DIY Smart Lighting Guide (For Residents)

Call a light that responds to your voice, optimizing it from its placement. Installation tips and a checklist (Japanese guide)

Non-invasive smart lighting you can use even for rentals. Here, we organize—step by step—where to place it for the best detection, the placement that improves your everyday experience, and the items to check before installation.

1) First, the basics of where to position everything.

The distance where your voice can be heard. From the “daily route” of your bedroom or desk, position the light where it can be seen.
Reduce obstacles. The back of the shelf, behind the curtains, and areas in the shadow of tall furniture are more likely to cause unstable reactions.
Move closer to the center of the room. If some dark areas remain in spots, the lighting experience for a change of mood may feel less noticeable.
Ease of switch operation. Check not only how it works with your voice, but also the physical button operation flow at the same time.

The key is not “sound,” but your day-to-day field of view and where you speak from. Using lighting within the range you can see will increase satisfaction.

2) Recommended placement options by room

Living room

On the front of the sofa, or toward the center of the dining area. If the TV reflections bother you, angle it slightly outward.

At night, depth comes from looking “top-down” or “from the side”
Reading should be at a height that doesn’t obstruct your view.

Bedroom

The ideal location is where the light is visible when you reach out from the bed. We’ll also plan the route you’ll take when you wake up.

Create a “Voice → One-Tap Light-Up” before bed
Adjust the direction so strong light doesn’t hit your eyes

Kitchen & Dining

From the back of the workbench, direct the light toward your hands. If the shadows are too dark, your hands get tired.

During cooking, operate the color temperature in a “calm and leaning toward warm” setting.

Entryway & Hallway

Many people call out to you in places where you’re on the move. Prioritize a layout that reliably lights up even over short distances.

Avoid the “shadow” behind shoe boxes and shelves

3) DIY setup checklist (before installation → first power-on)

1Check the power supply and whether installation is possible

Check the type of the existing light and the method for replacing it. We’ll assess in advance whether it can be completed within the scope that tenants can handle.
2Choose where to speak

Optimize the layout so that the speaking position (by the bed, in front of the work table, or on the sofa seat) is at the shortest distance.
3Reduce obstructions around you

Avoid areas where the signal is likely to weaken, such as shadows from the back of shelves, heavy curtains, or indoor plants.
4Check “illuminance and appearance” during the first light-up

If it’s too bright, adjust the light output and color temperature settings. The same applies if the light is too strong on your eyes.
5Action Test (Morning & Night)

In both the brightness of the morning and the comfort of the night, we test the “scenes you want to use” by voice.

Common Pitfalls and How to Fix Them

It takes too long for the light to turn on even when you speak to it.

First, check whether the speaking position is visible from the light. You can often improve the result just by avoiding areas that fall into shadow or spots behind shelves.

The darker side remains more than I expected.

“Move it toward the side closer to the center of the room” and try shifting the darker direction of the shadows. Your lighting experience changes significantly with the placement.

Switch and voice control get confusing.

Grouping the physical switches in easy-to-reach positions makes voice use scenarios and switching feel more natural.
