Spotted this on clearance instore at Richmond. Reduced from $29.99 and $60.
It's no longer on their website but I found this archived version with more information for the desk drawer lighting.
"To be completed with ANSLUTA electronic transformer and ANSLUTA power supply cord, sold separately."

You just need a 24V power supply, and some sort of connector.
You may also want a PWM dimmer in series. Or integrate into your smartlight system: https://www.ikea.com/au/en/p/tradfri-driver-for-wireless-con...
