First it's not a headlight. It's too short. Should be at least half an inch larger. Bought it to have natural light in the kitchen. I did not expect such a low durability of the product. There is another problem with this lamp - it stays too deep in the recessed housing, which in turn acts more like a spotlight. But there's good news - they'll all be gone in a short while, so I can replace them with something else. In fact it was a waste of money. Beware.
