I have been using a 7 led cluster bulb (you can buy them from most caving shops for about £30) in my Headlite. The problem that I have is that one or more of the individual led's have failed. I have 8 lamps that I use for work, so when one fails I take a bulb out of another lamp. I now have five duff bulbs out of my original 9. Can anyone tell me why they are failing. Some have failed completely, while others work, but at a much reduced brightness. Also can you tell me who makes them so I can send them back. The shop I bought them from (Quipu in Bristol) are no longer in business, so I need to return them to the maker.
