The led’s don’t look replaceable. There are two rows of led’s surrounding the magnifying glass one cold and one warm - you can adjust the rows independently to create a warmer or cooler (bright white) light. I think it’s quite ok for the price. Aside, take note of the dimensions, it’s quite big and more suited to a large desk.

I'd say at least 1,000 headlights! :-)

Incorrect. There is one 5-Star review from a customer that has ordered the product last month. As he has written no text in his review, it doesn't show up under "reviews" and is just shown in the stars section below. Not everything is a conspiracy.

According to the manufacturer, the diameter of the lens is: Diameter Lens 127 mm.
