Ikea rack lighting has small halogen bulbs which fit very snugly into their lamp fitting. It is not possible to remove them with bare fingers. I tried a regular small suction cup but it was difficult to maintain sufficient grip. The handle on the small baller suction looked like it would be ideal.
As suspected the handle on the small baller was just the ticket. Was able to remove and replace two dead bulbs within 2 minutes.
The small baller is ideal when you want to grip small objects and have a handle to rotate the object
