— Frequently Asked Questions

LED Flood Lights — Buyer Questions Answered

Direct answers to the questions specifying engineers, EPC contractors, and procurement teams ask before placing an order.

What power range do Sunjoylight LED flood lights cover?

Sunjoylight LED flood lights cover 50W to 1200W across 11 model series (SJTG601, SJTG602, SJTG603, SJTG604, SJTG605, SJTG606, SJTG608, SJTG609, SJTG610, SJTG611, SJTG612). The SJTG610 flagship can scale up to 1200W for ultra-large area projects like stadiums and ports. Lumen output ranges from 6,500 LM (50W) to 192,000 LM (1200W).

What IP rating do these LED flood lights have?

All Sunjoylight LED flood lights are rated IP65, meaning they are dust-tight and protected against low-pressure water jets from any direction. They are tested in our in-house IP rating chamber. The die-cast aluminum housing with silicone gasket and tempered glass front cover ensures reliable operation in outdoor industrial environments including warehouses, ports, sports fields, oil & gas yards, and roadway projects.

What is the minimum order quantity (MOQ) and lead time?

Minimum order quantity is flexible — typically 100-500 pieces depending on the model series and customization required. Standard lead time is 15-25 days for in-stock configurations. OEM/ODM orders with custom wattage, voltage, beam angle, or branding typically ship within 30-45 days after artwork approval and sample confirmation.

Do you provide IES files and photometric data for lighting design?

Yes. IES and LDT photometric files are available for every model series, fully compatible with DIALux, Relux, and AGi32 lighting design software. LM-79 (photometric) and LM-80 (lumen maintenance) test reports are provided on request. Spec sheets include full photometric curves, beam angle distributions, and luminous intensity diagrams.

What is the warranty on Sunjoylight flood lights?

Standard warranty is 5 years across all 11 flood light series. The rated lifespan is over 50,000 hours based on LM-80 test data. Junction temperature is kept below 65°C in full-load testing, ensuring long-term reliability. Replacement parts are stocked for the warranty period.

Can you customize the wattage, beam angle, or branding (OEM/ODM)?

Yes — Sunjoylight is a true OEM/ODM manufacturer with full in-house capability. We can customize wattage (50W to 1200W), beam angles (15°, 30°, 60°, 90°, asymmetric distributions), color temperatures (2700K-6500K), voltages (100-277V, 347V, 480V options), housing finish, branding, and packaging. Minimum order applies — typically 500+ units for custom OEM.

What applications are these flood lights best suited for?

Sunjoylight LED flood lights are deployed across four primary application sectors: (1) Industrial & Manufacturing — factory floors, warehouses, distribution centers, assembly lines, loading docks; (2) Commercial & Public Spaces — building facades, billboards, parking lots, plazas; (3) Special & Harsh Environments — ports, terminals, oil & gas yards, mining sites; (4) Agriculture & Other Fields — greenhouses, livestock facilities, rural roads.

What is the brightest LED flood light you make?

The SJTG610 flagship scales to 1200W, the highest single-fixture output in our range. But "brightest" is better answered with a measurement than a wattage: our 200W-class unit measured 35,309 lm at 201.3 W on a distributed goniophotometer, with a peak intensity of 34,444 cd — which at 8 m mounting delivers roughly 538 lux directly beneath the fixture. Peak candela and beam angle, not the lumen headline, decide how bright a flood light actually is at your mounting height. The full report is downloadable on this page.

What is a high lumen LED flood light, and what output should I expect per watt?

A high-lumen flood light is one whose measured whole-fixture output — not summed LED chip figures — is high relative to its input power. Our range runs 120–160 lm/W across the series, and the tested 200W unit measured 175.4 lm/W on the complete fixture. The distinction matters commercially: chip-lumen arithmetic typically overstates real fixture output by 10–20%, so always compare measured LM-79-style whole-fixture data rather than catalogue claims.

Are LED flood lights energy efficient compared with metal halide?

Substantially. LED flood lights typically draw 50–70% less power for equivalent delivered light, because directional optics put lumens on the target instead of into the sky, and there is no restrike delay or ballast loss. Our tested 200W unit returned an EEI of 0.081 (energy class A++) with a measured power factor of 0.986 — power factor matters because a poor one inflates apparent load and heats wiring across a multi-fixture installation. Adding motion or photocell control on top typically cuts consumption again on low-traffic positions.

Are your LED flood lights dimmable?

Yes — dimmable drivers are configured at order stage, with 0-10V and DALI protocols available depending on the series, plus photocell and motion-sensor options. Specify the control protocol with the order: retrofitting a dimmable driver into a sealed IP65 flood body afterwards means opening the fixture and its gasket, which is both a labour cost and an ingress risk.

Do you make solar flood lights as well?

Yes. Our solar flood range spans 50W to 500W across two families — SJTG620S with a remote panel, so the head can aim at a sign or facade while the panel faces the sun, and SJTG621S, a slim aluminium projector for larger areas. They suit positions where trenching a cable costs more than the light: yard corners, gates, billboards, flagpoles, perimeters and farm buildings. Panel and battery are sized to your location's worst-month sun-hours rather than a universal runtime figure.

Which Sunjoylight flood light series should I choose for a stadium project?

For stadium and large-area sports lighting, the SJTG611 (100W-400W modular) or SJTG610 (50W-1200W flagship) are most commonly specified. The SJTG611 features independently rotatable modules with set screws for orientation lock, plus high-transparency PC optical lenses. The SJTG610 uses a Matrix Glass Lens with 95% light transmittance and a Climax Grille Structure for superior heat dissipation, supporting up to 1200W output per fixture.

— About the Manufacturer

Who Makes Sunjoylight LED Flood Lights

Sunjoylight is the export brand of Changzhou Shuangjia Electrical Appliance Co., Ltd. (also marketed under the LUYI® brand domestically), an industrial LED lighting manufacturer founded in 1999 and headquartered in Changzhou, Jiangsu Province, China. With over 25 years of continuous operation, the company specializes in engineered LED solutions for warehouses, oil & gas facilities, mining operations, ports, sports venues, and roadway infrastructure projects worldwide.

The Floodlight Series comprises 12 distinct model families — from the compact SJTG601 50W reflector design up to the flagship SJTG610 Matrix Glass Lens fixture that scales to 1200W for ultra-large-area illumination. Every fixture is built around a die-cast aluminum housing, Lumileds 3030 LED chips, high-temperature tempered glass front cover, and IP65-rated silicone gasket sealing.
