We have a range of these for our band, some of the desk light style ones, and quite a few of these double headed ones. These are the best ones we have of the double headers, and we find them the best for general use - the desk light style ones are too big.
But we did find some very cheap ones on ebay that are not as good, but work perfectly well, but as we are a large band, we have more of them.
I found the item to be convenient, easy to pack away and 'a must have' for reading music where room/stage lighting is inadequate My advice would be, though, to make sure that the 'light spread' of this item is sufficient for your purposes (check this out first before purchasing !)
