Indoor LED specification usually starts with a brightness target and ends with a format argument: should the space be lit by a high-density linear fixture, a magnetic track system, or an LED strip? XPUP LED, the export brand of Zhongshan Xiangpai (XPUP) Lighting Technology Co., Ltd. — an LED strip and linear lighting manufacturer established in 2012 in Zhongshan, China — builds all three. This guide compares five published products from that range so specifiers, procurement managers and interior design teams can match format to task before the discussion moves to price: the DK3-DC24V-2835-240D-9.3mm linear fixture, the XP-BD18DC24V-2835-140D-8MM full-spectrum strip, the XP-CX-18 magnetic track light, the XP-SM-DC24V-5050-10MM smart strip, and the XP-ZS-DC24V-2835-8MM decorative strip.

Full-spectrum strip lighting (XP-BD18DC24V-2835-140D-8MM, Ra≥97) — one of the three indoor LED formats compared in this guide.

Problem Definition: The Format Decision Comes Before the Fixture Decision

Three failures repeat across indoor commercial and hospitality projects, and all three are format problems rather than brand problems.

1. Visible LED dots. When a strip with a low LED count per metre sits behind a shallow diffuser or inside a slim profile, the source reads as separated points instead of a continuous line. The DK3 linear model addresses this directly: 240 LEDs per metre on a 9.3 mm PCB, described in its published specification as high density with uniform light emission and no grainy appearance, intended for indoor lighting strips and black profiles.

2. Colour complaints after handover. In jewellery stores, museums, galleries and luxury retail, the limiting factor is rarely wattage — it is colour rendering. Two strips can deliver comparable brightness while rendering gemstones, fabrics or finishes very differently. A Ra≥80 decorative strip and the XP-BD18 full-spectrum strip rated Ra≥97 are not interchangeable inside a display case.

3. System mismatch. Format choice also fixes the electrical architecture. Magnetic track lighting in this comparison runs on a 48V system (XP-CX-18), while the strip and linear products run on 24V DC. A project that mixes formats needs supply and control layers planned together; discovering the mismatch after the ceiling is closed is the expensive version of the decision.

Every option below is therefore judged against the same decision criteria — CRI, voltage, power, LED density, PCB width, control and intended application — rather than against a single notion of the best format.

Industry Background: Where Indoor LED Demand Sits

Indoor work carries the volume. Grand View Research valued the global LED lighting market at USD 106.9 billion in 2025 and projects USD 197 billion by 2033, while its 2024 estimate for commercial lighting was USD 47.54 billion. Within smart lighting, Precedence Research reported that indoor lighting generated 66% of market share in 2024, which is consistent with the fact that the formats compared here serve interior applications rather than outdoor or industrial installations.

At format level, three different growth engines sit behind one specification conversation:

• Linear lighting: Maximize Market Research valued the linear lighting market at USD 30.09 billion in 2025, with an 11.42% CAGR projected to 2032.
• Magnetic track lighting: Dataintelo valued the magnetic track lighting system market at USD 2.8 billion in 2025, with a 7.6% CAGR expected through 2033. This is a medium-reliability estimate and should be read as directional.
• Smart and human-centric lighting: Grand View Research valued the global smart LED lighting market at USD 27.3 billion in 2024, and Research Nester estimated the human centric lighting market at USD 3.66 billion in 2024 with a 17.1% CAGR through 2036 (medium reliability).

Hospitality is a separate demand pool. Dataintelo placed the hospitality lighting market at USD 14.2 billion in 2025 (medium reliability), which matches the project pattern behind XPUP LED’s export work, where hotel public areas, restaurants, aparthotels and resort interiors generate repeat orders for both LED strips and linear formats.

Regulation adds a hard constraint to format selection. The 2024 International Energy Conservation Code (IECC), published by the International Code Council, requires lights in commercial interiors to dim to 10% or lower. That requirement sits with the control layer rather than the light source: a strip or track product that cannot reach the required dimming level with its controller does not comply, regardless of its CRI or wattage.

Detailed Solution: The Five XPUP LED Products in This Comparison

XPUP LED manufactures LED strips, linear lighting and magnetic track lighting as a source manufacturer, with CE and RoHS certification across its export range. The five models below are the specific products this comparison is built on. All specifications are quoted as published; project-specific configurations are confirmed at sample stage.

DK3-DC24V-2835-240D-9.3mm — High-Density Linear Lighting

DK3 linear lighting: 240 LEDs per metre on a 9.3 mm PCB for uniform, dot-free light emission.

