Can this lights operate by 9v battery? Instead of car battery?

Yes, I tested them with a hand held drill battery actually and they ran fine.

Not sure. The tag on the light listed a wide range of voltage 9 to 60 volts DC. I think it would run one of them as it is within the voltage range but I do not know how long it would go before running the battery down. This light is very bright but is a wide beam and not a spot. I have them mounted on my DR 650 trail bike but not hooked up yet as I am going to convert to LEDs as much as possible to save power and have the extra for other things.

Yes... as long as there is no transformer involved... If your lights have a transformer this will NOT work.

Understand you need a Transformer for the lights,unless you operating off 12 Volts DC. If you have a Power supplywith an input of 240 Volts and output of 12volts DC they will work.These lights require Low voltage D.C. to operate

they will get the power from whatever controller board you use, 9 volt battery can easily run 4 or 5 depending on how they are used and board they are connected to. They are not constantly on, only draw power when they are used.

I have them running off a 12 VDC battery in a vehicle, which is around 13.8 volts DC. If you use a 12 volt DC power supply it will work. MAke sure the output current of the power supply is sufficient to power to lights. IN other words, do not use a very small plug-in 12VDC power supply. Use one that is at least the size of a normal men's wallet. If you use too small of a power supply it could overheat the power supply. THese lights work fantastic. Theyve been on my vehicle for over a year now and continue to work flawlessly.

Yes these require 12v of power and they are tapped to an existing light source on the vehicle which you want the LED strips to turn on with.

The LED lights operate on A/C voltage between 85v and 264v. The low voltage system output is probably only 12v to 25v so these would not work. Some low volt systems may also operate on DC and again the 10 watt lights use AC.

Yes, assuming you're battery has around 100 RC (amps reserve capacity). The lights use 1.5 amps each per hour your battery should last around 5.55 hrs assuming a full charge and a good battery to full discharge. This is theoretical of course and many factors could lower that and likely will. Also make sure your fuses and wires are sized for the amps.

I don't see why you can't do that. You'll have to use like and end of an extension cord because these lights have a power pack which converts them from 110vac to dc

Sure. Any 12v battery will work. The length of time it will light is proportional to the capacity of the battery. These lights are pretty powerful so don't expect the battery to last very long.

I have connected it straight to a 9v battery and it works fine. It's not as bright as hard wired to a 12v system, but it does work.

These are for low-voltage only. they are not for use with high-voltage circuits. You should not have a problem because the lights do not have a photocell attached.
1485988
Yeah. If the battery gets used up just plug it via usb to your computer, 115vac, car usb converter...Lights go all disco too. Pretty cool imho

these are 12v lights ,it is possible if you put 2 lights in serie ,then they will work perfectly .

I haven't tried with 9 volts but if you intend to use a 9 volt battery better connect a resistor in series, there are guides on google to calculate the the value of the resistor to be used!

They are 12 volt, so any 12 volt power (car battery power) will power them. These will lose brightness after a few days of constant power though. Low quality LEDs.
