This product was not the one I was looking for and I didn’t return it as I thought this was my mistake and that of the person who thought he had given me the correct bulbs. It thought it wasn’t worth paying to return as the cost for purchase and delivery was near $20, already of no use.
Fortunately the man who suggested your bulbs also suggested the “right” bulbs and send me 10 so that $20 wasn’t wasted. I would return the untouched pair of incorrect bulbs if you want these and if you pay the post. Please let me know.
