Edna 2 Features

Filthy Edna 2

Custom designed circuitry with 2 LEDs. Reliable, versatile 3.7v architecture, now very much the obvious approach for caving lights.

 

Visible circuitry enabling easy access and cost effective replacement if ever necessary. No hidden electronics. No off the shelf drivers with clumsy compromised software.

Easy operation water resilient push switch behind robust sealed silicone cover.  Low profile, very much in keeping with the compact light weight design of Edna 2, and non magnetic obviously!

 

The easy action switch responds to a short push to switch between settings, and a long push (push and hold down) to turn off from any setting. Super easy.

Latest high power Cree XP-L2 5000k LED, with forward bias wide angle flood LED, providing an excellent field of vision, ideal for progression underground. Cree XP-L2 5000k v6 (record efficiency up to 200 lumens/watt).

 

Avoids losses of light output within lamp body from a bare LED, providing better comparable performance than lamps using bare LED. Reduces glare from a bare emitter annoying the living crap out of others. 

Effective heat sinking! Although less significant than a few years ago, due to step improvements in LED technology, heat sinking and thermal management is still an important aspect of any high output light.

Separate 'camp' LED providing 200+ hours light, at around 5 lumen light output. Great for underground camping, small grovelling passage or long prusiks!

 

Also used to indicate battery charge level. On exiting camp setting, LED with blink 1 to 5 times on the back of your hand. The original Little Monkey system, avoiding removal of helmet to count battery indicator LEDs.

Lightweight, alloy lamp bracket for solid caving proof helmet attachment. The proven, no nonsense solution. No headbands, no push bike mounts, and no Go-pro mounts or other solutions that compromise the purpose of Edna 2 as a caving light.


Edna sits very close to front profile of helmet, and compact size allows lamp to sit a decent distance above front lip of helmet to avoid light pollution in eye line!

Edna 2 attached with 'long' cap head bolts into lamp body, tightened using same allen key as battery box lid.

 

Washers (spring and plain) should be orientated as shown in photo.

Edna 2 uses a single widely available unprotected 18650 battery. Edna battery box uses battery holder with integrated li-ion protection circuitry. Batteries are readily interchangeable, for extended underground trips, and can obviously be readily replaced in the long term with new cells.

 

Battery box can also accomodate 1S1P 18650 battery pack. For more information see Edna 2 Batteries
