Reading about all the great headlamps has just about got me talked into getting a Zebralight. I have NiteIze flashlight holder headbands that work well but I'm thinking that the Zebralight would be better as it's much easier to adjust the beam and I like the idea that it's in the center of my forehead.

Very nice summary of issues when making a purchase.
One point I'd add is that I'd feel very uncomfortable about strapping lithium batteries, especially multiple 18650s, to my head. It makes me shudder when I see lights on ebay claiming to drive XM-Ls at 3+A from Ultrafire 18650 cells sealed in a container and strapped to the back of the victims head. Not an issue for most sane headlamps, but likely that some will search ebay and go "OMG teh 1800 Lumenzz!!" without considering safety.

No worries as long as their protected, right? It's only unprotected cells you have to worry about as far as I know. I only by protected betteries1

You need to be cautious and monitor all Li-Ion cells, protected or not.

I read a longish post in the battery section about how protected Li-Ions have their own set of problems. Zebralight recommended unprotected for their H60. So Bill's correct, you have to remain alert around powerful Li-Ions, protected or unprotected. There's lots of discussion about the safety of Li-Ion in the battery sub-forum so I'd refer you there.
All the same, a note re: Li-Ions added to the battery paragraph, thanks for the reminder.

I assume this is for white light?
You have a link for this? If a factor of 4 gives you twice as bright it implies perceived intensity = sqrt of actual intensity, SQRT(4) = 2, over some intensity range.

This is what happens when you don't make footnotes--someone always wants the references! They're here, somewhere, on CPF. Here's one thread. And a second. A third. A fourth. Still haven't found the one I was reading while writing the above.

Bolster, is there any reason why your threads don't mention headlamps with 18650's?
I just ordered a Zb H600.
I wanted more lumens than a Spark.
The Spark SD6 seemed too floody?
Plus, the H600 was only 39 grams; the lightest of the lot.
However, you don't like 18650's?
Also, do you know of a good headlamp with a spot beam for a surgeon?
Anything apart from a HP11?

Hi Peter. 18650 is mentioned under #2, battery selection. This decision list is aimed at people new to headlamps, and the rechargeable li-ions are enthusiast's power sources. More power to you if you want to go 18650.

I though IP stood for ingress protection?
A very well written piece that just makes me want more lights!!!

I searched around...you're right! IP can stand for either, so modified. Thanks!

I think it will be great if a knowledgeable someone can update these "Threads of Interest" since the technology race changed the markets since five (5) years ago.

I think USB-recharging will play a greater role to newcomers in the future. There are some USB-rechargeable lights on the market now and this greatly decreases the impact of having a particular battery type.
Lots of newbs dont want to buy an extra charger to use 18650s but would do if the light was usb rechargeable.
