries would need to be connected in series, NOT parallel.
How much resistor should use for 20000mcd led?
Has nothing to do with the intensity of the LED, and all to do with the voltage/amperage of thediode, and the voltage of the system it is supposed to be used with.
What is the meaning of a 12v LED TV?
A 12v LED TV is a 12 volt usage Television set that is designed to conserve energy and be efficient at the same time. The 12v LED TV is suppose to give high quality resolution along with reducing your energy cost.
Can i put a 120V led bulb in a 12V socket?
yes
How long will a 12v 2.5ah battery run a 3w LED?
A 12V 2.5Ah battery can power a 3W LED for approximately 10 hours. This calculation is based on the formula: Battery life (in hours) = Battery capacity (in Ah) / Load power (in A). In this case, 2.5Ah / (3W / 12V) = 10 hours.
Is there any way to convert car led strips for wall outlets?
Probably a transformer that converts voltage from 120v AC to 12v DC. Commonly found at Radio Shack or an electronics store. Depending upon how much the lights draw for current, you have to find a transformer that will supply that current. Such as .5 amp or 2 amps or as much as 5 amps-----.
Where can I buy online a 12v LED TV adapter?
Target is by far the best place online to purchase your 12v led TV adapter. They offer exceptional quality at a reasonable price. The most preferred brand is Sony.
How can i connect 50 RGB Led's parallel to a 12v 2A line?
50 resistors
How many 0.25W led lamps can be connected to a 12V 500mA adapter?
You can connect up to 4 0.25W LED lamps to a 12V 500mA adapter. Each lamp would draw about 62.5mA of current. So, 4 lamps would draw a total of 250mA which is within the capacity of the 500mA adapter.
