Product Description

Product Details

Product Construction

The finished unit groups its internal working parts inside one assembled body.

Selection & Installation Notes

Choose one version by available space and supply conditions, then check the supporting substrate, required accessories and maintenance access.

Recommended Application

Applications

  • Hotel And Apartment Corridors: Surface mounting avoids a recessed cutout; microwave sensing or emergency operation is specified where the project requires it.
  • Lobbies And Shared Residential Areas: Round and square housings provide two ceiling appearances, with size and power selected from the lighting layout.
  • Offices And Meeting Rooms: CCT and any dimming package should be matched to the driver, controls and intended visual environment.
  • Indoor Retail And Service Areas: The IP54 build addresses defined dust and splash exposure, but it should not be treated as a wet-location, washdown or permanently outdoor rating.

Frequently Asked Questions?

Find clear answers to common questions about product specifications, model selection, applications, and quotation requirements. For project-specific needs, send us your target market, required quantity, and key specifications.

What is the difference between HY04R and HY04S?

HY04R uses a round housing and HY04S uses a square housing. Both shapes are listed in 15, 18 and 24 W versions with corresponding 220, 280 and 330 mm nominal face sizes.

How do I choose the HY04 size and power?

Start with the available ceiling area and lighting layout, then select the matched size-power step: 220 mm at 15 W, 280 mm at 18 W or 330 mm at 24 W. Confirm the required lumen target and spacing before the sample is approved.

Is HY04 recessed or surface-mounted?

HY04 is surface-mounted. It fixes to the ceiling through its rear mounting interface rather than being inserted into a recessed cutout. Check the fixing surface, cable entry and junction space for the intended installation.

Are microwave sensing, emergency and dimming standard on every model?

No. The official product information lists them as available project functions but does not map every function to every model. Specify the required model and function package so the matching driver and controls can be confirmed before sampling.

Where can an IP54 HY04 be used?

IP54 supports indoor installations with defined dust and splash exposure when the approved assembly is installed correctly. It does not by itself make the luminaire suitable for washdown areas, permanent outdoor exposure or water immersion.

Which certification marks apply to the HY04 series?

The HY04 series is shown with CB, CE, ErP and RoHS certification marks. For OEM labels and destination-market paperwork, use the applicable certificate number and model list for the selected configuration.
