Having had mixed success with these AC electronic transformers, I dove in and decided to figure out exactly what's up with them. Here is what I learned, particularly for landscaping uses, but this applies to any use.

These are "AC Electronic Transformers" under the LighTech brand name, a product of General Electric (GE). They convert 120VAC into 12VAC/30KHz (30,000-Hz) This higher frequency means that you'll need a volt-meter that measures true RMS AC voltage ratings if you want to get an accurate measurement of the voltage on the secondary side of the device.

SPECIFICATIONS
Much of the information for this review came from the data sheet which I found online in PDF format. To find the datasheet google "let151-12 pdf" and it pops up in a couple of places. I know this is a GE product because the pdf has a website link on it in the bottom right corner for [...] which if you type it takes you to GE's lighting page.

Here are the specifications from a GE datasheet that are sadly missing from this particular LET-151-12 listing:

Just thought I would pass on something I learned to other DIY-ers. The output from these transformers is at a high frequency. My true-RMS meter would only see a few millivolts (AC or DC), but 12 volts of power was all there for an incandescent load. If you are using a voltmeter to check your install, you probably will not see the voltage on the meter.

We have 5 halogen 20W lights suspended in our kitchen. The power supply went out. Very detectable by the smell. A replacement price for the power supply was anywhere from $149.95 + S&H, another $19.95, to over $185 and free S&H. This transformer is an exact replacement from the same Mfgr. that supplied the lighting Mfgr.

Once you have the new transformer go to the big box home store by you with the pieces still together. They can steer you to what you need and if you don't have the tools they may be able to recommend a electric/electronic repair man you can use. Of course if you already looked for this tramsformer you probably can do the job. JUST REMENBER! this style transformer is self regulating amd must have a load close to it's rating to work properly. If you have 5 20W lamps don't think you can use 5 10W or LED's, damage could occur to your expensive lamps and even the transformer.

I bought this to replace a broken transformer on a track lighting on our home. We bought this and it arrived quickly. I was surprised at how small the unit was. Only took a minute to install and now my track lighting works perfect. Seem to be of good quality and will see how long it last.

I have 3, 35 watt pendants and 2, 20 watt spots all powered by new transformer. It instantly came on when switched and is everything I wanted. Delivered in 2 days as promised I couldn't be any more satisfied than I currently am. Thanks

I used this unit to replace the original transformer in my 12V halogen track light fixture. The original bulb configuration was for (2) 35W and (2) 10W, which I changed to (4) 35W which may have made the original transformer fail, even though it was rated at 150W. I have been using this new Light Tech for some time now with 140W total in bulbs and it has been working fine. This unit was small enough to fit into the ceiling mounted base unit that housed the original transformer which was a big plus.

I purchased this item to replace the one on my range hood. The original one that went bad was a WAC EN-12PX-AR that is no longer available. The new model to replace that one had bad reviews so I purchased this one instead. It runs the four 20 watts lamps just fine and works well with the dimmer. The unit is smaller than the original so new holes needed to be drilled. The order was shipped the same day. Very pleased.

It works, but construction looked poor/lack of QC. Housing felt weak and there was glue oozing out of openings, which makes me wonder about internal construction. That said, it works.
