The best off the shelf light i've seen so far has been the Hope 4 LED - not just for the product but for the customer service as well. CK picked his up for £150 s/h and as it's hope you have support at the major events - easy access to spares and superb customer service. If youre technicly minded you can't go wrong with a Troutlight for some serious power. I have a 6xpe one of his that i built up and have yet to see anything as powerfull.
