It runs on normal household voltage (110-125V) and is energy-friendly, helping to lower electricity bills while still delivering strong airflow.

The fan includes a wired wall controller and offers app-based control options for easy adjustment of settings. Weighing 70 pounds, it is primarily intended for indoor use and may require professional installation due to its weight.

The Haiku L by Big A Fans is a 52-inch ceiling fan designed for energy-efficient cooling. Its motor is specially engineered to deliver excellent performance while minimizing power consumption, making it a strong choice for those focused on energy efficiency. The fan's operation is whisper-quiet, thanks to meticulous hand-balancing of its airfoils, which prevents wobbling and squeaking – a great feature if you value a peaceful environment.

It provides optimal air circulation in spaces up to 15' x 15', making it suitable for rooms like bedrooms, living rooms, or offices.

The Haiku L comes with a 5” downrod for ceilings between 8 to 9 feet, although additional downrod lengths are available for purchase if needed. However, some users may find the setup slightly complex due to the range of included components and additional purchases required for different ceiling heights. Despite its strengths, potential buyers should consider the installation requirements and ensure compatibility with their ceiling height and space.
