Yes, but that was the standard 5LED Duo. There's also an 8LED and a 14LED. The latter is still not the brightest lamp you could get but, as I said, it gives a perfect cone of light at just the right intensity.

I think the Duo with 14LED module is about £70 or £75. Another plus with it is the bomb-proof build quality (it's a caving lamp really). It is MUCH more robust than any other headtorch I've seen.
