reading further about the SK68 here at BLF I found these, supposed to be running cooler and brighter than the average (?)
either way it looks like it's hard to fault the SK68 as long as you get it from a respectable seller (whether ebay or fasttech)
my kids will be happy (I already have two Nextorch headlamps on the way for them - very little info on these but they looked good for what they were) 8-)
