Frequently asked questions

  • Does my loading dock legally require a dock light?

    OSHA standard 29 CFR 1910.36(b)(3) mandates adequate lighting at all loading docks — a minimum of 5 foot-candles for equipment operation areas, and higher levels for task-intensive work like label reading and goods inspection. The IES RP-7-20 standard recommends 50–100 lux (5–10 foot-candles) horizontal and up to 200 lux (20 fc) vertical for critical inspection tasks. OSHA reports that 25% of all warehouse injuries occur on loading docks, making proper lighting a key safety investment.

  • Is the UL listing required for my insurance or building permit?

    Many commercial property insurance policies, local building codes, and AHJ (Authority Having Jurisdiction) requirements mandate UL-listed or ETL-listed electrical fixtures in commercial and industrial settings. The GJIA A1 and B2 dock lights carry UL certification, making them suitable for permitted commercial installations across the US and Canada. Always confirm your local jurisdiction's requirements with your electrical contractor or facility manager.

  • Is the GJIA dock light suitable for use in Canada?

    Yes. The UL listing covers North American safety standards recognized in both the United States and Canada. The wide voltage range (100–277V) is fully compatible with Canadian electrical systems. FCC and RoHS compliance are also recognized in Canada.

  • How much energy will I save compared to my old dock light?

    A traditional 150W incandescent or 100W metal halide dock light replaced by a 30W GJIA LED saves 80–85% on energy per bay. At 12 operating hours per day, 365 days per year, at an average US commercial electricity rate of ≈0.13/kWh, a single 30W GJIA light costs roughly $17/year to run vs. ≈$85/year for a 150W incandescent — saving ≈$68 per bay annually, with payback typically achieved in under 2 years.

  • How long will the light last, and what is the maintenance cost?

    The rated lifespan is 50,000 hours — equivalent to over 11 years of 12-hour-per-day operation. Unlike incandescent or HID dock lights that require frequent bulb replacements (often every 1,000–6,000 hours), the GJIA LED unit has no replaceable bulb. This virtually eliminates lamp replacement labor and parts costs over the life of the fixture.

  • Is there a rebate available for LED dock lights in the US or Canada?

    Many US utility companies and Canadian provincial programs offer rebates for commercial LED lighting upgrades, particularly for facilities in the industrial sector. Contact your local utility provider or visit your state/provincial energy office website to find available incentive programs. Products with DLC (DesignLights Consortium) certification are most commonly eligible — check the current GJIA product listing for DLC status.

  • Beyond loading docks, what other applications are the lights suited for?

    The GJIA A1 and B2 dock lights are designed for any environment requiring a bright, directional, durable work light. Common applications include: distribution center dock bays, shipping container inspection, warehouse workbenches, manufacturing plant assembly stations, packaging lines, automotive garage bays, courtyard and outdoor security lighting, and general-purpose industrial spotlighting.

  • Can I use it inside a refrigerated or cold-storage trailer?

    Yes. The IP65 rating and LED technology (which operates in cold environments without warm-up delay) make the GJIA dock light suitable for illuminating refrigerated trailers and cold-storage containers. The 30° beam angle effectively lights the interior of a cold-storage unit from the dock door without spilling wasted light sideways.
