5mm Led fairy lights. How to make a string of lights?

[Andrew2708]

Hi all, I am in a learning phase of making a string of lights using pre wired lights such as you see in the link below.

L125W 20pcs Pre Wired 5mm White Led Lamp Light Set 12V ~ 18V NEW | eBay

Size: 5mm Led, The wire about 20cm(L). Lens Color : Water clear. Light Color: White. Forward current (typ/max): 20mA/30mA.

Can you let me know how to make the string from these pre wired lights? Eg how do these connect to each other ? adapters etc so i can plug into a powerboard.

Thanks for you any help you can provide.

Cheers Andrew

It says they use 12-18V AC or DC. So get a power supply that can do that and attach away. This would be a parallel bus arrangement with each led attached to the appropriate leg of the wiring.

If you wanted to make serial connections, you will need to know the finished length you want to calculate the power supply needed.

Here is site that has the basics.

You're much better off buying a pre-made string from ebay or elsewhere than trying to make up your own.
For example https://www.ebay.com.au/itm/254771062854?hash=item3b5189e846 . You can get a string of 100 with a solar power pack or a string of 100 to run from the mains for a comparable price to 20 leds that you have to solder up yourself.

I'm with Alan on this one. You will get a fully working string at bunnings for less than what you would spend on parts hooking those leds up.
