Celestial Star & Moon LED Diffuser vs Candlelight Flame Ultrasonic Diffuser

Buy the Celestial if you want a bigger tank, a star-and-moon light show and USB power for a bedroom or living room. Buy the Candlelight if you want a small, quiet, flame-look diffuser for a nightstand or desk. The Celestial holds more water and runs longer between refills; the Candlelight is smaller, rated under 30 dB and has auto shut-off. Owners of flame-style diffusers praise the realistic glow and quiet mist; the Celestial's light display is the draw, but its tank and mist output are less documented.

• Choose the Celestial Star & Moon if you want a larger tank, a decorative star and moon light, and USB-rechargeable power for a bedroom or living space.
• Choose the Candlelight Flame if you want a compact, near-silent diffuser with a realistic flickering candle glow and auto shut-off for a nightstand or desk.
