G4 12V Dimmable White LED Corn Bulb - Smart Tuya WiFi Controlled by App and Voice

Forget the usual light bulbs: the Tuya Smart WiFi G4 12V LED Corn CCT Dimmable Bulb is the easiest way to transform a light point into truly “customized” lighting. Thanks to the compact yet powerful LED Corn format, you get uniform 360° light and a bright output, perfect for enhancing lamps, wall lamps and chandeliers with a G4 12V (AC/DC) socket. It connects to the 2.4GHz WiFi network and can be managed in just a few minutes via the free Tuya Smart or Smart Life apps: from here you can control on/off, intensity and color temperature directly from your smartphone, wherever you are. With a touch you can change the atmosphere whenever you want: choose a warm and relaxing white or a colder and more concentrated white, adjusting the CCT color temperature 2700K–6500K . And if you want the “right” light at all times, you also have 1–100% dimming : from a soft light for the evening to full brightness when you need more visibility. Want total convenience? Set timers and schedules to turn on and off automatically, create ready-made scenarios (e.g., Night, Reading, Relaxing, Work), and manage multiple bulbs together with group control : just one action and you can control the entire room. Plus, you can integrate the bulb with your smart ecosystem and even use voice control with Alexa and Google Assistant to turn it on, off, or dim it without lifting a finger. Rated lifespan: up to 30,000 hours (varies based on usage, ventilation, and 12V power supply stability).

Turn on, off and dim the lights with a phrase

Transform your lights into a truly convenient experience: with voice control, you can manage your lighting without touching switches or your smartphone. Simply say “Alexa, turn on the lights” or “Hey Google, dim to 30%” to turn on/off , dim , and set the light based on the moment. Perfect when your hands are full, when you come home, or want to instantly set the right mood on the couch: just speak and the bulb does the work . Compatible with Amazon Alexa and Google Assistant (and smart integrations like SmartThings , depending on your setup).

Timers, schedules and automatic scenarios

Set timers and routines to automatically turn the bulb on and off, even when you're away: for example, turn it on at sunset , turn it off at midnight , or have the light gradually dim as you wake up . In addition to schedules, you can use preset scenes (e.g., Relax, Read, Night) to change the atmosphere with a tap. Plus, since it's Tuya , you can create automations with other smart devices : for example, with a presence/motion sensor , the light turns on when you enter and turns off after X minutes of inactivity; with a door sensor, you can activate the light when you open the door; with light sensors, you can automatically adjust the brightness and color temperature based on the environment. A simple way to achieve comfort and energy savings without having to think about it.

Always the “right” light, at all times

With the Tuya Smart Corn LED bulb (G4 12V) , you can precisely adjust your lighting without compromise: choose a warm, relaxing light (2700K) when you want a mood, or switch to a cooler, brighter light (up to 6500K) when you need greater visibility and concentration. Furthermore, the continuous 0–100% dimming allows you to set the perfect intensity: from a soft light for quiet evenings to full illumination for more practical tasks. The result is personalized, comfortable, and modern lighting that enhances the environment and makes every space more comfortable.

Truer colors, more pleasant light

Not all light bulbs illuminate “the same way”: with a high CRI (80+) , colors appear more faithful and natural , without that dull or grayish effect typical of low color rendering lights. The result is immediately noticeable on everything that really matters: more inviting food , more realistic fabrics and furnishings , more balanced skin and shades . In practice, it is a light that is less tiring and makes the environment more “premium”, because what you see is closer to how it should appear in natural light. Perfect when you want clean, quality lighting to better experience every space, not just to “provide light”.

Adjust brightness and control from the app

G4 Corn LED bulbs have a “fuller” body than classic halogen bulbs: to avoid incompatibilities, always check the space available in the lamp holder/ceiling light (especially in spotlights, narrow wall lamps or chandeliers with small glass). Compact version (4W) : Ø18 × H63 mm – pin spacing 4 mm. Large version (4.5W) : Ø26 × H50 mm – pin spacing 4 mm. In short: a G4 fitting is correct , but it is essential that the lamp physically fits in your fixture (diameter and length). If you are replacing a “slim” halogen bulb, first check the depth and opening of the diffuser/cap.

Device Sharing & Group Control

Managing your lights becomes truly simple when you can share control with your family: partners, family, or roommates can use the same bulb without "passing" accounts or complicated settings. Everyone has their own access, and everyone can intervene when needed, conveniently and immediately. Plus, with group control, you can organize your bulbs by room or area (e.g., living room, bedroom, hallway) and control them all together with a single gesture : on/off, brightness, and color temperature synchronize instantly. The result? Less wasted time, more order, and truly convenient smart management, especially when you have multiple light points in your home.

Flicker-free light: more comfortable for your eyes

Unlike many cheap bulbs that flicker and strain your eyes, this version is designed to offer stable, uniform light. The result is especially noticeable in the evening or when you spend a long time in the same room: less eye strain , more comfort, and a cleaner feeling of lighting. It's also ideal for those who frequently use their smartphone for photos and videos: the continuous light helps reduce banding and perceptible flickering.

Where to use it: Perfect for 12V G4 light points

This dimmable G4 12V LED Corn CCT Smart bulb is ideal for modernizing your low-voltage lighting without replacing existing fixtures or transformers. Its "corn" shape provides uniform illumination and is perfect for: bedside lamps and bedside lamps, display cases, niches and accent lighting, lighting in campers/boats or rooms with 12V systems...
