Visual Product Overview & Application Context

Technical FAQ Deep-Dive

What are the primary applications for a 30W, 3,900-lumen LED vapor tight fixture?

This fixture is commonly specified for wet-location areas such as parking garages, industrial corridors, food processing zones, cold storage spaces, and any environment where exposure to moisture, dust, and frequent cleaning is routine. The 48-inch length is suitable for covering larger spans with uniform light distribution.

How does IP67 rating impact fixture installation in wet-location environments?

IP67 rating ensures that this fixture is protected from total dust ingress and can withstand submersion in water up to a certain depth and duration. This makes it ideal for environments where high-pressure washdowns and moisture exposure are common, such as car wash facilities and outdoor work zones.

How does IK10 impact the fixture's durability in industrial settings?

IK10 is an impact rating that indicates the fixture is resistant to mechanical damage. This is critical in environments with high traffic or potential for accidental impacts from carts, machinery, or personnel. The IK10 rating ensures the fixture can withstand harsh handling without failure, making it ideal for rugged industrial applications.

What is the luminous efficacy of this 30W, 3,900-lumen fixture?

3,900 lumens divided by 30W results in a luminous efficacy of 130 lm/W, which is a high efficiency for an LED vapor tight fixture. This high efficacy ensures that the fixture provides excellent light output with minimal energy consumption, helping to reduce operating costs over time.

How does the 110° beam angle affect light distribution and uniformity?

The 110° beam angle offers a wide distribution, ideal for large spaces where even light coverage is required. This wide angle helps reduce dark spots and ensures uniform illumination across work surfaces and floor areas, improving safety and productivity in industrial settings.

What does CRI 80+ indicate in terms of visual performance for industrial tasks?

CRI 80+ provides a good level of color rendering, ensuring that colors appear natural and clear, which is important in industrial and maintenance environments for tasks like equipment inspection, reading labels, and identifying safety markings. However, for applications requiring precise color matching, a higher CRI may be necessary.

What are the benefits of 0–10V dimming in wet-location applications?

0–10V dimming allows for energy-efficient control in environments with variable occupancy. Dimming capabilities can be integrated with occupancy sensors, so the light levels are automatically adjusted based on the presence of people, reducing energy consumption in unoccupied areas and ensuring that lighting levels are optimized for task performance when needed.

How does the -22°F minimum operating temperature affect fixture performance in colder environments?

The -22°F minimum operating temperature ensures that this fixture can perform in extreme cold conditions without failure. This is essential for outdoor applications, cold storage areas, or any unheated space where temperatures can drop below freezing. The fixture's ability to start and operate effectively in these conditions reduces maintenance costs and improves reliability.

How does the DLC Premium listing impact rebate eligibility and project costs?

The DLC Premium listing qualifies this fixture for utility rebate programs, offering potential cost savings on large-scale installations. This listing ensures that the fixture meets high-performance standards and energy efficiency requirements, making it an excellent choice for energy-conscious projects seeking to minimize upfront costs and improve ROI through rebates.

What does NSF rating ensure for the fixture's use in food processing or similar environments?

NSF rating ensures that this fixture meets sanitary standards for use in food processing and similar environments. This certification guarantees that the fixture is designed to withstand cleaning, prevent contamination, and comply with health and safety regulations in sensitive areas like kitchens, food storage, and manufacturing facilities.

How do the 50,000-hour rated life and 5-year warranty contribute to long-term reliability?

The 50,000-hour rated life provides long-term reliability and reduces the frequency of replacements, making this fixture ideal for areas with hard-to-reach installations. The 5-year limited warranty offers additional peace of mind, ensuring that any manufacturing defects or issues within the first five years will be addressed, further enhancing the fixture's overall value and performance.