Choose it when the brief calls for unbroken linear runs with no visible LED structure — office and restaurant lines, coves and recessed profiles, including black-profile installations.

XP-BD18DC24V-2835-140D-8MM — Full-Spectrum Strip

XP-BD18 full-spectrum strip: Ra≥97 colour rendering for museums, galleries and jewellery display cases.

Choose it when the light itself is part of the product presentation. The published selling points note ultra 5 mm/8 mm linear strip options at Ra90/Ra97 with each LED cuttable for various lengths, high brightness, good flexibility and strong bending resistance — a combination intended for jewellery stores and display cases.

XP-CX-18 — 48V Magnetic Track Light

XP-CX-18 magnetic track light: 48V, 30W, 120° beam angle, aluminium and PC construction.

Choose it when aiming flexibility matters more than a continuous line. The published description positions this format for commercial and exhibition settings where lighting should make commodities or exhibits more intuitive, enhance material texture and create a more artistic atmosphere; typical venues include clothing stores, jewellery stores, exhibition halls, hotels and clubs. Imported PC cover material is used for the 120° beam.

XP-SM-DC24V-5050-10MM — Smart Strip

XP-SM smart strip: RGB plus 3000K / 4000K / 6000K white on a 10 mm double-layer copper PCB.

Choose it when one installation must serve both task lighting and atmosphere — white light for service hours, colour programming for evening operation, on the same 24V circuit.

XP-ZS-DC24V-2835-8MM — Decorative Strip

XP-ZS decorative strip: 24V background and feature lighting for hotels, restaurants, retail and architecture.

Choose it when the lighting task is background decoration rather than merchandise rendering — wall grazing, cove lines and feature ceilings across hospitality and retail interiors.

Shared installation conditions for this group: indoor dry environments, operating temperature −20°C to +45°C, no covering with objects, no chemically corrosive environments, and the use of a proper power supply or adapter to avoid overload.

A second view helps when the requirement is already fixed. The matrix below maps a project requirement to the format that satisfies it first:

Project requirement	First choice	Reason from published data
Accurate colour on merchandise and exhibits	XP-BD18DC24V-2835-140D-8MM	Ra≥97, 140 LEDs per metre, 55–65 LM/LED, cuttable per LED
Continuous line with no visible LED dots	DK3-DC24V-2835-240D-9.3mm	240 LEDs per metre with high density and uniform emission
Aiming and repositioning of accent light	XP-CX-18	48V magnetic track format, 30W, 120° beam angle
White task light plus colour atmosphere	XP-SM-DC24V-5050-10MM	RGB / 3000K / 4000K / 6000K, adjustable brightness and speed modes
Long decorative runs without voltage drop	XP-ZS-DC24V-2835-8MM	20 m non voltage drop, 60D or 140D per metre

Step-by-Step Breakdown: How to Specify the Right Format

1. Define the lighting task, not the product. Separate merchandise rendering, general illumination and background decoration. A display case and a cove line rarely belong to the same product family.
2. Set the CRI floor from what the light touches. Ra≥97 for jewellery, museum and gallery objects; Ra≥90 for retail interiors, restaurants and hospitality front-of-house; Ra≥80 is normally sufficient where light falls only on architecture.
3. Fix the electrical architecture early. Decide between 24V strip and linear systems (DK3, XP-BD18, XP-SM, XP-ZS) and 48V magnetic track (XP-CX-18). Mixed-format ceilings need both supply and control planned together.
4. Match LED density to the profile depth. 240 LEDs per metre (DK3) fits slim and black profiles with no grainy appearance; 60D configurations leave more spacing and therefore need deeper diffusion.
5. Decide the control requirement. If the project falls under commercial interior codes such as the 2024 IECC 10% dimming threshold, confirm the controller and driver can reach that level before the format is approved. For colour programming, confirm RGB and white channel behaviour on the XP-SM or XP-ZS configuration.
6. Confirm the installation environment. All five formats are indoor products; published conditions are an indoor dry environment, −20°C to +45°C, no covering, no corrosive atmosphere and a correctly rated power supply.
7. Validate on a sample. Check colour rendering against the actual merchandise, temperature consistency across the run, bending radius inside the specified profile, and control compatibility with the project controller.
8. Lock the commercial terms. XPUP LED publishes a minimum order quantity of 2,000 metres, a lead time of 18–22 days, a monthly capacity of 3,000,000 metres, 100% testing and a 2-year standard warranty, with 18–22 day delivery quoted for OEM and ODM programmes.

