The HUIHENG H-LB017 is a recessed LED downlight series designed for commercial lighting applications, including retail spaces, hotels, restaurants and offices. The published series specifications list 20W, 25W, 30W and 40W options, an 80° beam angle, CRI ≥90, selectable 3000K, 4000K and 5000K color temperatures, IP65 protection and luminous efficacy of up to 120 lm/W. HUIHENG states that datasheets, IES files and project-specific lighting layout suggestions are available on request. Buyers should confirm the specifications of the exact model and configuration before ordering.

H-LB017 Product Specifications

Dimension and cut-out reference. Verify all dimensions against the current official datasheet.

Designed for Clean, Minimal Commercial Interiors

The H-LB017 uses a fixed recessed design with sand white and sand black finish options. Its recessed form is intended to integrate with the ceiling rather than become a prominent decorative feature. With an 80° wide-flood beam angle, it can contribute to general ambient lighting in suitable layouts. The final result depends on ceiling height, fixture spacing, room geometry, surface reflectance and the lighting design.

Product detail and construction overview for the H-LB017 series.

CRI ≥90 for Color-Critical Applications

The H-LB017 series is specified with a color rendering index (CRI) of ≥90 and CCT options of 3000K, 4000K and 5000K. Higher color rendering can be useful in retail displays, showrooms, hospitality spaces and other interiors where the appearance of merchandise, finishes and furnishings matters. Select the color temperature according to the project brief and confirm the available combination for the chosen model.

IP65 Protection: Check the Installation Conditions

The product article specifies IP65 protection for the H-LB017 series. Before specifying the luminaire, confirm the rating on the datasheet for the exact configuration and check whether the intended ceiling location, exposure and local installation requirements are compatible with the product. An IP rating alone does not establish suitability for every wet, outdoor or specialist environment.

Power, Cut-Out Sizes and Installation Planning

The H-LB017 series lists 20W, 25W, 30W and 40W power options, together with four cut-out sizes: Ø120 mm, Ø145 mm, Ø175 mm and Ø195 mm. These options may help project teams compare configurations for different ceiling layouts. Do not select a model by wattage alone: check luminous flux, ceiling height, fixture spacing, target illuminance, beam distribution, ceiling construction and any applicable local lighting requirements. Confirm the exact cut-out dimension and installation clearance using the manufacturer's technical drawing before cutting the ceiling.

Use IES Files to Support Lighting Design

IES photometric files can be used by lighting designers to model a luminaire's light distribution in compatible lighting-design software. HUIHENG states that IES files and project-specific layout suggestions are available for the H-LB017 series. Ask for the file that matches the exact wattage, CCT, optic and driver configuration being considered, then evaluate illuminance, uniformity, mounting height and fixture spacing for the project.

Photometric Data: Confirm the Conditions Before Use

The original product article cites a 40W example at a 5 m mounting height, with a reported central illuminance of 2575 lx and a light-spot diameter of 8.25 m at 4000K. These figures should only be used in project decisions after the manufacturer confirms the calculation or measurement method, measurement plane, photometric file, and the definition of the stated light-spot diameter. Request the supporting photometric report or simulation before using the figures in a specification or tender.

Applications in Retail, Hospitality and Office Projects

Depending on the confirmed configuration and lighting design, the H-LB017 may be considered for retail areas, showrooms, hotel interiors, restaurants and office spaces. The final fixture selection should account for the task being illuminated, ceiling height, visual comfort, required illuminance, maintenance access and the project's electrical and building requirements. For project-specific recommendations, provide the reflected ceiling plan, room dimensions, ceiling height and target lighting criteria.

OEM/ODM and Project Support

HUIHENG states that it supports OEM and ODM customization and can provide product datasheets, IES files and lighting layout suggestions. Buyers should confirm the available customization scope, minimum order quantity, sample process, production lead time, warranty terms, compliance documentation and packaging requirements directly with the factory. These details can vary by configuration and order.

Frequently Asked Questions

What is the HUIHENG H-LB017 recessed LED downlight?

The H-LB017 is a recessed LED downlight series for commercial lighting applications. The published specifications list multiple power and cut-out options. Confirm the exact configuration against the manufacturer's datasheet before ordering.

What does CRI ≥90 mean for a commercial downlight?

CRI ≥90 indicates a high color-rendering level under the relevant measurement method. It can be useful in retail, showroom and hospitality environments where the appearance of products and interior finishes is important. Confirm the specification for the selected model.

How should I choose downlight wattage for a high ceiling?

Wattage alone cannot determine the correct choice. Consider luminous flux, mounting height, beam angle, fixture spacing, room reflectance and target illuminance. Use the matching IES file in a lighting simulation to assess the proposed layout.

Can the H-LB017 be used where IP65 protection is required?

The product article specifies IP65 for the H-LB017 series. Confirm the rating for the exact configuration and check the intended installation conditions and applicable local requirements before specifying it.

Can HUIHENG provide IES files and datasheets?

HUIHENG states that datasheets and IES files are available on request, along with project-specific lighting layout suggestions. Request documentation matching the exact model and configuration under consideration.

What information should I provide for a project quotation?

Share the project country and type, room or ceiling plan, ceiling height, target illuminance, preferred CCT, estimated quantity, required compliance documents and target delivery schedule. If the specification is not finalized, provide the project drawings for an initial review.
