Finally got a paypal refund after sending back the item.
Still down return postage though.
Also got a questionnaire from the original courier asking for details of packing etc. to support a damage in transit claim !!
Wonder what to do with it ??
Try a 5 or 8mm T1 in that case. (measure the width)
Still looks more like a bulb than an LED.
what colour do you need and what colour is it in the first place.
