leaking light fittings

[pipewood]

Hi all

I would like opinions/comments from electrical colleagues in respect to the following problem I have with garden spike lights which I installed for a landscape architect and having serious issues with them regarding the leaking of water into these fittings due to the incorrect size globe. This is my opinion about and I have also had reports from 2 independent lighting specialists confirming my opinion. Would appreciate your thoughts and comments.

Thanks
