A complete guide to the must-have item for idol concerts: the King Blade. Recommended models.
Penlights are mainly seen at idol concerts, and among them, some have become branded and enjoy immense popularity.
This time, thatKing Blades (light sticks used by fans at concerts)I would like to provide an explanation about it.
A penlight—an essential item for live shows
At idol concerts and the like, if the venue is large, you can still get the idol’s attention by bringing glow sticks in your favorite member’s color to show your support.

This is also a photo from a Dempagumi.inc concert. The audience area is dark and hard to see, but only the glow sticks shine, serving as the lighting—or rather the decoration—for the entire venue.
In other words, the venue is owned by the fans.Completed with a penlight in handI am doing it.
As expected, penlights are an essential part of live concerts.
Next, I will go into more detail about the glowing sticks that the fan is holding.
There are penlights that are battery-powered and ones that use chemical reactions (chemical-type penlights).
The chemical formula penlight is,glow stickalso known by the name.
Cyalume is actually a brand name, but it’s become so common that some people think “cyalume” means any chemical lightstick (penlight).
When you gently bend the stick, the glass ampoule inside breaks, causing two liquids to undergo a chemical reaction and emit light.
Because the chemical reaction ends, the luminescence also stops, so it is disposable.
Since one won’t last from the start to the end of the live show, we have to prepare several of them.
On the other hand, a battery-powered penlight can be used until it breaks—just buy it once and replace the batteries as needed!
It's environmentally friendly—eco!
Also, if it’s something that can change colors, you won’t need to carry multiple kinds, and it’s more compact.
A battery-powered penlight is not a King Blade!
Among these battery-powered penlights,The overwhelmingly popular one is the King Blade (lightstick).It is!
The same phenomenon that happens with glow sticks is also occurring with King Blades, and some people understand “King Blade” to refer to battery-powered penlights.
Actually, King Blade is,Louis Fan JapanAn abbreviation of the King Blade sold by Kara; it's a product name.It is.
King Blades (light sticks) aren’t disposable; they’re battery-powered and can be used repeatedly.
Also, because it uses AAA batteries, its output is stronger than that of button batteries.
The great thing about this King Blade is that you can change its color with a button.
In idol songs, there are many times when, for solos or certain parts, you have to use a designated color rather than your oshi’s color.
If you’re using single-color penlights, you’ll need to bring several.
However, a single King Blade is sufficient.
This can be purchased anywhere.
You can easily buy it at places like Don Quijote and LOFT.
With just two buttons, you can easily turn it on and off and perform color conversion.
Because it's simple, you can operate it easily even in dark live venues or when you suddenly realize, “Oh, the song has already started!”
And because it’s a well-known brand, it sometimes collaborates with idols.
For fans, having a limited-edition collaboration King Blade as concert merch would be insanely exciting.

You can also make a film like this to create a custom Kimbure (King Blade).
With Ruifan Japan’s technology, King Blade light sticks can be controlled wirelessly.
It is also used on television music programs and the like.
Recommended King Blade Ranking
Next, I’d like to introduce my personal recommended King Blades ranking from first to third place.
1st place
For beginners buying a penlight for the first time, I recommend this King Blade.
This light stick can switch between 15 colors, and you can set it to your favorite idol’s color.
You can also set two types of color sequences using the memory function.
You could call it a high-performance standard penlight.
2nd place
In addition to the functions of the No. 1 II King Blade, it also includes a feature that links with a smartphone to light up in original colors.
If you're becoming more particular, we recommend getting this one.
Also, if there are detailed specifications for an idol’s assigned color, this option may not produce the exact shade you have in mind.
3rd place
This one doesn’t perform color conversion; instead, it produces more vivid coloration and luminescence.
With the light level switching function, you can switch between four brightness levels.
It might be nice to have one in your favorite idol’s color.
In conclusion
Penlight entry policyThere are some sites like that.
For example, only official merchandise penlights are allowed to be brought in.
Only penlights with a total length of 25 cm or less, only button battery-powered penlights, and so on...
Before going to the site, be sure to check in advance.
Also, depending on the venue, there are places where bringing penlights isn’t a common practice to begin with.
If you’re the only one who has it when no one else does, it feels out of place, doesn’t it?
Depending on the venue, there may be rules—such as only using glow sticks during an idol’s birthday performance—so be sure to gather information carefully.
