Firelight is calming in a way no overhead light can replicate. The movement, the warmth, the way it changes the feeling of a room at night. But real candles mean soot, hot wax, and the lingering worry of forgetting to blow them out before you fall asleep. Real fireplaces mean permits, wood, and maintenance. The EMBER creates the visual of a flickering flame through a smart LED combined with rising ultrasonic mist — and diffuses your essential oils at the same time. No flame. No risk. No wax. Just the ambiance.
Flame ambiance and aromatherapy. One device. No fire required.
- SIMULATED FLAME LED — CONVINCING AT DISTANCE: the smart LED light combines with the rising ultrasonic mist to produce a flickering-flame effect that reads as real fire from across a room. Up close it's clearly a diffuser — but the visual impression is strong enough to change the feeling of a bedroom, living room, or reading nook the way a lit candle would.
- 120ML ULTRASONIC MIST — HOURS OF AROMATHERAPY: the 120ml water tank diffuses essential oils into fine mist for a full evening session. Three mist modes — strong, weak, and breathing — let you adjust output to the room size and your preference. Add a few drops of lavender, cedarwood, or eucalyptus directly to the water before running.
- 7 AMBIENT MOOD LIGHTS: the bottom ring cycles through 7 colors — warm enough for bedrooms, soft enough not to disrupt sleep, versatile enough for living rooms or office desks. Use the flame simulation above, the ambient ring below, or both together for a full atmospheric effect.
- 3 TIMER MODES — 1H / 3H / 5H: set the EMBER to run for 1, 3, or 5 hours and it shuts off automatically. Run through a yoga session, an evening's wind-down, or a full movie. When the water tank runs dry, the water-shortage auto-off activates safely — no checking, no intervention, no overheating.
Aromatherapy combined with warm ambient light creates a stronger relaxation response than either stimulus alone.
coverage area — enough to scent a standard bedroom, living room, or reading nook on a single 120ml fill
mist modes (strong / weak / breathing) and timer options (1H / 3H / 5H) — the combination of controls you actually need
USB power draw — runs off a laptop port, any USB adapter, or a power bank without a dedicated outlet

How scent and light create atmosphere
Lavender, cedarwood, and chamomile essential oils activate GABA receptor pathways and have documented cortisol-modulating effects. Diffused consistently before sleep or wind-down, the scent becomes a conditioned relaxation cue — the limbic system's response to familiar calming scents is measurable in both EEG and hormone studies.
When the same sensory cues — scent and moving warm light — consistently precede rest, the brain forms an associative response. Over days and weeks of use, switching on the EMBER triggers the relaxation response before any other intervention, the same way the smell of a specific room triggers a memory.
Visible flame movement and diffused scent together create a stronger anchor for a wind-down ritual than either alone — the same principle behind candle use in meditation, prayer, and therapeutic settings across cultures. The visual element adds to the sensory completeness of the ritual.
For anyone who wants the atmosphere of firelight without an actual fire.
The candle lover
You love the feeling of candles in a room but you're tired of the soot, the wax drips, and the anxiety about forgetting to blow them out before you fall asleep.
EMBER gives you the flickering flame visual, the warm ambient glow, and the scent — diffused by ultrasonic mist. No smoke, no wax, no forgetting. Timer handles the shutoff.
The no-candle household
You live with children, pets, or a building rule that makes open flames a non-starter — but you miss the evening ambiance candles create.
EMBER produces the firelight effect with zero burn risk. USB-powered, timer-controlled, and safe to leave running unattended until the auto-off kicks in.
The aromatherapy user
You use essential oils for relaxation but your current diffuser is a plain plastic dome that doesn't add anything to the room aesthetically.
EMBER diffuses any essential oil you prefer through ultrasonic cold mist — while the flame LED and 7 mood lights make it an atmospheric object that earns its place on the shelf.
The meditation or yoga practitioner
You want to create a consistent sensory environment for your practice — scent, warmth, and a visual focal point — without expensive equipment.
Under-70dB at high mist, quieter at low. The flame effect and diffused scent create a consistent atmosphere that deepens through conditioned association over time.
The gift-giver
You want to give something genuinely useful and impressive — not a candle that burns out and not a gadget that collects dust.
The EMBER is the diffuser people don't know to ask for. The floating-flame effect is an immediate conversation piece. CB / CE / RoHS certified safe, beautiful enough to leave out permanently.
Fill. Add oil. Set the timer. Let the room change.
Fill the Tank
Remove the top of the EMBER and fill the 120ml water tank to the fill line. Add a few drops of your preferred essential oil directly to the water — lavender for calm, eucalyptus for clarity, cedarwood for grounding, or any blend. Replace the top.
120ml Water TankChoose Your Mode
Press the button to select mist strength (strong, weak, or breathing mode) and press again to set your timer — 1H, 3H, or 5H. The flame LED activates and the mood lights come on. Place on any flat surface near a USB power source.
1H / 3H / 5H TimerLet It Run
EMBER diffuses your oils and fills the room with scent while the LED creates the flame ambiance effect. When the timer runs out — or the tank runs dry — the auto-off activates safely. No wax, no smoke, no intervention.
Auto-ShutoffA real candle can't diffuse your oil, can't set a timer, and can't shut itself off.
