Does anyone know the actual amperage draw on these? I know it's low b/c they're LED, but each plate has 6 LED's and I plan to use 9 plates (54 LED's)

The label says 1W. I plugged one into a kill-a-watt meter and it shows .02 Amp. (20Ma). Problem is it show this regardless of the switch setting or whether the LED's are on or off.... This unis has not been plugged in so the battery may be charging. I will leave it plugged in and update this info after the battery has had time to fully charge.

These LED's only have two leads. The longer Lead is the Anode +,and the shorter Lead is the cathode - . Use a 1/2 watt 1k resistor in series with a 12 volt supply. The LED flashes and changes color all on it's own with a built in microchip. It looks like a tiny black speck inside the LED. It has no effect on the brightness. I think these Led's are a great buy for the money. They did not come with 1 k resistors. I forgot what they came with. Important you use 1 (1k ) resistor per LED in series. Look up charts on LED's brightness,current draw , voltage and proper voltage drop resistor for you application. These LED's only have two leads.

Just took a multi meter to them while off. It read 0.5 ohms across 3 LEDs @ the cut points... Hope that helps.. Doesn't seem right to me for some reason...

Calculating amps would be difficult, that said, my entire strip pulled under 2A if I recall correctly and a shorter section that I cut pulled proportionally more current since the resistance of the copper wiring was less over all. I would recommend supplying the entire strip with a 3A power supply and each smaller section (say around 1 meter) with a 1A wall wart power supply just to give a healthy margin of error and maximum possible brightness.

LED takes 5 Watts for 40, 7 for 60, and 9 Watts for 75. They will save you money on your electric bill

yes LEDs are great! We have them in there now. I think it's technically supposed to be 25 watt but if you use LEDs they will be less than they need to be anyways.

The cables are dimensioned so you could pull the full amperage. I think there are twin cables for ease of wiring two sets of LEDs. If in doubt though, hook up your load to one cable and see if it gets warm, or just splice both cables into a single cable.

the power supply shown here would only run ONE LED strip. Each strip (Amazon item Triangle Bulbs T93007) uses 25 watts at 12 volts DC which is 2.1 amps So 6 strips would use 150 watts or 12.5 amps. You would want to up those ratings by at least 20%. However I suspect the internal wiring structure of these LED strips is too light to carry more than two strips connected together. Two strips would be 50 watts or 4.2 amps at 12 volts dc.

I just was checking my 16 FT SMD5050 LED rolls and they run about 1.7 Amps each. For good practice, calculate power supply needs at 2 Amps to allow for some spare capacity. So for 2 cords, that is 4 amps. Since watts are equal 12 volts multiplied by 4 amps. P=VI 48 watts. Probably rated 50 watts. Since this supply is rated 6 Amps, it should be plenty robust.

They draw about 2 amps each, so if you wire them into your reverse lights, just 2 of them should not draw more than most vehicles are wired for. They'll be more than bright enough.

I've driven three strips at once with a pack of 8 AA batteries. What that is in terms of amperage, I don't know offhand, but that should be able to be computed.

Don't know about power usage and these are smd without resistor don't buy them unless its for car,RV etc.. look elsewhere on Amazon for bulk led packages

Most led's like this will run at a varying voltage. Usually this style will work with 4~18 volts at least. They may run slightly dimmer but it will most likely be not noticeable. If you would like i can go hook mine up to a 6v DC power source and see how they act. ( i bought them from here, decent lights, not the best of quality, wire isn't copper and a very very small gauge. I soldiered my connections because i was worried about the wire just breaking off without the insulation on it.

Are you talking about LEDs, or LED drivers? The numbers you quote seem more typical of LED drivers than of the LEDs themselves. Either way, this power supply is not going to drive 10 of them in series, as the voltage per unit would be too low. A combination of series and parallel might work.

I'm running 22 lights in line now off of one power supply. You can get an extra set without the power supply and add them to your string. If you want to run more than 24, then I recommend splitting the power source and using two power supplies.

the short answer is yes. i am not sure the amperage draw of the lights. I have mine on a 10 amp fuse.

I am not sure wgich strip you are asking about. I bought the 300 led's and 600 led's. They are 24 watt and 46 watt. You need to use at least 2 amp for the 24 watt and 3.5 for the 46 watt. The formula to use if I remember it correctly is : Watts=volt X ampSo, at 24 watt, you divide 24 watt by 12 volts and you get 2 ampsHope this helps
