The fluorescent lights set in the bedroom have been replaced with Panasonic's Paluk LED ceiling light "THE SOUND HH-CF0804A" equipped with Bluetooth stereo speakers.
Other rooms have also been replaced with LED lighting, and all rooms have been converted to LEDs.
THE SOUND HH-CF0804A I purchased it from Yamada Denki Tecc LIFE SELECT Shonan Hiratsuka store and requested replacement work.
In addition, fluorescent lights installed in the kitchen arePaluk LED Ceiling Light HH-CK0622CDSimilar replacement work was carried out for (no color adjustment switching function).
In addition, lighting for the old Japanese-style room can be purchased online via Kakaku.com. Paluk LED Ceiling Light HH-CK0823CAI replaced it with a color-adjusting function.
Furthermore, the manufacturer's discount does not work, so I decided to purchase THE SOUND HH-CF0804A at a high price (59,400 yen including tax) 🤦♀️
The lighting of previously installed fluorescent lights was an old type fixed to the wall and did not have a hook rosette, so electrical work was required.
Fortunately, YAMADA's construction costs were cheaper than I expected, and when I exchanged it for two apartment-type apartments, the "Full Hook Roset" (2,750 yen), the total construction costs were 9,900 yen.
The following articles will provide details about the Panasonic LED ceiling light "THE SOUND" as well as other LED lighting that have already been installed.

Installing THE SOUND HH-CF0804A
We have carried out replacement work with the Paluk LED ceiling light "THE SOUND HH-CF0804A" using the fluorescent light shown in the gallery shown in the marked gallery.
Since there is no wallpaper attached to the back of the fluorescent light, we planned to cover that area by installing as large an LED light as possible, but unfortunately we were unable to cover everything.
So, later, I decided to remove the ceiling light and apply the ceiling wallpaper as shown below.
Ceiling wallpaper
Prior to pasting the ceiling wallpaper, I purchased the "Asahi Pen Wallpaper Grain Type Wallet Paper Paste Set" (1,564 yen) and "Wallpaper Shop Honpo Wallpaper Grain-based Thick Ceiling Woven-style White (92cmx1m)" (499 yen) shown in the gallery below.
I couldn't find the same pattern as the wallpaper on the ceiling currently on top, so I chose the same white wallpaper as possible. After peeling off the previous wallpaper, I cut the wallpaper into the required size and shape, and used the "Wave Paper Sticker Set."
When I tried to apply it, it seems that the difference in color and pattern from existing wallpaper, including fading due to sunlight and other factors. If you're interested, you'll have to ask a renovation company to repaint all the wallpaper on the ceiling, but I would like to make it OK if it's this much.
Incidentally, when I asked a contractor to replace the ceiling cloth for a 6 tatami mat Western-style room, the construction cost was 24,000 yen.
(To enter the ceiling hole, fill the wall with a hole putty to repair it, and cut out any deterioration of the wall's outer periphery.)
Example of operation of THE SOUND HH-CF0804A
Below we will explain in detail the features of THE SOUND HH-CF0804A, such as lighting, remote control operation, and Bluetooth stereo sound output.
Various lighting modes
The remote control transmitter of THE SOUND HH-CF0804A (HK9804/3CH) allows you to control various settings (time, transmission channel, good night, and Rusuban), as well as lighting, turning off, color adjustment, light and dark, leaving it to you, brightness increase, night light, and hand light.
The buttons inside these will light up green in the darkroom.
The "Light Up" button is 6200K (unit: Kelvin) and is 130% brightness (34.8W) when fully lighted. Although color adjustment operations are not possible in this mode, they look very bright and clear, so they can be used for a variety of purposes, such as sewing and makeup, which require detailed work.
The gallery below includes scenes for remote control transmitters and various lighting modes.
Sound playback over Bluetooth connection
The stereo speakers of THE SOUND HH-CF0804A come in two ways: plug the audio connection cable of the wireless transmitter (HK8900) into the TV's audio output terminal (3-pole 3.5 mm mini jack), press the "Bluetooth button" for more than 5 seconds to connect it to a pair, or connect it via Bluetooth from a smartphone or PC, and play music from an app.
In particular, by switching the audio output of the TV to the output from THE SOUND HH-CF0804A, you can enjoy high-quality, realistic sound that shines down from the ceiling.
Pair the wall switch and within 2 minutes. However, since this speaker does not support multipoint connections, it is not possible to connect a TV and a smartphone at the same time. In addition, there is no dedicated app (equalizer, etc.) to adjust the sound quality, and it does not support LDAC codecs.
As for wireless transmitters, once pairing is performed, all you have to do is turn on the wall switch and the pairing will automatically be paired.
Furthermore, since the HH-CF0804A has a stereo speaker L/R, when installing it, it is rotated to adjust the orientation of the unit, taking into account the viewer's position.

bathroom LED lights
I replaced the incandescent bulb (E26 base) in the bathroom with an LED bulb. Although it is a waste of money, after trying out three types of light colors: daylight, daylight white, and light bulb colors, I decided that the best bathroom is "daylight white." *
The reason for this is that the daylight color is too bright and dazzling, and the light bulb color is too dark to be difficult to see, so I chose the daylight color, which has a Kelvin value (color temperature) in between.
*P.S. Purchase of two packages was a waste of money 😥
Toilet LED light
I replaced the toilet ball bulb (E26 base) with an LED bulb. The light bulb colour was perfect here.

Replace the fluorescent light installed in the system kitchen with an LED light
The fluorescent light installed in the system kitchen has been replaced with a 15-inch straight tube LED light (first image in the gallery below). This type of LED light must have the glow removed prior to replacing it.
If you replace it with a straight tube LED light, you will no longer need a ballast. Since ballasts consume a certain amount of power, if you replace them with LED lights, it is best to also perform removal work on the ballast.
This fluorescent light will have the wiring as shown in the title "One-Coil Electric Circuit Configuration Diagram."
Therefore, you can disable the ballast by cutting the white and black wires soldered to the single-light glow fluorescent bulb (starter type) ballast (FL15) using a nipper and shorting (soldering or connecting the connector) these two cables.
Furthermore, if the above electrical work is carried out by someone who does not have a license for a Class 2 Electrician, it will be a violation of the law. I specialize in information at university, but I graduated from the electrical department of a technical high school and took all the subjects required to obtain a Class 2 Electrician license, so I would have easily gotten my license if I had taken the exam, but now I regret not getting it. I had an unwanted license for a dangerous material handler (Class C) but when I moved, that license disappeared lol

In the end, the work mentioned above was carried out as follows and the ballast was disabled. The short circuit for the white and black cables is the "CTRICALVER Compact Wire Connector" (rated voltage: 600V / rated current: 32A) purchased from Amazon.
