they come with 3.5w led mr16 3000K, customer may change them to high wattage light if needed.
if you need cable and transformer please check these 2 items out
Even after delivery, your recommended transformer is cheaper at Bunnings
Edit: cable is different model, so just transformer
Transformer same price as Bunnings ( cheaper than whats listed here) from Amazon with free delivery ( for Prime)
Not available atm, but I got some great spotlights at ALDI last year (surely coming up again soon) that looked better than these, and were $49.99 for 4.
I bought about 20x 3w LED spotlights for about $3 each.
Not really a deal.
