Frequently asked questions

  • What is the IP rating and what does it mean?

    These fixtures are rated IP66, which means: 6 = Fully dust-tight (no ingress of dust) 6 = Protected against powerful water jets from any direction IP66 exceeds the IP65 minimum commonly required for outdoor commercial fixtures, making these suitable for harsh weather including heavy rain, sleet, and coastal environments.

  • What is the operating temperature range?

    -31°F to 122°F (-35°C to 50°C). This covers virtually all North American climate zones, from Canadian prairie winters to desert summers in the American Southwest.

  • Is there surge protection built in?

    Please refer to the individual product listing for surge protection ratings. As a best practice for any outdoor fixture exposed to lightning risk, an external 10kA or 20kA surge protective device (SPD) installed at the pole base or panel is recommended for critical installations.

  • Will the aluminum housing corrode over time?

    The fixture uses a die-cast aluminum alloy housing, which is inherently corrosion-resistant. For coastal or high-salt environments, standard anodized or powder-coated aluminum performs well long-term. No special maintenance is required beyond periodic cleaning of the lens surface.

  • How long will these lights last?

    The estimated L70 lifetime is >70,000 hours at 25°C (77°F). L70 means the fixture retains at least 70% of its original lumen output at that point — the industry standard threshold for "end of useful life." Running 12 hours per night, that equates to approximately 16+ years of service life.

  • What is covered under the 5-year warranty?

    The limited 5-year warranty covers manufacturing defects and premature failure under normal operating conditions. For specific terms (what's included, what's excluded, and the claim process), contact G GJIA LED Lighting at sales@ggjia-led.com or +1(346)490-6412.

  • What happens if a fixture fails within the warranty period?

    Contact G GJIA's support team with your proof of purchase and a description of the issue. Warranty claims typically result in a replacement unit being sent. Defective products should not be discarded until the claim is resolved.

  • How much can I save on electricity by switching from metal halide to LED?

    Switching from a 1,000W metal halide to a 300W LED saves 700W per fixture per operating hour. At a U.S. average commercial rate of ~$0.12/kWh, running 12 hours/night, that's roughly $365 per fixture per year in electricity savings alone. For a 20-fixture parking lot, that's over $7,000 annually.

  • Do these lights qualify for utility rebates in the US or Canada?

    Many utility companies offer rebates for LED upgrades that replace HID fixtures, often covering 20–40% of fixture costs. Rebate eligibility generally requires: DLC (DesignLights Consortium) listing — please verify for specific SKUs Replacement of qualifying legacy technology (metal halide, HPS, etc.) Minimum wattage reduction and/or LPW threshold Check your utility's rebate portal or visit dsireusa.org (for US) to find programs in your area. Contact us for documentation that may support your application.

  • What is the typical payback period for switching to LED parking lot lights?

    Most commercial LED retrofit projects achieve payback in 2–4 years when combining energy savings with utility rebates and reduced maintenance costs (no bulb/ballast replacements). Larger projects with more fixtures and higher electricity rates typically see faster payback.
