Good product, good price, delivered promptly.
I was surprised at what good value these halogen bulbs are, and they arrived promptly for free at my local Amazon locker. The bulb was easy to fit and the brightness was as expected as it was a straight replacement for the old bulb which had an equivalent wattage.

Worked Fine
The bulb worked ok but the ceramic end caps that house the electrical contacts were not in line will the bulb itself making them a bit difficult to fit.
