Sipik SK68-3W quite a surprise.
It's bright with a normal AA cell but brighter if you use a lithium 14500 cell.
I'm a bit slow and rundown ATM but since I'm not actually ill I have to wonder if I'll get some energy back again. It may be my diet but I can't help but link it in my mind to those dreadful statin drugs Lipitor and Crestor that I took years ago. On the plus side Lipitor is quite good at reducing hair and thus making haircuts much easier but the other side effects just don't make it worthwhile for that. BTW if you're a woman with thinning hair and you take Lipitor you've quite likely found the reason.
