PRODUCT STATUS: Standard product architecture with model-specific engineering confirmation

1. Product Introduction & Positioning

Columus COB400SP is an advanced external-driver LED inflatable light tower using a high-power 400 W COB platform. The external constant-current driver enables stable operation and a wide range of control options, including remote switching, dimming, DMX and APP/wireless integration when specified.

Series positioning: SP - Standard Pro (Professional / upper-standard). The tower uses premium translucent flame-retardant, uv-resistant composite envelope and is intended for industrial night work, emergency response, rescue, infrastructure, mining, ports, airports, professional event support and film/TV support zones. This model should be selected from required illuminance, work-zone size, tower height, power source, restart behavior, color/flicker needs and environmental conditions rather than lamp wattage alone.

4. Lighting Performance & Application Boundary

For project planning, COB400SP is estimated to provide a maximum low-level illumination footprint of approximately 5,400 m² at the 1-lux boundary and approximately 1,080 m² at 10 lux. For general orientation, emergency staging and broad work-zone lighting, a more practical 10-20 lux planning range is approximately 540-1,080 m². Applications requiring 50-100 lux or more will cover a much smaller area and should be checked with a project-specific lux layout.

Application boundary: Higher BOM cost than direct-AC SMD, but preferred where stability, dimming and advanced control are important.

Recommended Applications

· Professional construction and municipal work

· Emergency/rescue staging

· Rental fleets requiring instant start and dimming

· Event/film support where low-flicker control is specified

Representative Application Cases

Case 1. Rescue / emergency staging with remote dimming or optional battery / AC-DC operation.

Case 2. Municipal maintenance and construction where instant start and adjustable output are preferred.

Case 3. Professional event or film-support area requiring low-flicker driver selection and advanced control.

Cases above are representative application scenarios for positioning and selection. They are not claims of a named customer installation unless supported by a separately approved project reference.

5. Customer Value & Selection Guidance

· Instant start

· Advanced dimming / remote / DMX / APP potential

· Low-flicker driver options

· Stable external-driver architecture

Choose COB400SP when its led - cob behavior, 400 W output class and SP series positioning match the project priorities. If the customer needs different restart behavior, control sophistication, budget level or tower material, compare related Columus models rather than increasing wattage alone.

6. Customization & OEM/ODM Options

· Tower height: 2.0 / 2.5 / 3.0 / 4.0 / 5.0 m project options; 3.0 m and 4.0 m are the most common family configurations.

· Envelope color, logo printing and project identification graphics, subject to material and print-process suitability.

· Input voltage, plug type, cable length, connector arrangement and generator interface for the target market.

· Light-source package: 5000-5700 K standard planning range; 3000 K / 4000 K / 6500 K or project-specific CCT can be evaluated; color rendering options follow the selected lamp/LED package.

· Protective transport packaging: reinforced export carton, plywood case or reusable flight case depending on project and shipping mode.

· Guy ropes, pegs, sandbags/ballast points, spare envelope, spare electrical parts and extension cables can be supplied as project accessories.

· Remote on/off, dimming, DMX, wireless / APP control, low-flicker driver and project-specific control interfaces.

Customization is subject to engineering review, component availability, certification scope and final quotation. Drawings, control architecture, logo artwork and special packing may require approval before production.

10. FAQ

Which tower height should I choose?

The family supports 2.0-5.0 m project heights. For COB400SP, the normal recommendation is 3.0-4.0 m. Final height should be selected from required lux, coverage, wind exposure and transport limits.

How large an area can it illuminate?

The planning reference is up to about 5,400 m² at the very low 1-lux boundary and about 1,080 m² at 10 lux. A more practical 10-20 lux working-zone planning range is about 540-1,080 m². Higher task-light levels reduce the effective area substantially.

Can it run from batteries?

Yes, this model can be engineered for battery DC or switchable AC/DC use.

Is the light flicker-free?

Low-flicker / flicker-controlled drivers can be specified. Camera or high-speed filming performance must be defined in the project requirement.

Can CCT and CRI be customized?

5000-5700 K standard planning range; 3000 K / 4000 K / 6500 K or project-specific CCT can be evaluated. Ra >=80 standard planning basis; Ra >=90 option available subject to LED bin, efficacy and thermal design Final availability depends on the selected lamp/LED package.

Is it waterproof and wind resistant?

The system is designed for outdoor temporary use, but the exact IP declaration and permitted wind speed must be confirmed for the approved electrical package, tower height, base and guy-line/anchoring method. Do not treat a legacy value as universal across all 2026 models.

Can our logo be printed on the tower?

Yes. Logo, project identity and selected graphics can be applied to compatible envelope materials. Artwork and print area are confirmed before production.

What are the warranty and lead time?

Reference warranty is 12 months against manufacturing defects from shipment, subject to final quotation/sales contract and exclusions for consumables, lamps, batteries and misuse. Typically 15-25 working days for standard confirmed configurations; customized versions typically 20-35 working days.
