The quest to the ideal portable work light

[donkey77]

I got a nice Led Lenser headlamp as a gift from my son and while I've had a few over the years not had one as nice as this.

Comes with AAA batteries and a LiPo rechargeable.
Focusable beam and a few lighting modes that when first fiddled with you think WTF, do I have to toggle through all these each time I want to turn it off but no, after a little time in each mode just a single press turns it off. 
About time someone used their brains in multimode products ! 

I'll second ledlenser. I've got a couple of there i7r's with spare battery packs left charging in the back of the van. You can also use alkalines if needed. Keep meaning to get a head torch version too, not cheap but good, and when using it for work I don't see the issue with spending the extra £20-30 over a cheap model.

The hardest is going to find one that does not have all those annoying flashing modes you have to cycle through each time you turn it on.  I don't know why that's so popular. 

That drives me nuts, I have never been able to figure that out either, unless the Chinese take the name "flashlight" literally?

Does anyone actually use those flash modes? Ever? I have not even once on any light I've owned, it's just a nuisance.

It is used on high power lights (often called "tachlights") as stun/blind mode (self-defense). Though that's a rapid flash, if it's a slow flash then it's a warning mode (neither of which have any buisiness in a low power handheld or headlamp, meaning repurposed crap from Shenzen).
