Types of LED Wall Pack Lights

Understanding the different types of LED wall pack light fixtures available is essential for selecting the appropriate solution for specific applications. The distinction between full cutoff and non-cutoff designs represents one of the most important considerations. Full cutoff fixtures are designed to prevent light from escaping above the horizontal plane, directing illumination downward where it's needed while minimizing light pollution and skyglow. This design is particularly important in urban environments like Hong Kong, where excessive upward light can contribute to the city's notable light pollution issues.

Non-cutoff fixtures, while sometimes providing wider distribution patterns, allow light to escape above the horizontal plane. These may be suitable for certain applications where broader illumination is required, but they typically contribute more to light pollution. Many municipalities, including several districts in Hong Kong, have implemented lighting ordinances that require or encourage full cutoff designs for outdoor lighting, making this an increasingly important specification consideration.

Wattage and lumen options vary significantly across different LED wall pack models, allowing for precise matching to application requirements. Common wattages range from 20W for residential pathway lighting to 100W or higher for large commercial or industrial applications. The relationship between wattage and light output has been transformed by LED technology, with modern fixtures delivering substantially more lumens per watt than traditional technologies.
