Since so many questions come up about landscape lighting, thought I would post a few pics of how the splices should be done, and what a real low voltage transformer should look like.

Is there really any benefit to using a toroidal transformer?

Quoted from Q-tran, the maker of the transformer pictured...


Toroidal transformers are more efficient than the cheaper laminated E-I types for a similar power level. Other advantages compared to E-I types, include smaller size (about half), lower weight (about half), less mechanical hum (making them superior in audio amplifiers), lower exterior magnetic field (about one tenth), low off-load losses (making them more efficient in standby circuits), single-bolt mounting, and greater choice of shapes. The main disadvantages are higher cost and limited power capacity.

I like those splices who makes them?

Also the conduit stub a lawn edge is a good idea. I wish my dog fence guys did that.

Not anything major !
A little less radiated flux,
A little more efficient.

Landscape lights don't care what tranny you use.

If there a cheap customer use a cheap tranny,

If the customer is a little more concerning use a torroid.

The spices are called ace connectors, one manufacture is King innovation, but you source them out online, they are not cheap, but the fail rate is very low, generally cause by installer error.

As far as the transformers are concerned, we do much bigger installs, so we do a lot of In grade transformers, meaning they get buried in remote locations from any structures, let's see you bury any transformer than a q-tran and see how long they last.

I thought you were kidding about Bahamas job. Nice road trip!!!


No concern of rain fall flooding out the transformers? My irrigation valve box gets flooded in big rainfalls as the ground get saturated and takes a while to perk away

No, Q-tran specially designed all of its housings for DB rating. They also have to withstand heat since they are contained, they rock.
