Oh, if you need some extra horsepower and don't mind the form factor: https://www.blackdiamondequipment.co...-700-headlamp/
Also looks like the Storm 400 will be phased out for the 450 some time soon. The 500R is already out, if you prefer a sealed rechargeable instead, though for my uses, I would much rather have the ability to swap batteries on the fly as needed.
I've never had a BD headlamp, but I'll probably pick some up next month when I make an order on some other BD stuff.
