YouOKLight-Portable Flood Light from GearBest- Review

Hello
I am testing for you a fully flood portable lamp,with built in rechargeable battery pack.
The lamp is suited for different indoor or outdoor use-for work,camping,emergency,domestic illumination, construction industry,property management,and other activities.
The lamp was provided by GearBest for test and review.

The YouOKLight comes in a cardboard box.

In real world work environment.

The angle of the light is quite wide.
Sufficient when using the lamp as an ambient light or for some work,that does not require a lot of light.
The beam is quite floody and does not provide high brightness at long distance.
If you are working something serious,you still may need a good headlamp.

The light coming from the LED is Cool White with some bluish tint.

 Two brightness levels- High/Low.

Comfortable handle thanks to the foam tube added. Could be a plus if you plan to carry the light for long periods of time,outdoor.
The size and form are quite good for stable grip.

The YouOKLight comes with two chargers-for indoor and outdoor charging.

Home charging adapter with output 8.4V, 1A

Car charger with output 8.4V, 1A

The main specifications can be seen on the back of the plastic housing.

The Lamp can be detached from its stand.Just have to unscrew the connecting bolt.
There are few openings allowing to mount the lamp to different stands,etc.

On the back of the lamp are mounted both switches and the charging port.
I should note the lack of any marking indicating,which switch is for On/Off and which for mode changing.
It seems easy to remember,but when you are in the dark and even on light is somehow hard to find the right switch.It is needed some time to get used with the position of the switches.
The charging port has water sealing,rubber cap.
Both switches are also protected by clear covers. The light can be used in humid or dusty environment.

Below is a Run/Time graph for High mode.
The maximum battery voltage is 8,4V. The LED is for 6V voltage.
The voltage is limited to the required level by a resistor.
The second-lower mode is also adjusted with another resistor.

Usually so wide angle beam is hard to measure with a regular integrated sphere. I tried to measure the lumen output in a cardboard box and got this numbers:
Max brightness on High mode 556 lumens
Max brightness on Low mode 152 lumens
The used LED is powered with 6,2V on High mode and 5,5V on Low mode.
Current draw on High mode I=750mA (4.65W)
Current draw on Low mode I=190mA (1.045W)

Here is the front of the lamp,disassembled.
Metal frame and thick tempered glass are mounted on the front.

Below is the back of the lamp disassembled.
There is a battery pack of four batteries,glued in the plastic housing.
They seem to be 18650 batteries, 2x2200mAh in series with another two in parallel connection.
The lamp is advertised as 4400mAh,7.4V.
I did not cut the wrapping(yet) to see their brand.

Here is a close up picture of the limiting resistors.

The front glass is protected from dust and water with a thick silicone gasket.

The big LED is mounted directly on the metal housing.There is quite enough thermal paste between them.
The whole back side of the housing is formed as cooling fins.The heat dissipation is quite good.
Two screws ensures tight press for good heat transfer. There are two more threaded holes,but without screws added.
Thick enough wires,well soldered.

The reflector is made of very thin metal.It reflects small part of the light and does not have the purpose to focus the light in small hotspot,so more special reflector is not needed.

Aootek Portable,Rechargeable Camping/Home use Lantern

Hello

I am reviewing for you a new portable LED camping lantern provided by Aootek.

The lamp has buit-in Li-ion battery,which can be charged via special charging dock station,included in the set.

The lantern is composed of yellow LED light source,which illuminates through matte,diffused plastic housing.

This ensures nice,pleasant for the eyes wide floody light,suitable for camping,reading,in-house use and many other. The yellow light is a little uncommon in flashlights and other lighting devices,but is more pleasant for the eyes compared to the cool white light,especially in the dark. I did not expected good color rendering,but after turning the light on,I found it pretty good for any use. looking directly at the lamp,the light seems quite yellow,but looking away at some distance,the light does not annoy at all. 

Brightness level can be adjusted via rotating switch,working as a potentiometer. 

The light can be adjusted infinitely,with no defined steps.

Max brightness is quite enough for most uses that come in mind. It seems about 100 lumens,but I can't measure it in my setup.The light comes from a very wide surface,that requires a special equipment.
The lowest brightness is quite low. I would like a little lower output for using in full darkness,though.

At the top of the rotating switch is added a button for another switch.It's purpose is to activate the automatic timer function,which shuts down the light after 10 minutes. It could be called a sleep timer.

A nice feature if you use the lamp as a nigh light,before sleeping.

The charger is lightweight,can be transported easily. Can be connected to main power supply.Depending on your country you have to use appropriate adapter.I use US to European adapter.

The Aootek lantern has an intelligent function for auto-starting in case of power outage.
Just keep it on the charging dock,connected to the main power supply. Once it detects that the power has shut down,the lantern will activate by itself,not leaving you in full darkness.

The lamp is lightweight as well,which is great if you like to carry it on camping.It will not add much weight to your backpack. The lantern itself(without the dock) weights just 220 grams/7.76 ounces.

There is a thick strap added on the top of the lamp.It can be used for holding the lamp,or for attaching it.

According to the specifications,the battery is Li-Ion with capacity of 1600mAh. Charging it with 500mA should take about 3 hours.But I did not measure the charging current yet,so can't confirm for now.

Here is a full run test on maximum output.
The lantern was set to max brightness and left static to measure the brightness change during the time.
This test was after the first charge of the battery,so it is possible to get a little more run time after few more times recharging. The output holds well for about 6 hours.

After using/testing the camping lamp for some time my impressions are only good.It is quite easy and convenient to use it.There is nothing confusing. As I already mentioned,the beam is  good.

There is no info about the water resistance.I assume the lantern is not sealed,so it is recommended to keep it dry. This is maybe the only thing that could be improved.

I have nothing more to require from this product.

It worked as expected,without any flaws during the test period.
