Does anyone know if the 5V lead is necessary? All the spec sheets say "12V input". 5V lead may be for logic and lights?

It can be used for logic or lights.. all 12 volts are fully adjustable with the knobs.. from off to full load it can handle 2 fans each.. so thats up to 12 fans

The only DC Input is one 12VDC. All run from this single Power input. I do not see or was a 5V lead provide.

Yes, the DC 12V output is the 5.5 mm plug. However, the voltage coming out of that lead can get as high as 18.3 V on a clear sunny day. So you may need a 12V controller/regulator depending on your application. You may also need an adapter if your devices use a car accessory type of connector.

I have several of these units and have had no problems. I suggest you use a voltmeter to measure both the input voltage (should be about 12V) and the output voltage (voltage should go from about 0V to 12V as you adjust the knob from full dim to full bright. If no input voltage, check the power supply. If input voltage OK, but no output voltage, first check that you LEDs are working by connecting directly to the 12V power supply; If LEDs lite OK, dimmer is bad.

We appreciate your inquiry. An experienced electrician would be able to attach the LED Light Kit directly into a 12V source without an adapter. We do not suggest anyone tamper with wiring or electrical unless they are an experienced electrician. We hope we have answered your questions. We look forward to your order. Thank You

Well what you should be measuring is the current.... not the voltage. Yes it is working correctly. the current jump which is the main effect on your LED's at least is between those voltages

yes you will need a 12volt supply. The terminals are bare wire clamp ons so you shouldn't need any connecters. This is for single color LEDS not RGB version of LEDS.

They do make 12v led systems if that is what you need. Look up MR16 base lamps. They are the kind used in track lighting and in display spot lighting.

I can't answer about Arduino. I am using the PicAxe which can directly switch 12 volts, but can't handle any significant load. I run 5v to the logic side and run 12 volts to the control side of the picaxe. I also push the outputs to this board to switch other 12, 24 and. 110v circuits with higher loads. I will directly push LED circuits with the PicAxe and low load 12v.

Mine came with a presoldered lead with a barrel connection on the end. The other end of the spool had four pads, one is labeled "+12" and the others were blank. I removed the lead and desoldered the two wires. For each one of the other pads you attach to your negative lead, you will turn on one set of LEDs. If you look in the customer photos, you will see how I soldered on 4, solid core wires for control of each set of LEDs. When you connect all three pads to negative, it is the brightest.

It's output voltage is 5 volts DC (approx), to power an LED yes it can at 5 volts but you would have to add a DC to DC step up converter to get the 12 vdc

Thanks, i'll check for the switch on the back tonight. i'm sure the polarity is correct, red to lead (+) and black to ground (-) right?

I checked my batteries and both say "10.8/12 V" on them. I would suggest you recheck your batteries to see if they are the same as mine. I'm quite sure your batteries will work just fine for the light.

I recommend a 9v battery with a 1k resistor. You could fine-tune the voltage and resistance, but those are easy and quick numbers that I've tested on a string of 10 LEDs.

I expect yours is defective. Mine runs continuously on 14vdc from a little wall wart powersupply. A 12v lead battery fully charged will be at ~13.7 (14vdc). Note that your bulb is also designed to run on ~12VAC from a little transformer and no rectifier like a doorbell transformer. I suspect the bulb would have the same issue using AC power.

Mine came with a very short lead and without a plug. I replaced it with a store bought cord and plug. I'm using mine with 120 VAC household current and it works fine. I can't answer the lumen output question. For a 30 watt LED it isn't that bright. More like a 150 watt incandescent.

A typical low voltage system is just that, low voltage. This means they usual supply 12 volts to the fixtures. The 10W LED fixture requires 120V in it's current configuration. It's possible to do some surgery on it and see if it works with lower voltage, but that requires some know-how. I agree that it would be great. Hopefully LEDwholesalers will design a fixture to work with 12 systems.

Odd, my 12v model only had 2 wires, Brown and Yellow, and being 12 I didnt think it mattered which was which, but generaly, I chose the brighter of the two(yellow) as the +, and installed an in line fuse, works fine, bright as hell. Id rate it at nearly 1000 lumen when connected to my Deep Cycle 12v Boat battery.
