Review Olight HS2 Headlamp
« on: September 05, 2017, 03:49:35 PM »
This is the Olight HS2 Headlamp sent for review from Olight and NO other compensation other than keeping the light.

The HS2 can be found at the Olight official store …..(Links are NON Afilliated) is external)

or on the Ebay site …….. is external)

First I would like to apologize to Olight and everyone else that this review is so late. I usually try to have my reviews done and posted within a week or less of receiving the lights. There have been so many things this time to slow me down though….first the rains form Hurricane Harvey , although not in the direct path we had rain for 6 days (5 full days and half the 6th) with 14 inches total.
Then there have been several other things going on such as me trying to do what I can to help a good freind of mine that recently had a heart pump implanted and is unable to do much at all and the list just seems to go on from there.

Ok enough about my personal stuff , on to what I am here for……………

The Olight HS2 is a very small and light weight headlamp , good for jogging , hiking , close up work , camping and I am sure a number of other activities.
The power supply is a 2000 mAh Lipo battery pack that powers this little light , or the included USB charger cord can be connected directly to a powerbank , wall cube or your computer and the light ran straight from any of those without even needing the included battery pack.
The head of the light is made seperately from the power supply , or battery pack and connects through a micro USB connector. The connector is a very solid connection though and should keep out dust and water such as in a rain , at IPX4 I dont know that it would be good to submerse this one.
The battery pack itself is sealed and is charged through the port located on the end of the power supply and sealed when not in use with a rubber cover that fits snuggly into the slot. There is also a power level indicator with 4 blue lights that you can check at any time by pressing the small switch button located right next to those.
1 Light is 25% , 2 lights 50% , 3 lights 75% and all four indicate full power.

The coolest thing to me about the HS2 is that you have 2 separate LED’s and 3 separate beam types from the single head. There is a floody TIR optic , a throwy Optic on the other side and you can also turn on both beams for the max output from the HS2. Each beam has a low and a high , as does the dual beam with both LED’s turned on. To turn the light on simply click the switch , then another click will go to low mode (light always comes on in High with both beams). When you want to change to either the flood or the Throw beam only , a double click is used to go to those and a single click to change from low to high. To turn the light off a long press shuts the light off. Also the mode changes and the off / on are a very soft , almost a gradual dimming or brightening. There is also the hidden SOS mode that is accessed with 3 quick clicks of the side switch.

The HS2 can get hot when ran for extended periods , with both the emitters turned on and little to no airflow. It does seem to handle the heat pretty decent though as long as there is good airflow over the light when both led’s are used. When using either of the single led’s the light seems to me to be ok with the heat even indoors. There are small fins made on the head to aid the cooling , but none the less there is not alot of surface there and the light is very close to the headband.

When the cells are getting low the indicator lights will start blinking as an early warning. As the cells deplete more you will hear an audible alarm sounding and when the cells are almost totally depleted there is a really fast blink of the LED’s along with the audible alarm.

Overall this seems to be a very solid built little light and for the small size of the battery pack the runtimes are excellent IMO. The UI is simple , although not everyone will be happy with only low and high modes. The beams blend good and do not make any kind of weird looking separate hotpots. The one thing that I think would make this little headlamp even better would be to also produce it in a neutral tint.
Other than that I really have no negatives at all about the HS2 Headlamp.

Here are the charts for what testing I have done so far……….

For those who do not want to watch the whole video the Still shots of the light and the beamshots start at 7:14 of the time line and the outdoor live footage comparing the H1R nova starts at 10:45 of the time line.
