Headlamp Buyer’s Guide Extras
The Technology of Headlamps
Headlamps have changed a lot since the early 1980’s when Ferdnand Petzl was making tungsten headlamps for climbing.
How to Decide Which Headlamp is Best for You?
The best way to figure out which headlamp you need as you look to purchase in 2020, is to reverse engineer it. First – figure out what activities you’ll need your light for. Camping? Non-technical trail running? Road running? Skiing? Mountain biking? Spelunking?
Some people need light for many varied uses, and there might not be a headlamp that does EVERYTHING. Which criteria are you willing to compromise on? Battery life is probably a good compromise because you can always buy more batteries.
It can get expensive, but if you find a headlamp that does everything you need, but the battery life isn’t up to par – you should probably just bite the bullet and grab an extra battery too.
Beam Type – Quality and Shape of Light
What kind of beams will you need – and how bright – will be the next questions. If you’re hunting, you’ll want a strong center spotlight beam like provided on the Fenix HL60R. If you will be reading at night in your tent, or want a tent light, you can be fine with the Petzl Actik Core, MYO, or Black Diamond Icon.
The Petzl Nao series is best for runners and those who want a light unit with bright light for a long time – hours. If you’re exploring caves, you probably want a NAO+ or DUO S – or two of them to give you redundancy so you’re not stuck without light at some point. If you want a headlamp to strap on your bike occasionally, the Ultra Rush is great for that.
What About the Shape of the Light Pattern?
You may not have even thought about it yet, but the shape of the light cast is one major factor that you’ll need to take into account when choosing your headlamp. The shape you want depends on the activity you’re doing.
For looking for wildlife in the rainforest and on the road, the Nao series or the Ultra Rush works perfectly for me. The beam is bright in the center and gradually gets lighter on the sides. The beams have a nice width to them. Recently we found the OLIGHT H2R NOVA – it has a nice beam that is a combination of flood and spot – and it’s ideal for most activities.
Do you need very long battery life, and are you willing to sacrifice a light pattern with a constant brightness level? The Reactive Lighting Technology by Petzl was created to save battery and provide great lighting when you need it. Petzl has definitely succeeded – and their lights with RLT are definitely some of the best on the market. Personally, we feel they are the gold standard by which we judge other headlamps. RLT is not a gimmick, it works for most activities.
Two Headlamps with Reactive Lighting Technology:
Batteries – Many Options
If you’re going on an extended trek across mountains in Nepal or the Rockies, you’ll want to have either an excellent solar charger to charge your batteries, or you’ll want to stock up on AA or AAA batteries to provide you ample light over that long time-frame. Here are the battery options for the top headlamps listed above:
- OLight H2R NOVA – uses a custom 3000 mAh lithium-ion 18650 battery. Cheap $20 replacements. Highly recommended in every category.
- Petzl NAO+ Plus– One proprietary rechargeable lithium-ion 18650 battery. Programmable battery life with the smartphone app. Can get maximum brightness or type of beam for any activity. Quite amazing.
- Petzl Ultra Rush – One proprietary ACCU 2 rechargeable lithium-ion battery pack with two 2600 mAh 18650 batteries. Can also upgrade to ACCU 4 for twice the battery life.
- Fenix HL60R – One Fenix 18650 rechargeable battery, or two CR123A store-bought batteries.
- Petzl ACTIK CORE – One CORE 1250 mAh battery, hybrid – can also use AAA batteries.
Headlamps are not really made for underwater use, though of course there are diving lights that can be used for that purpose. Headlamps maximum water resistance is at a depth of around 2 meters for 30 minutes. Any of the headlamps above will do well in the hard rain. Here are the ratings…
- OLight H2R NOVA – IP 8 (IP X8) – severe weather, and submersion for a long time.
- Petzl DUO S – IP 67 – very waterproof, submersible, and shock-proof.
- Petzl NAO+ Plus– IP X4. One proprietary rechargeable lithium-ion 18650 battery.
- Petzl Ultra Rush and Black Diamond Icon – IP 67. One meter deep for 30 minutes.
- Fenix HL60R – IP 8. Two meters deep for 30 minutes.
