It was Ironic that this thread started up as the day before I got a salel
notice from my Amazon Prime account. It gives me the opportunity to play David
Lockyear and do a lamp report. I've got several LED head lamps, suitable for
utility lights, setting up camp etc. I found that Amazon had a sale on
headlamps. One was a CREE 1600 lumen lamp.
http://www.amazon.com/gp/product/B0098IJC7C/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1.
I took delivery on Friday and I must say they are phenomenal for the price.
There aren't many caves that 1600 Lumen wouldn't be adequate for and those
certainly wouldn't be in Texas. The complete package include batteries,
charger and headlamp. I saw ads for the same lamp for a much higher price that
didn't include the battery and charger.
If the batteries don't last long, they are pretty inexpensive:

The battery life rating for the highest brightness isn't that great but I'm in
the process of testing how long they last with this light.
Even the low light level is pretty impressive, supposedly 100 lumens.

And I still use a carbide lamp though not often. It can be used to cook a can
of beans. But then the new world of cavers eat that dry stuff that you just add
water to and shake. No caver stews I am sure, though we ate a lot of that and
so did the Mexican dogs at Golendrinas after the basketball game between cavers
and kids. Final score Kids 40 Cavers Zero.

Not with headlamps, only as regular house incandescent/CFL lamp replacements.
We like them because they are cheap ($4 at Home Depot for the 60 W version) and
are dimmable to a certain extent. They seem well made and with luck will last
longer as lamps than I will as a human being. With power output that you
mention on the headlamps, we call them formation burners. You could topple
Goliath with one sweep of that beam light!!!

Greetings,
Anyone have any experiences with CREE headlights? Good? Bad? other wise...
It says 3000 Lumens, It cause pain when I try to look in the beam... And leaves
a streak like you have looked at a welding light ... temporary though...
It is bright and I have tested it on two 2800 mAh 3.7 v batteries for 48 hours
and there is still usable light although not as bright as it was...
