I do often forget that IKEA has products and often alternative solutions to common problems.

Of course, they insist on doing everything in the "IKEA" manner, so the power supply is sold separately from the LED lamp units. Actual electrical specs are rather thin

Surprising to me, the power supply notes "To be completed with ANSLUTA power supply cord, sold separately."
