Hi there. I just used one to test a power supply and noted that neither the -5 or -12 LED lit up. Is -12v important?

See my comments of -5V: http://www.amazon.com/review/RFNW9LHMC8WKU/ref=cm_cr_rdp_permAbout -12V, It's still on pin 14 of latest ATX V2.3 standard. I guess it's still needed.

I've had a similar issue. I'm not sure if it's important or not. If you look on the packaging you'll notice that there is NO way to contact the manufacturer. The only thing I can suggest is to call up a computer place and run that by them to see what they say, orr even call a place that sells electronic parts. If you do get a response, please let me know what they say.

They're all important, and any voltage that isn't being supplied will cause problems or just plain not work. That being said the less on these power supplies go out all the time so be sure your tester is working, You can do this by testing a power supply you know works

The 5w 12Vdc bulbs that I am using do not produce any RF that I can detect, In addition since they run off 12Vdc (I use romex 12 gauge wiring) there should be no circuitry changing the voltage to a higher level since the 12Vdc is adequate to power these LED's. However I have not seen the schematic of these bulbs (probably proprietary) so I am going on my experience with LED's in general.

The small details on the back simply show AP-10-12V. Not sure what that means but I'd be on the safe side and use a power adapter. Don't wanna burn out this baby

I dropped down from 12V to 7.5V without a heat sink. Not sure about a bigger drop.

I'm not exactly sure that I understand what you are asking, but here's my best shot. Hope it helps! Short answer: No. Long answer: If I understand this correctly you have 12V LEDs and a 110V dimmer? This power supply regulates to a target voltage around 12V optimally independent of the input voltage. Simply put, if you put 110V or 90V to this it should still output 12V. There is a voltage adjustment on here that you could use as a dimmer that lets you adjust the regulated voltage from 10-18V. So if you don't need a remote dimmer adjustment and this is enough variance for you then it might still work. Hope that helped, and let me know if you have any other questions!

Your psu tester should have stable green lights throughout .. Depending on what you are connecting. If it flickers, is it steady? I have to different testers just in case the psu tester is defective.

Negative, yet there is an input receptacle with NO SPECS as to polarity and voltage needed, as well a missing current spec needed when multiple items are connected. Closer inspection of item shows no specs ON the item either, but it appears that an area below the receptacle has been sanded off, as if the specs were removed, as was the model info. Weird.. Inspection was done with lighted magnifier I used at NASA to inspect pins. sort of like owning a 7-stall barn that will only hold 4 horses at best ;-)

It should operate with any 12v power supply and LED strip. As long as you don't exceed the 12A rating you should be fine. An FYI though, this product is extremely unreliable. I purchased 2 and they both didn't work.

My light just had brown (brown/red) and blue. I used brown/red for positive (red) and blue for negative (closest to black of options provided). It works. I didn't have yellow w/green stripe. Green is usually a ground, but don't know why there would be one on a 12v DC device.

Hi Dustin, 13.8-14 volts is ok, but please make sure the electric current is more than 400 mA. if current is less than 400 mA, the brightness will be darker.

This is a delayed contact closure, not a power supply. You have to supply power for it to work.From the picture it can handle upto 10A. Your led only draws 2A.

MattThese will work on no more than 4.5 volts.........real bright..........sorry i'm late....the other i bought from another company which i was testing were 12 volt they work nice.....but i bought only 6 for a test...........You would need a resistor to use those "the blue" to lower voltage to 4.5...........Rick

This is an LED kit made specifically for computers, so you would have to modify it and cut the power supply connector and make your own connection to the 12V battery to make it work.

Ground is one, 20A is other, I got mine working with 12v power supply and ground, still haven't had time to supply separate 20A 12v supply to power led lighting

I had a spare 12V, 3.75A from a Samsung monitor lying around so that's what I used. Almost any 12v power brick will do though.

LEDs can only be hooked up to a circuit one way. Make sure the longer lead (+) is hooked to the hot and shorter (-) is hooked to the ground.And you're probably burning out you LEDs. They're only rated for 3.2v, so if you're using a 12v supply without a resistor, you'll burn them up. You might get a bright flash as soon as you connect the power, but it won't work after that.

I use a 12 volt regulated power supply. The power inputs require bare leads from the supply. You will need to be sure your PS can deliver enough current to drive the number of led's you are connecting to it.
