Is this a regulated DC output? I want to use it with LEDs and a simple, rectified AC transformer output will burn out LED's early.

It is ca. 12 Volt AC output. Regarding CCI customer service, when I contacted them with my problems I wasn't given very competent help....maybe just the wrong person. I bought the following device http://www.youtube.com/watch?v=uvcHKqsK9Ew I am very happy. My bulbs are now getting about 11.5 volt DC. AC in/DC out with the device that I bought.

Your landscape transformer outputs 12V AC. You need 12V DC for the LED. I recommend you get one of these to get the conversion done. It is a very small device so makes it easier to hide.

I don't know the answer, as I don't recall finding that info. I can tell you I've been running 8 LEDs and (5) 7 watt fixtures for about a year with no problems.

I do not believe it is regulated DC. You should call/email the company to get the information you're looking for. (call CCI Consumer product hotline at 1-800-561-4321 or email questions to: consumer.service@colemancable.com.)

My input voltage is 124VAC and the output is 12.1 VAC, so I would have to say that the output is regulated. I would expect higher output from an unregulated transformer. (I am not planning to open the enclosure.) My DC LED lamps work fine, they have built in rectifiers and resistors to accommodate DC/AC 12 volts.

I'm wondering the same thing. It does NOT power my LED strip, and I'm wondering what's wrong.

As others have said, its the transformer. You need one rated for LED lights. If you merely switched out your lights for LED, then that's the problem. I had similar sounds and bought the Lighting EVER power adaptor for LED lights and it worked great.(http://www.amazon.com/gp/product/B004CEJ6NC/ref=oh_details_o03_s00_i00?ie=UTF8&psc;=1) No more sound!

It is a DC output, however I attempted to run 12 V automotive lights with it and it barely lit.

12VAC is delivered to the socket; that's normal after being stepped-down from 120VAC. Internally, of course, LED's use DC -- so, there's some righteous rectification going on inside that big old light-bulb.

I had three 3Watt LED light connected to a 12 Volt DC LED Power Suppply Driver Transformer and the lights keep burning out. Why?

Although these lights say 12V DC in the description, there appears to be a bridge rectifier inside them, and they work just fine on 12V AC. I have one connected to an ordinary 12V AC low voltage lighting transformer.

these LEDs run off of DC current only. Yes a AC to DC bridge rectifier will work. I have ran these LEDs off of DC voltages ranging from 5.5v to 14v but I had to be sure to calculate the current needed and match the power supply to the needs. Higher voltages usually supply less current. LEDs run on current.

It's regulated. Basically at 12v it pulls twice the amperage that it would pull at 24v. It allows for a consistent light output no matter the draw on the system.

I used a 12 volt 1 amp or greater DC transformer from the Goodwill store ($1.99); works well. LEDs are polarized so you have to get the + and - side correct or it won't work.9 Volts will also work; must be DC.

This transformer just makes 12 volts direct current output. Anything (lights, toys, etc.) that needs 12V DC would work fine on this, although I think this power supply can only deliver 150 watts of power--don't try to draw more than that.

Mine does not run hot. I am using all LED floods, 3 watt each, so probably not even 100 W for me. I changed from 20 Watt halogens in each of my lights, so significant reduction in draw on the transformer. I don't remember what it was like before.

The LEDs in this light operate on DC. The AC adapter/transformer is built into the unit, and cannot be bypassed.

No. This is a DC to DC converter. For your lights you would need a DC to AC inverter.

I might have been in error with my answer to Mr. Bruce questoon regsrding the 5V DC Regulated PS.It probably is a switching PS. It has a circuit that converts AC volts to DC and provides a stable DC voltage &current to the device.

could you please check and tell me what's the rating for the external DC supply ? Vdc ? and current rating (mA)?appreciate your help.thx

It is a DC output ! But I must have read that it had been a AC output, which was what I wanted. Didn't help me at all
