5.0 out of 5 stars replacement for KTET-75-1-SCP-DIM
Reviewed in the United States on April 21, 2024
Size: 1 PackVerified Purchase
This KTET-75-1-SCP-DIM-HV-AL transformer is the exactly what I needed to get my under cabinet halogen light to work again. My light fixture is a Juno brand purchased in 2008 and has halogen lights. After it was determined that the transformer was the issue and not the bulbs for the light not working, I searched several electrical parts stores and kept getting told I should just switch to new lighting fixtures with LED bulbs because the part in my fixture, KTET-75-1-SCP-DIM, is no longer available. I really wanted to keep my halogen fixture so I would not have to replace all the fixtures under my cabinets, so I was very happy to find this KTET-75-1-SCP-DIM-HV-AL is the updated part number. My light is working perfectly again.

5.0 out of 5 stars Update- Still a great product
Reviewed in the United States on May 25, 2013
Size: 1 PackVerified Purchase
UPDATE- It has been ~ 7 years since I wrote my initial Review, and I am still exceedingly happy with this little product. It continues to work just fine in the JUNO under-cabinet light in our den. Just last week, another JUNO went out. This time it was a long 30” kitchen under-cabinet unit. Price to replace entire unit of that size was close to $200. I just ordered another Keystone ballast from Amazon. It arrived in a day, and since I knew already what to do, I had the dead ballast out and replaced it with the new in under 30 minutes. Problem solved! Savings of $185.! Bonus? The ballast is actually cheaper now than it was 7 years ago.

INITIAL REVIEW: Recently moved into home with JUNO under-cabinet low voltage lighting. One of the fixtures was not working. Hard to believe that all bulbs had burned out, but investigated that first. All bulbs were fine. Took off cover and with a little probing with a multi-meter, found there was no juice coming from the 120AC/11DC transformer. Called JUNO, and they told me "there are no end-user replaceable parts in our units. Toss it and buy a new one" Well, at over $110 a pop at our lighting store, I decided to dig some more. Manufacturer of the transformer is Keystone. Called them and asked what is replacement for my unit. . The one here, designated ------HV-AL replaces the original which lacks the HV-AL code on the end. The HV is for higher end voltage, 12V vs. 11V in original, and the AL means aluminum housing instead of plastic. Product arrived promptly. All wiring is the same as original, same colors and all. IN ten minutes, I had swapped out the dead transformer, and the JUNO light was back in full operation. Saved over $75 on that quick fix. The Keystone folks were VERY helpful....JUNO, not so much. Vendor was excellent, and kudos to Amazon for carrying this gem.

5.0 out of 5 stars Working Fine So Far

I'm not an electrician but this seemed to solve an issue I was having with a light strip. I think the other one failed and just needed to replace with correct specs and give it more room for cooling. The first was jammed into the wall. Poor installation and probably a fire hazard.

4.0 out of 5 stars Same as original, great price
Reviewed in the United States on June 9, 2014
Size: 1 PackVerified Purchase
Two of my kitchen undercounter lights had failed, new bulbs didn't fix the problem and so I contacted the manufacturer about replacement parts. Their response was that none of their fixtures had "user" replaceable parts and their recommendation was to replace the 2 fixtures (at $250-285 per fixture). The fixture consists of an aluminum housing, a switch, 3 - G4 light bulb receptacles, wires and one transformer. Frankly I'm rethinking the original purchase. I found the label on the transformer and ordered these for around $14 each and replaced them. Both of the fixtures have been running fine for weeks. $28 plus 1/2 hour replacement time vs $500 to $600. I'm pleased.

5.0 out of 5 stars Really a neat unit !
Reviewed in the United States on August 11, 2017
Size: 1 PackVerified Purchase
I received the transformer when expected, I haven't used it yet, but I tested it on the light I got it for and it worked great, I really like the compact size it should work great for for what I want. There is one thing I want to add, in the reviews, some folks said that they tested it with a volt meter and the output showed a low voltage, i did the same thing and got the same result's, so That's when I connected it to the light,and it worked, I hope this'll help.
