I forgot to add, these are the same LEDs as found in the now popular Fenix HP20
headlamp that retails for around $100 (current Amazon.com price). The Fenix is
a relatively new Chinese-made headlamp that includes an external (not helmet
mounted) battery case only. I have no idea how durable these lights are for
caving (or whether they will last for years), but I will attest to the
durability of the Duo, which was designed specifically for caving. I lubricate
the gaskets with silicone grease and I have never had water inside the battery
case or bulb case, and I have used mine under water on multiple caving trips
for over 5 years now.

> These modules use Cree XPG LEDs (your choice of the R5 or R4), and you have a
> choice of replacing just the side spot (the halogen bulb) or both the side
> spot and the original LED module. Lumen ratings range from 110 to 280
> depending upon configuration. Prices range from 28 to 44 English pounds ($45
> - 71), international shipping is free (for now). Payment is via PayPal.

> This may be an inexpensive way to upgrade your old Petzl Duo headlamp into
> something much brighter (and a lot sturdier and more waterproof) than many of
> the Princeton Tec headlamps currently available (such as the notoriously
> finicky Apex).
