TP-R250 Round Tri-Proof Ceiling Bulkhead 18W

What is the TP-R250 and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we present the TP-R250 Round Tri-Proof Ceiling Bulkhead. This 18W luminaire is an engineering-grade solution designed for durability, efficiency, and safety in demanding commercial environments. Its 'tri-proof' designation signifies its resistance to dust, water, and impact, making it a reliable choice for areas where standard fixtures would fail. With its Ø250mm polycarbonate body and frosted diffuser, it provides a uniform, glare-reduced light output suitable for general illumination. Specifiers across Europe and the US select the TP-R250 for projects requiring a balance of performance and longevity, from office service corridors to hotel back-of-house spaces. We provide comprehensive support for lighting designers, including complete IES and LDT photometric files for seamless integration into DIALux and other lighting design software.

Which spaces is it designed for?

The TP-R250's robust construction and reliable performance make it a versatile workhorse for a wide range of functional and utility spaces in commercial buildings. Its design prioritizes safety, low maintenance, and energy efficiency.

How does it perform in high-traffic corridors and stairwells?

In stairwells and corridors, safety and reliability are paramount. The TP-R250 provides a wide 120° beam of light, ensuring floors and walls are evenly illuminated with minimal shadowing, typically achieving 100-150 lux required for safe transit. Its IK08 impact rating protects it from accidental bumps from carts or equipment, while the IP65 rating ensures that dust ingress and cleaning with water jets will not compromise its 50,000-hour lifespan. For added safety, it can be integrated with emergency battery packs.

Is it suitable for back-of-house areas in hotels and retail?

Absolutely. Back-of-house areas, such as storage rooms, loading docks, workshops, and kitchens, demand durable lighting that can withstand a challenging environment. The TP-R250’s polycarbonate housing is resistant to common cleaning agents, and its sealed IP65 construction prevents damage from moisture, steam, and airborne particles. With an operating temperature range of -20°C to +45°C, it functions reliably in both unheated storage and warm laundry rooms. The high power factor (PF>0.95) and efficacy of over 110 lm/W contribute to lower energy bills for the facility.

Can it be used in outdoor canopies or humid environments?

Yes, the TP-R250 is an excellent choice for covered outdoor areas like building entrances, walkways, and parking garage ceilings, as well as high-humidity indoor spaces like bathrooms, locker rooms, and plant rooms. The IP65 rating guarantees it is fully protected against rain spray and high humidity. The UV-stabilized polycarbonate body prevents yellowing or degradation from indirect sunlight, ensuring a long-lasting, clean appearance and consistent performance over its 5-year warranty period.

Installation, control and compliance (DALI-2 / Casambi / 0-10V, CE / RoHS / ErP)

The TP-R250 is designed for straightforward surface-mount installation on ceilings or walls. For a standard on/off configuration, it connects directly to AC 100-277V mains. For advanced lighting schemes, it can be specified with a range of dimming drivers. We offer 0-10V analog dimming for simple scene-setting, as well as DALI-2 drivers for addressable digital control and integration into building management systems (BMS). Wireless control via Casambi Bluetooth mesh is also available for retrofit projects where running new control wiring is not feasible. The fixture is fully compliant with European directives, holding CE (LVD/EMC), RoHS, and ErP certifications, ensuring it meets all safety, environmental, and energy efficiency requirements for the EU market.

Customisation, MOQ and lead time

As a manufacturer, we offer extensive customisation. While the standard model is 18W at 4000K, we can produce variants with CCTs from 2700K to 6500K, CRI >90 for color-critical applications, and alternative wattages. Housing can be finished in custom RAL colours to match project aesthetics. An emergency version with a 3-hour battery backup is also available. Our Minimum Order Quantity (MOQ) for standard configurations is typically 200 units. For custom specifications, the MOQ may vary. Standard production lead time is approximately 25-30 days from order confirmation, with shipping from our facility in China to major ports in the EU, US, and Middle East.

Frequently Asked Questions

Q: Can this fixture be supplied with a tunable white option?

A: Yes, the TP-R250 can be customized with a tunable white LED module. This allows for dynamic CCT adjustment, typically within a range of 2700K to 6500K. This option requires a DALI Type 8 (DT8) driver or a compatible two-channel 0-10V controller. This is ideal for applications aiming to support circadian rhythms in spaces like schools or healthcare facilities. Please specify this requirement when requesting a quote.

Q: Is an emergency lighting version available for this bulkhead?

A: Yes, we offer an emergency version of the TP-R250. It incorporates an integrated, self-contained battery pack and charging circuit. In the event of a power failure, it will automatically provide illumination for a duration of 3 hours at a reduced light output, compliant with EU standard EN 1838. The emergency module adds minimal bulk to the fixture and includes a status indicator LED.

Q: What does the IK08 rating mean in a practical sense?

A: The IK08 rating signifies a high level of impact resistance. According to the EN 62262 standard, the luminaire can withstand an impact of 5 joules of energy. This is equivalent to dropping a 1.7 kg mass from a height of 29.5 cm onto the fixture. Practically, this means it is protected against heavy bumps and acts of casual vandalism, making it ideal for public areas, schools, and transport hubs.

Q: What is covered under the 5-year warranty?

A: Our 5-year warranty covers defects in materials and workmanship for the entire luminaire, including the LED chips, driver, and housing. It guarantees that the fixture will maintain at least 70% of its initial luminous flux (L70) for its 50,000-hour rated lifespan under normal operating conditions. If a fixture fails due to a manufacturing defect within this period, we will provide a replacement part or complete unit.
