I gave it less than the maximum because the lamp I ordered with the fitting was defective. After I rang them about it, they sent me another one of a different make. Also, if this fitting is being installed by a DIY person, the information that comes with it says nothing about connecting the fitting to the supply. The terminal block is not marked L and N and it is easy to get the polarity wrong with possible catastrophic results.
