OLight H25 + H35 Wave Headlamp Review (New Gear)

[Page Updated: 1 June 2022]


NOTE – before we get started… the OLight H25 is very hard to find anywhere online. OLight has a habit of making good or great headlamps and immediately discontinuing them. This is a poor business decision because now we’re not going to buy or review anymore OLight headlamps until they snap out of it and make good decisions.

Instead of this OLight headlamp, I strongly recommend any of the following:

Or, read about the OLIGHT H25 below.

A friend brought one of these OLight H25 Wave headlamps with him from the Netherlands yesterday and I told him I had to review it. Why? It’s bright! It was almost as bright as my Petzl Ultra Rush headlamp, but the light beam is spread out over more area. In actuality, it’s supposed to be putting out 40 more lumens than the Petzl.

I used this headlamp for an hour last night just after I used my preferred light, the Petzl mentioned above. The OLight has a warmer beam output than the Petzl’s ultra-white beam. The OLight beam is a floodlight, versus the more spotlight shape of the Petzl. Either would be good for running, but I prefer the Petzl for looking for wildlife at night, but still, the OLight has it’s advantages – starting with the price around 40% of a Petzl Ultra Rush headlamp. That’s HUGE.

The specs say the OLight will crank out 800 lumens for 5 hours. That’s also a major benefit because the regular ACCU 2 battery on the Petzl will only output 760 lumens for about 2 hours. With the larger ($199) ACCU 4 battery, you can get 4 hours of 760 lumens. If the OLight actually can put out that kind of light brightness for 5 hours, that’s remarkable.

The price difference is substantial. OLight – $120-150 USD. Petzl with ACCU 4 battery – $629. So, you can buy 4 or 5 OLights for one Petzl Ultra Rush. That’s impossible to ignore, and most people would buy the OLight based on this fact alone.

The H25 Wave headlamp is small with a large belt-worn lithium-ion battery pack. It can produce blinding 800 lumens light for 5 hours with the highly efficient Cree XM-L2 LED and high capacity 5200 mAh rechargeable battery worn on the waist and attached to a power cable.

One of the unique features about the OLight is that it has an instant off feature where you just swipe your hand in front of it, and the light turns off – allowing you to talk in close quarters with someone without blinding them with your headlamp. The built-in infrared sensor takes care of that. Swipe again and the light is back on.


“I used this headlamp for over a year. I have always used OLIGHT headlamps for the past 8 years. I live in the Netherlands, but I order online from the USA. The light is tough and rugged. I put it through the paces. This headlamp I refined with another battery even bigger and I get 7.5 hours at 800 lumens. Best light from OLIGHT so far. I will keep buying their products. Very satisfied.” – Vince V.


A heavy-duty headlamp with the company headquartered in Georgia and headlamps outsourced to China. OLIGHT headlamps are tough, and have a couple of interesting features that other companies don’t have – USB charging for your other electronics; and, instantly shut off by waving your hand close to the beam.

Oh, and VERY good prices!

OLIGHT H25 Wave headlamp and battery unit (5200 mAh). USA product.
One bright CREE bulb with 3-levels of brightness adjustment. The infrared sensor shuts headlamp off with a wave of the hand. Wave again to turn it on.


Nice lightweight with the battery on the waist or in a backpack or waist pack. This much battery needs to be somewhere other than your head because it’s heavy – about a pound. Nice design and made with high-quality plastics and metal. The cables look strong. It really looks like a well-made headlamp.


Hard plastics. Thick rubber for the cables. No rough spots. It’s really quite well designed. The strap is comfortable and the headlamp can be worn for hours without discomfort.


IPX 6. Hard jet-streams of water. Any rain. Probably submersible for up to a minute. Can drop this unit from 1 meter high onto hard ground.


5200 mAh rechargeable lithium-ion battery. External waist-clip and long power wire goes to head from the battery.


About 1-meter diameter at 3 meters distance. Pretty ideal for most tasks. When set to high, this headlamp lights up a large area in front of you – it has an amazing flood beam that spreads out the light to hit more areas than the Petzl Ultra Rush.



Ultra Running – this is the best headlamp for this sport. The wide beam profile (shape) is perfect for running where you need to see a large area in front of you.

Cave Explorationspelunkingcave exploring. Because the flood beam is bright and spread out, you have the best of both worlds in the H25 Wave for exploring caves. Long battery life and excellent brightness and color balance. Highly recommended for caving.

General All-purpose Headlamp. Camping, fishing, hiking, working on your vehicle… this headlamp is great for all basic uses, and you have almost endless battery life.

If I was going to compare this headlamp to any other, it would be a good comparison to the Petzl Ultra Rush. The OLIGHT H25 Wave is MUCH cheaper, a fraction of the price of the Ultra Rush. The OLIGHT H25 Wave strongest light beam is more flood-beam than spot, which is ideal for caving or running – even more so than the Petzl Ultra Rush.

PRICE – OLIGHT HP25 Wave destroys the Petzl Ultra Rush in Price – that is true!

BEAM SHAPE – OLIGHT HP25 has a wide flood beam at maximum brightness. The Ultra Rush has a more center-focused beam. Each is better for some activities than others.

ACTIVITIES OLIGHT H25 Wave is BEST FOR: Caving, slow ultrarunning.

ACTIVITIES PETZL Ultra Rush is BEST FOR: Skiing, mountain biking, fast running through trails.

BOTH Ultra Rush and OLIGHT H25 Wave are great for Camping, fishing, running, slow cycling, hiking, working outside.


I’ll rate the light myself below, and then add some other ratings I find online as well.

Headlamps101 Ratings

***** – 5 Stars. I think the OLIGHT H25 Wave is an awesome light that competes directly with some of the other best headlamps in the world made by Petzl. Yes, OLIGHT has outsourced their manufacturing to China – but the headlamps are made very well and have high durability and reliability. Similar to the Fenix brand, but better. We will be reviewing a number of other OLIGHT models this year to add some to the top 12 list! We should have that list finished in March 2018.
