Frequently asked questions

  • Can I mix wattages across my parking lot?

    Yes. It is common to use different wattages in different zones — for example, 300W near building entrances or high-traffic lanes and 150W in lower-traffic perimeter areas. Just ensure each fixture's lumen output is matched to its mounting height and spacing for uniform coverage.

  • Do I need a separate photocell or is it included?

    The photocell sensor is included with every fixture in this series. No additional purchase is needed for basic dusk-to-dawn automation.

  • What certifications does this product have?

    The fixtures carry ETL listing (equivalent to UL, accepted by AHJs across North America), FCC certification, and RoHS compliance. ETL listing is required by most commercial building inspectors and insurance carriers. California Proposition 65 warning applies — see product packaging.

  • Are these lights available for bulk or commercial project orders?

    Yes. For large parking lot, campus, or municipality projects requiring multiple units, contact G GJIA LED Lighting directly for project pricing and lead time: 📞 +1(346)490-6412 📧 sales@ggjia-led.com 📍 10647 W. Airport Blvd, Suite 200, Stafford TX 77477 USA

  • What does a 150W LED parking lot light replace?

    21,000 lumens replaces a 400W metal halide or HPS fixture, maintaining brightness while saving over 80% on energy.

  • What pole height is best for a 150W parking lot light?

    15-20 ft poles for standard parking rows and smaller commercial lots. For taller poles or wider spacing, step up to 200W or 300W.

  • Is the 150W the entry-level parking lot light?

    It's the lowest-wattage shoebox in the GGJIA parking lot line, ideal for standard parking rows, driveways and small lots. Larger areas or taller poles need 200W, 300W or 400W.

  • Does it include a photocell and dimming?

    Yes — built-in dusk-to-dawn photocell plus 0-10V dimming.

  • Can I install it myself?

    Yes, Mechanical mounting with basic tools; electrical work by a licensed electrician per NEC and to keep warranty valid.
