Product Review

First, let’s take a quick recap of the effects of the different colors of light on our attention spans.
As you might already know from Science class, each color of light has its own distinct wavelength.
Blue is the shortest. Red is the longest.
UV light and infrared are either too short or too long to show up on the visible spectrum.

Different colors are associated with different feelings.
Red is the color of passion and strong emotions. Yellow is a warm, bright, and optimistic color.
Orange is upbeat but not overly enthusiastic. Brown is neutral.
Green and blue calm the hyper-anxious mind. Pink is inviting.
Bright colors make you feel alert; neutral shades help you relax.
Teachers think yellow helps you solve math problems better, while pink catches your attention.

That’s one of the greatest benefits of RGB lighting.
You get to choose which colors or combinations of colors suit your mood.
Whether you’re craving for the next episode of your favorite comedy sitcom or you need to concentrate on a very important assignment, take your pick from the 15 different light modes available in the BlitzWolf BW-CML2 monitor light.

If you’re a gamer with a love for endless MMORPGs, you’ll surely want something more sophisticated than the average light bar.
So what makes the BlitzWolf BW-CML2 so special? Here’s a rundown of its top features!

Adjustable Temperature

White light consists of all the colors of the spectrum. Warm light is what you get if you strip off some of white light’s blue wavelength. Earlier we mentioned that the color blue is peaceful and calming.
However, as you may have already heard, it can also keep you up at night.
This is because blue light affects your body’s production of the sleep hormone melatonin.
Without melatonin, you’ll be awake and alert, even when you’re exhausted and really want nothing more than to fall asleep.

LEDs are more cost-efficient than other light devices, but they tend to produce more blue light.
While this is fine during the day, too much exposure after sundown can affect your sleep habits.
That’s why it’s crucial to buy a monitor light with a warm light feature if you spend long hours in front of your computer at night.

People who have a blue light filter running on their smartphones and PC monitors are already aware of this, but what’s the point of using a blue light filter on your screen when your light source isn’t blue light free?
With a temperature range of 2,700° K to 6,500°, the BlitzWolf BW-CML2 gives your three options — warm light, normal light, and a combination of the two.
The general rule is to use the warm light when gaming or watching a movie, mixed light for casual reading or surfing the web, and normal light when working during the day.

Adjustable Brightness

The BlitzWolf BW-CML2 ranges from 300 to 1,000 lumens in intensity.
You won’t always need to keep a monitor light at maximum intensity.
If you’re watching a movie, you’ll need less light than when you’re working on a spreadsheet full of decimal points.
If you’re the type who goes on gaming sprees for hours on end, it’s even more important to get the lighting right.
You wouldn’t want to lose just because your eyes got so fatigued that you couldn’t see the huge scythe aimed at your character.

Because the BlitzWolf BW-CML2 is set at an optimal angle of 25 degrees, it can illuminate your keyboard and monitor while cutting down on unwanted glare.
It’s set slightly forward so less light gets wasted.

Ease of Installation

It only takes a few easy steps to set up the BlitzWolf BW-CML2 on your monitor.
First, make sure to wipe the monitor frame and back to get rid of all the dust.
Do this step carefully; if any dust remains, the adhesive won’t stick so well.
Next, attach the adhesive part of the metal strip to the back of your monitor.
Insert the cable through the holes in the bracket and use the magnet to attach the bracket to the metal strip.
Make sure the BlitzWolf BW-CML2 light bar is positioned in the center.
Plugin the USB cable in any USB port or power bank and you should be good to go.

The only problem would be if your monitor is too thin or too thick.
The BlitzWolf BW-CML2 is only suited for screens between 15 mm and 25 mm thick. Any thicker or thinner and the bracket won’t hold up.

The right end of the light bar is touch-sensitive. Press once to turn it on. Press twice in rapid succession to turn it off.
Once it’s on, press lightly to adjust brightness, and long press to switch between warm, normal, and mixed light.
Another touch lets you choose between the BlitzWolf BW-CML2’s 15 light modes, seven of which are in a single color, seven more with RGB multicolor effects, and one automatic mode which switches seamlessly between the different modes.
