3. What is the height of a wall pack light?

The installation height of a wall pack light can vary significantly depending on various factors including the specific application, the design of the space, and the type of wall pack light being installed. Generally, wall pack lights are installed at heights ranging from 8 to 20 feet above the ground. Here are a few guidelines and considerations to help you determine the optimal installation height for wall pack lights:

 

General Guidelines

Commercial and Industrial Areas: In commercial and industrial settings, wall pack lights are typically installed at heights ranging from 15 to 30 feet to adequately illuminate large areas and ensure safety and security.

 

Residential Areas: In residential settings, wall pack lights might be installed at lower heights, typically between 8 and 15 feet, to illuminate walkways, driveways, and entrances.

 

Pedestrian Areas: In pedestrian areas such as walkways and paths, a lower installation height (e.g., 8 to 12 feet) might be more appropriate to create a welcoming and well-illuminated space.

 

Factors to Consider

Lumen Output and Beam Spread: Consider the lumen output and beam spread of the wall pack light. Higher lumen outputs and wider beam spreads may allow for higher mounting heights.

 

Purpose of Lighting: Consider the primary purpose of the lighting. For security lighting, a higher installation height might be preferable to cover a larger area, while for accent or architectural lighting, a lower height might be more appropriate.

 

Building Height and Architecture: The height and architecture of the building on which the wall pack light will be installed should be taken into account to ensure harmonious integration.

 

Expert Advice

Consult with a Lighting Designer or Engineer: If you're unsure about the optimal installation height for your wall pack lights, consult with a lighting designer or engineer to get expert advice based on your specific circumstances.

 

Lighting Simulations: In some cases, lighting professionals might conduct lighting simulations to determine the best installation height to achieve the desired lighting effect and coverage.

 

Safety Considerations

Avoid Glare: Installing wall packs at the correct height can help to avoid glare, which can be blinding and create safety hazards.

 

Uniformity of Lighting: Ensuring a uniform distribution of light by installing wall packs at the correct height can create a safer and more comfortable environment.

 

Adjustments and Fine-Tuning

Testing: After installation, it might be necessary to fine-tune the installation height based on the actual performance and coverage of the lights.

 

Adjustable Fixtures: Some wall pack lights come with adjustable fixtures that allow you to change the direction of the light beam, providing some flexibility in adjusting the lighting after installation.

Keep in mind that these are general guidelines and that the optimal height can vary depending on a wide range of factors. It's always best to consider the specifics of your individual project when determining the installation height for wall pack lights.

 

4. How long do LED wall packs last?

The lifespan of LED wall packs can vary based on a number of factors including the quality of the LED, the environment in which it is used, and how long it is used each day. However, many LED wall packs are rated to last for 50,000 to 100,000 hours of use.

 

To give you a more concrete idea, let's use the lower end of the range, 50,000 hours, to calculate the lifespan:

 

If used 24 hours a day, they can last about 5.7 years (50,000 hours ÷ (24 hours/day × 365 days/year))

If used 12 hours a day, they can last about 11.4 years (50,000 hours ÷ (12 hours/day × 365 days/year))

If used 8 hours a day, they can last about 17.1 years (50,000 hours ÷ (8 hours/day × 365 days/year))

However, towards the end of their lifespan, LEDs do not suddenly burn out but rather gradually dim over time. It is generally recommended to replace them when their brightness decreases to about 70% of their initial output, a point which is often referred to as the "L70 lifespan." Moreover, high-quality LEDs paired with good thermal management and drivers can potentially exceed their rated lifespans, offering even longer service lives.
