Hello Ghostcat,
This product should be a maximum of 10W consumption at 12V. If they are higher than this then yes they may damage on the transformer which is why we ask that if you feel you have received the wrong product, we would suggest returning the product to us for replacement by either taking them to a store or calling our team on 03330 112 112.
Thank you for using Q&A (CW)
