If they do that with some of these seemingly ridiculous low 'maximum loads' (e.g. 3W/5W), then it seems that they are thereby adding a level of idiocy to their 'not having a clue'!Some IKEA lights don't work when the maximum load is exceeded. One of the pendants I bought just had a PTC in the lamp base to stop you putting in a higher power lamp.