Use Cases: Matching Format to Project Type

Museums, galleries and jewellery retail

Colour accuracy governs the decision. The XP-BD18 full-spectrum strip at Ra≥97 with 140 LEDs per metre and 55–65 LM/LED is the format designed for these spaces, with each LED cuttable so a display case can be lit to its exact interior length. Where the light must be aimed rather than run continuously, the XP-CX-18 magnetic track light at Ra≥90 supports exhibition and jewellery settings with a 120° beam angle and aluminium-plus-PC construction.

Offices, restaurants and cove lighting

Continuity matters more than colour criticality. The DK3 linear model at 240 LEDs per metre produces an unbroken line in office buildings, restaurants, apartments and interior design schemes, and is published for use in indoor strips and black profiles. See the published applications for office and mixed-use environments where the DK3 format is deployed.

Retail and exhibition accent lighting

Where display layouts change seasonally, aiming flexibility outweighs linear continuity. XP-CX-18 is positioned for retail, shopping malls and exhibition & events, with 30W, 3000 / 4000 / 6000K and a 120° beam angle that works on merchandise walls, jewellery counters and stands.

Hospitality guest areas, aparthotels and restaurants

Hospitality interiors typically need two behaviour modes in one system: neutral white during service and colour atmosphere after hours. The XP-SM smart strip combines RGB with 3000K, 4000K and 6000K white at Ra≥90 and is published for aparthotels, restaurants, hospitality, interior design and architecture. The XP-ZS decorative strip covers the background layer — hotels, restaurants, retail and architectural features — with 60D or 140D per metre.

Project evidence from XPUP LED’s export work

Two reference points are relevant when assessing whether a supplier can carry a multi-format indoor project. For a U.S. lighting brand, XPUP LED has supplied long-term ODM LED strip solutions for three years at 300,000 metres per year, covering product specifications, colour parameters, certification requirements and packaging customization for private-label retail and project supply. On the project side, a German hospitality project covering hotel public areas and architectural facades used 20,000 metres of LED strip lighting, was completed within two years, and has remained in operation for over four years with consistent brightness and colour quality.

Manufacturing and Customization Backing Behind These Five Models

Format comparison only holds if the supplier can deliver the chosen format at project scale. Zhongshan Xiangpai (XPUP) Lighting Technology Co., Ltd. was established in 2012 in Zhongshan, the lighting manufacturing base in Guangdong, China, operates a factory of more than 10,000 m², and reports annual output of 35,000,000 metres of LED strip with six R&D engineers. Roughly 50% of output is exported, with the EU and USA as the primary markets; products hold CE and RoHS certification and are manufactured in accordance with applicable safety, environmental and energy-efficiency standards.

OEM customization covers voltage, logo, power, dimensions, materials, hardware configuration, internal circuit, colour, factory specifications, nameplate and label. ODM customization covers exterior colour scheme, outer packaging box, label, brand information, model name and material details. Published service terms include a minimum order quantity of 2,000 metres, 18–22 day lead time, monthly capacity of 3,000,000 metres, 100% testing, dedicated technical support for OEM programmes, general technical guidance for ODM programmes, and a 2-year standard warranty.

For buyers comparing formats, the practical implication is that the five products above can be sourced, customized and delivered as one specification package instead of four separate supplier relationships — which matters most when a project uses linear, track and strip lighting in the same building.

FAQ

Conclusion: Choose the Format for the Task, Then Validate the Supplier

Full-spectrum linear fixtures, magnetic track lights and smart strips are not competing answers to one question — they answer three different questions. Full-spectrum strip lighting (XP-BD18DC24V-2835-140D-8MM, Ra≥97) exists to render colour accurately on merchandise and exhibits. High-density linear lighting (DK3-DC24V-2835-240D-9.3mm, 240 LEDs per metre) exists to produce a continuous, dot-free line in profiles. Magnetic track lighting (XP-CX-18, 48V, 120°) exists to place aimable accent light where layouts change, while smart and decorative strips (XP-SM-DC24V-5050-10MM and XP-ZS-DC24V-2835-8MM) carry the ambience and background layers of hospitality and retail interiors.

The decision sequence that avoids rework is consistent: define the lighting task, set the CRI floor from the surfaces being lit, fix the 24V or 48V architecture, match LED density and PCB width to the profile, confirm dimming and control against the applicable code, verify the indoor installation conditions, validate a sample, and only then compare commercial terms. Applied in that order, the format question resolves before the quotation stage, and the comparison becomes a specification instead of an argument.
