Will this unit work with 4-20v halogen lights without making any humming noises? Any problem with using a transformer rated at 105w with only 80w ma

A 105W transformer should pull a load of 80W. Normally the range of a 105W transformer is between 35 and 105W. If it is an electronic transformer it should not make noise. Some LED lights cause noises in such transformers. These are the cheaper types.

The minimum load on the 105W transformer is 20W, hence 80W is OK. The transformer has many built-in protections, like over-current, short circuit etc, hence no voltage is output unless a working lamp (20W or more) is applied. Regards buzzing, 98% of dimmers do not, but depends on the dimmer you have.

The Light is rated for 8 to 14 volt system. I had no problem wiring this light to my transformer that steps down 115 volts to 10 volts.

I am not an electrician but I also read that the minimum load was 50 watts. See: http://www.lightology.com/index.php?module=prod_detail&prod_id=17080 I have used the product for about 10 years for my low voltage lights and without a problem. The previous transformer, installed by a contractor, overheated. So I have been very happy with this product.

Nicola, I own the unit in the US and its great. I looked at the power unit attached to the ring and its 120v rated for 50/60hz. My hunch is it should work IF you use a better grade of voltage converter (120--&gt; 200v) to minimize any flicker. Cheers! Rick

The lightbulbs used are not halogen or led. The wattage for the transformer I have ranges from 7 - 11 watts using the wedge base bulb.

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.

Good morning, I would suggest buying a transformer that is rated 100 a watts more than your light fixtures. Also, if you are going to add any additional lights, now woul be a good time to figure that in do you don't have to buy an additional transformer down the road. Hope this helps.

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.

I believe so, but can't answer for certain. In my case, I just replaced the old fixtures, clamping in to the existing low-wattage line, and had no reason to check out the transformer. My previous experiene with low-watt lights required a transformer. Wish I could be more difinitive for you.

Cree customer support said "some humming is normal with our bulbs". She suggested ELV (electronic low voltage) dimmers, which run about SEVENTY bucks. I can verify by personal experience that if there are many bulbs or they are close to your ears, there can be an unacceptable buzzing with the $20-$25 "C-L" dimmers you can get at Home Depot. The Cree list of compatible dimmers is at http://creebulb.com/Content/downloads/product_info/cree_dimmer_compatibility.pdf Check for the ones that say ELV.

I can't answer your question because I do not know . I am using the transformer on a 35W halogen bulb with good results. Marvin Wasserman

You need a 12v transformer. Mine are direct wired transformers that I have up to four lights wired to.

My lights don't make any significant noise, perhaps it is the transformer you are using.

I bought this transformer from a Amazon seller for one of my project but it is not working, So I don't know if it works for LED or halogen.

It depends on what bulb you use and how many lights you want to use. The current rating of the transformer should be equal to the number of lights times the current rating of the bulbs. I use LEDs in my lamps so the current requirements are low.

Yes...there are different size transformers...but with any low volt or line volt lighting simply take the total wattage of the lighting strip..(60ft.) say maybe 200 watt....and divideby your voltage which I believe is 12v. on these...this would be 16.66 amps.....so make sure the wire you run from the transformer is rated at least 20 amps.....(#12 wire)This should work for you and be safe.....Make sure your transformer wattage output is equal to or less than your strip light wattage.

Hi ! Before you buy it check the " actual transformer for LED ". Check the voltage and the POWER required . Normally LED strings/strips are working at 12VDC . as I do not know your "LED arrangement" I cannot say if this transformer can be used for your application !
