FireGarden Tempest Lantern 20K Outdoor Gas Lantern
Overview
The FireGarden Tempest Lantern transforms an open flame into living sculpture. Its patented four-sided tempered glass housing channels combustion air to accelerate the flame into a mesmerizing spiral, producing a true venturi effect of fire in motion without any fan or moving parts. The result is a dramatic, weather-resistant gas lantern that elevates entryways, patios, pool decks, and landscapes with the warm glow of real flame.
Engineered for the elements, the open-air housing keeps the flame burning through high wind and rain, while an automatic gas safety shutoff valve closes the supply should the flame ever go out. Choose manual rotary piezo ignition for effortless lighting, or the all-weather 24V Hot Shot electronic ignition for control via light switch, remote, timer, or smart-home integration.

What Our Customers Say
Frequently asked questions
Will fireplace doors save energy?
Yes. When closed during periods the fireplace is not in use, glass doors seal the firebox opening — preventing warm indoor air from escaping up the chimney and blocking cold drafts from entering. This is one of the most common reasons buyers add doors to a masonry fireplace, where an open damper can lose hundreds of cubic feet of conditioned air per minute.
Can I close the doors while a fire is burning?
It depends on the door type. Most masonry-fireplace doors with tempered or ceramic glass are designed to be operated open while a wood fire burns at full intensity, then closed once the fire has burned down to embers. Always check the manufacturer's instructions for your specific model. Doors with mesh curtains can stay closed during active fires — the mesh blocks sparks while letting heat radiate through.
How do I measure for fireplace doors?
Measure the firebox opening at three points each direction (top, middle, bottom for width; left, center, right for height) and use the smallest measurement. For overlap-fit doors, add room for the frame overlap (typically +2" width / +1" height). For inside-fit, subtract clearance (-1" width / -½" height). Every custom order ships through our free Expert Fit Review — we verify your measurements before production.
What's the warranty on EF fireplace doors?
All doors carry a 5-year warranty against frame defects. The powder-coat finish is warranted against chipping and fading for 5 years. Glass and mesh are warranted against defects for 1 year. Damage in transit is fully covered — file a claim within 48 hours of delivery.
Do you offer free shipping and returns?
Free freight shipping on all orders within the contiguous US. Custom-made doors are non-returnable because every order is verified through Expert Fit Review before production — no measurement risk on your end. Quick-Ship inventory items have a 30-day return window on unused, uninstalled units.
