Nitecore NU25 headlamp

The Nitecore NU25- a quick mod

Three Points of the Compass has used a few headlamps  on trail over the years. The one that is currently in favour is the Nitecore NU25. Available in black, yellow or white, I have the bright yellow lamp. All the better for being found as light fades.

It is a great headlamp. It has a built in 610 mAh rechargeable Li-ion battery. Separate buttons for white or red light and has decent Cree XP-G2 S3 LED fitted.

Weather resistance is fairly good at IP66, this is helped by a flippable rubber covering to the micro-USB charge port. Beside  the two intensities of red light, there are varying white light, maxing out at 360 lumen. More stats can be seen here.

All that said, there is one big fault with the light. The headband is total overkill for such a lightweight headlamp. The light weighs 28g. the headband a further 25g. There is a quite well known modification that replaces the, admittedly very good, headband with a simpler set-up. For any that are unaware of this, I show it here.

The headlamp will tilt up to 60° from the curved head support. This aids its correct alignment when night walking, or when simply sitting on the tent floor at night. The headband simply slips out of the rear of this folding head support. This shows that it is made up of a number of small holes, just right for slipping thin shock cord or bungee through.

A few minutes on eBay located a number of sellers of both shockcord and cord locks. Just a few quid secured 10m of 2mm cord (more than I am ever likely to require), plus a wee baggie of double cord locks. Each of these weighs just 1.2g. Together with a pair of scissors and a lighter, is all that is required for the modification.

I looped two lengths of 2mm shockcord through the rear matrix. You can see how in the associated image. One running through the top, the other through the bottom. The bottom cord was then tied back on to the top cord with a running slip knot. Then trimmed and ends closed with a lighter. The top cord is long enough to pass behind my head with a little extra for adjustment if required to be worn over a beenie or similar. I ran the two ends through the toggle and tied them off together, trimmed the ends and sealed with the lighter again.

The whole job took less than five minutes to complete. The modified lamp with replacement head cord, now weighs 34g. So has knocked off 19g with no loss in function. It is less bulky, is comfortable to wear, doesn’t slip and is adjustable. A win win…
