To answer your question, we understand that your cans are not equipped with holes to fit our clips into. Going forward we had another customer who called in with the same problem, he told us that he used silicon to have his light stick to the ceiling.
He really liked the product and didn’t want to return them because his cans were incompatible. You are more than welcome to try this method, given the fact that the lights are LED’s and they should sit there untouched for 10-20 years.
If you are not comfortable with this method you can always have the product returned for a refund.
If you have any further questions please do not hesitate to contact us at 1-877-333-0098 or by email at firstname.lastname@example.org
Thank you ,
