Will Techmar's Low Voltage Garden Lights Work With My Old 12v System?

Will Techmar's Low Voltage Garden Lights Work With My Old 12v System?

Here you will see how simple it is to upgrade your existing outdoor and garden lighting system with the various connectors available in the Plug & Play range from Techmar.

Firstly, some important points need to be considered.

AC or DC?

The lighting fixtures in the Techmar Garden Lights range require AC (alternating current) to operate. 

The label below is from the 150w transformer and indicates the SEC: (Secondary or Output) is 12VAC and the Max Wattage achievable is 150w (150VA)

Low Voltage Garden Lights - 12v Transformer Label 
If your existing 12v transformer output is in fact AC the label should indicate SEC (output) as 12VAC (12V, Alternating Current)



What type of cable does my existing garden lights use?

There is usually an identification mark along the cable to establish what cable your system uses.

Techmar connectors are compatible with SPT-1 & SPT-3 type cables. These cables are popular among other garden lights brands such as Luxform.

Should you need to measure the gauge:

  • SPT-1 is 1/64 inch gauge
  • SPT-3 is 3/64 inch gauge
