X5 SMD Series D145 LED OEM/ODM Downlight 15-20W

What is the X5 SMD Series D145 LED OEM/ODM Downlight and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineer lighting solutions for discerning specifiers in the EU, US, and Middle East. The X5 SMD Series D145 is a high-performance, general illumination LED downlight designed for commercial, retail, and hospitality applications. Operating at a versatile 15W or 20W, it fits a standard Ø125mm cutout, making it an ideal choice for both new construction and retrofit projects. With market-leading efficacy up to 130 lm/W, a vast range of CCT and CRI options, and a suite of professional control protocols, the D145 provides a reliable and aesthetically clean lighting foundation. This model is part of the wider X5 SMD family, which includes 10W (D110), 25W (D190), and 35W (D230) versions, allowing for a consistent design language across spaces with varying ceiling heights and illumination requirements.

Photometric and electrical specification

Which spaces is it designed for?

The X5 D145's wide 120° beam angle and high-quality light output make it an adaptable tool for lighting designers and contractors working on medium-to-large scale commercial projects.

How can this downlight be used to achieve uniform lighting in an open-plan office?

To meet modern workplace standards like EN 12464-1, uniform illumination is key. The X5's 120° beam allows for wider spacing between fixtures, reducing the total number of points required to achieve a target of 300-500 lux on task surfaces. For VDU-intensive areas, specifying the optional UGR<19 microprismatic lens is essential for visual comfort. We strongly recommend using our IES files in DIALux or other simulation software to verify spacing and achieve perfect uniformity before installation.

What are the best practices for specifying the X5 D145 in hotel corridors and lobbies?

In hospitality, atmosphere is paramount. For lobbies and corridors, a warm CCT of 2700K or 3000K creates a welcoming environment. Specifying a high CRI of Ra>90 ensures that interior finishes, artwork, and guest complexions are rendered beautifully. Integrating the DALI-2 driver option allows for sophisticated scenes, from a bright welcome during check-in to dimmed, energy-saving levels overnight. A typical spacing of 2.5 to 3 meters in a standard 2.8m high corridor provides excellent coverage.

Is the X5 series suitable for large-scale retail and showroom environments?

Absolutely. The X5 series excels in retail due to its combination of high efficacy and visual quality. The high lumen output (up to 2600 lumens in the 20W version) and efficiency (up to 130 lm/W) minimize energy consumption and running costs over a large floor area. For fashion or furniture showrooms, the CRI >95 or >98 options with excellent TM-30 metrics (Rf>90, Rg>100) ensure merchandise colours appear vibrant and true-to-life, directly impacting customer perception and sales. The consistent aesthetic across the entire 10W to 35W family allows a single design to be used from back-of-house to the main sales floor.

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

The luminaire is designed for quick installation with a standard Ø125mm hole saw and is secured with two durable spring clips. The external driver is connected via a simple plug, allowing for easy access and maintenance from below the ceiling. We offer a full spectrum of control solutions to meet any project requirement, from simple TRIAC phase-dimming to advanced, interoperable DALI-2 digital control for integration into building management systems. For retrofit projects or spaces where new control wiring is impractical, we offer wireless options including Casambi (Bluetooth Low Energy) and Zigbee. All configurations are fully compliant with EU standards, holding CE, RoHS, and the latest ErP certifications.

Customisation, MOQ and lead time

As an OEM/ODM partner, we offer extensive customisation. Beyond standard options, we can provide fixtures in any RAL colour to match corporate branding or interior design palettes. We can accommodate specific driver or LED chip requests to meet house standards for large rollouts. For large ODM projects, we can also modify housing or add branding. Our standard Minimum Order Quantity (MOQ) is 100 units for most configurations. The production lead time for standard orders is typically 20-25 working days from order confirmation to ex-works, with shipping times varying based on destination and freight method.

Frequently Asked Questions

Q: What is the standard warranty and expected lifetime?

A: The X5 SMD D145 comes with a comprehensive 5-year manufacturer's warranty covering both the luminaire and the external driver. The Epistar SMD LEDs are rated for L80B10 at 50,000 hours, ensuring long-term performance and minimal light depreciation in demanding commercial applications. This long lifespan significantly reduces maintenance cycles and total cost of ownership.

Q: Can I get a sample before placing a large order?

A: Yes, we encourage specifiers to request samples for evaluation and on-site mock-ups. We can provide 1-2 units of the X5 D145 downlight. While the samples are complimentary for qualified industry professionals, we typically ask the client to cover the international courier costs, which can range from $50-$100 depending on your location in the US or EU.

Q: What is the SDCM value for the LEDs used?

A: All CCT options for the X5 series are binned to a 3-step MacAdam ellipse (SDCM<3). This guarantees exceptional colour consistency from fixture to fixture, which is critical for creating a visually seamless and high-quality lighting installation across large open spaces like offices or retail floors. You can be confident that all 50 or 500 downlights in your project will look identical.

Q: How does the UGR<19 version differ from the standard model?

A: The standard X5 D145 uses a frosted polycarbonate diffuser for wide, general diffusion, resulting in a UGR of around 22. The optional UGR<19 version incorporates a specialized microprismatic lens. This advanced optic precisely controls light distribution, cutting off high-angle light that causes glare to meet the stringent requirements of EN 12464-1 for office task lighting.
