Configuring the Nora light settings the easy way!! No more fiddling with the lamp switch to set up preferred light levels. Just use the remote controller supplied with lamp, with feedback from the 5 green indicator LEDs. 

 

To program, use the numerical keys on remote control to select the number of light settings required, and the up and down / side to side arrows to select the level of spot and flood for each. So simple a Little Monkey could do it .... almost.

Caver firendly, easy to operate, sealed switch in protected position on back of lamp. Super robust, proven design as used on Edna 2. Low profile, very much in keeping with the compact, lightweight design of Nora 4. Non magnetic obviously. A joy to use, and no need for a travel lock.

 

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

Custom designed Nora 4 (nor4) light engine, featuring pair of advanced 'dual range' LED drivers, providing enhanced fine current control over the wide range of outputs demanded by highest specification caving light. Stable light output, equally as effective at both high and very low outputs.

 

Optimised for single or multiple parallel cell arrangements at nominal 3.7v. Now very much the obvious approach for caving lamp design given recent advances in LED technology.

Lightweight alloy lamp bracket for solid caving proof fixing to helmet, with 'long' cap head bolts into lamp body. The proven, no nonsense solution. No headbands, no push bike mounts, and no Go-pro mounts or other solutions that compromise the Nora 4 as a caving light.

 

Nora sits close to front profile of helmet, and compact size allows lamp to be mounted a decent distance above front lip of helmet to avoid potential light pollution in eye line!

New to Nora 4, hi-intensity Cree XP-L2 with smooth focus spot optic, maximising light throw from compact lamp form, while not being too narrow. Useful for route finding etc.     

Accessible circuitry enabling relatively simple, cost effective replacement, should this ever be required. No hidden electronics, and no off the shelf drivers with clumsy software!

Forward metal core mounting, positioning the wide angle flood LED as close as possible behind lamp front window. 

 

Featuring Cree XP-L2 v6 LED 5000k (record efficiency up to 200 lumens/watt). 'Moon' setting is provided by the flood LED, offering 200+ hours at maximum 5 lumen light output. Great for underground camp or small grovelling passage.

5 green smd indicator LEDs used to display battery charge level, and to facilitate user configuration of lamp settings with Nora remote control programmer. 

 

On exiting camp setting, main LED with also blink 1 to 5 times on the back of your hand. The original Little Monkey system, avoiding removal of helmet to count battery the indicator LEDs!

 

 

Available with Edna battery box or Nora battery box which can accommodate unprotected 18650 li-ion batteries and / or non-proprietary 1s2p li-ion battery packs. Batteries are readily interchangeable, for extended underground trips.

 

 

 

 

 

 

 

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. The efficiency of LEDs reduces when operating at increased temperature, and also at high output, i.e. they will be less bright per watt of energy used. Even if the battery arrangements used could deliver sufficient power to achieve some of the very high outputs often claimed, it doesn't make this good practice. A well designed lamp such as the Nora 4 will have considered this, and will operate at realistic achievable levels that protect the longevity of the LEDs.
