Refresh the Look of Your Home with a Gorgeous Fireplace that has Multicolor Flames

Do you feel sometimes that your indoor space is suffocating? What you need is a fireplace to set a cozy ambiance in your living space. There is a common notion that fireplaces are unsafe and difficult to put up. But, the Modern Flames Spectrum Slimline Electric Fireplace solves that problem.

The improved version of the Spectrum features Hybrid-FX™ Flame Technology, 12 flame colors, and 12 ember bed colors. Available in four sizes: 50" to 100" wide, this visually stunning fireplace is perfect for adding style, warmth, and ambiance to any room.

Spectrum Slimline electric fireplace is less than 5" deep and designed for wall mount or recessed installation. Wall mounting this fireplace is quite easy using the mounting brackets that come with it. Two people can do the job. Clean face or 2" x 4" installation may require a bit more work as hardwiring this fireplace requires a qualified electrician.

Modern Flames' Hybrid-FX™ Flame Technology is an enhanced version of their realistic award-winning flame technology. This new technology allows independent control of the flame and ember bed colors resulting in more color combinations and more vibrant flames. A large viewing area with a sleek 5/8" trim and colorful display, further enhanced with logs and glass media, both come with the fireplace, making this fireplace an eye-catching wall accent.

Spectrum Slimline is more than just a decorative piece as it can easily heat up a small room or provide supplementary heat to a large room. At its highest setting, it is capable of producing 5,000 BTUs of heat, which is good enough to heat a room up to 450 square feet. Or, set it to a particular temperature from 68 to 88 °F using the touch control panel or included remote.

Look forward to coming home to a cozy ambiance and pleasing atmosphere in your room. Buy the Modern Flames Spectrum Slimline Electric Fireplace today and enjoy free shipping from us!
