The *total* max load should be marked on it somewhere. Because it is
externally the same as another doesn't mean much. So if it says 20w that
is the maximum.
Hmm, the only rating in watts on the transformer is 20w. I just find it
hard to imagine that a 5 way transformer would be rated so poorly, I
mean do 4w bulbs even exist???

I have several different LED transformers which have different power
ratings, but are all housed in identical boxes, with identical
connectors, probably because it isn't worth the hassle of
manufacturing slightly different boxes for each variant. The 5
connectors are probably only be there to allow higher rated models to
make use of them.

dan.
ok, so it is realistic that it is indeed a 20w TOTAL that the
transformer is capable of! I will buy an uprated model to suit my
requirement.

Thanks for all of the answers.
