Showcase lighting may already deliver the approved merchandise presentation at full output in a mockup. In the store, the team may also need to dim it in the evening, control it separately from the background lighting, or restore a selected scene at opening time. Define these operations before ordering so the proposed dimming solution can be checked against actual use.<\/p>\n\n\n\n

For dimmable showcase lighting, review the fixtures, drivers or power supplies, dimming modules where used, and control devices as one configuration. Designers, shopfitters and procurement teams need to establish which operations the combination supports, how it behaves at the required low-light settings, and which version the mockup approval covers.<\/p>\n\n\n\n

1. Define the Scenes That Need Dimming<\/h2>\n\n\n\n

Start with the store's operating requirements and list the actions staff need to perform. One jewelry cabinet may only need independent brightness adjustment. A window display may need scene changes coordinated with its background lighting. Both can be described as dimmable, while requiring different control arrangements.<\/p>\n\n\n\n

\n\n\n\n\n\n\n
Use scenario<\/th>\nOperation to specify<\/th>\nWhat to review in the mockup<\/th>\n<\/tr>\n<\/thead>\n
Normal trading<\/td>\nAdjust the whole cabinet, or control merchandise and background lighting separately<\/td>\nWhether each zone responds as intended and the merchandise remains the visual focus<\/td>\n<\/tr>\n
Evening or low-light display<\/td>\nReduce output to the low-light state required by the project<\/td>\nWhether that state can be maintained and the lighting can be raised from it<\/td>\n<\/tr>\n
Closing and reopening<\/td>\nSwitch off completely, then enter the specified operating state<\/td>\nWhether switching off, restarting and scene restoration meet the brief<\/td>\n<\/tr>\n
A new merchandising theme<\/td>\nAdjust settings manually or recall saved settings<\/td>\nWhether scenes can be recalled repeatedly and which zones need adjustment<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n

Specify brightness adjustment and color temperature adjustment separately. If the white light also needs to move between warm and cool settings, confirm the color-control function, operating method and supported equipment combination. Our existing tunable white light guide panel article<\/a> discusses these requirements for illuminated display backgrounds.<\/p>\n\n\n\n

Identify the operating interface as well: a knob inside the cabinet, a wall panel, an interface used by store staff, or the store's wider lighting control system. Who operates the lighting, which fixtures they control, and what they need to do provide the basis for selecting a solution.<\/p>\n\n\n\n

2. Match the Fixture, Driver and Load Information<\/h2>\n\n\n\n

Send the supplier the fixture model and configuration, and ask them to confirm that the fixture's input requirements match the driver's output. Check wattage, voltage, current, constant voltage or constant current requirements, and the permitted load range and connection arrangement for the selected model.<\/p>\n\n\n\n

MEAN WELL's dimming selection guidance<\/a> similarly starts with the fixture's wattage, voltage, current and constant voltage or constant current requirements when identifying suitable drivers. A compatible dimming function is then selected from that suitable range.<\/p>\n\n\n\n

For a showcase with several shelves, record the fixture quantity, linear light lengths and configuration in each control zone. Explain whether installation will take place in stages or some illuminated shelves may later be removed. If the mockup uses a different fixture quantity from the order, ask the supplier which findings still apply and which operating states need another review.<\/p>\n\n\n\n

Include separate dimming modules, control interfaces or gateways where the project uses them. The supplier and the project's electrical professional should confirm the connection diagram and applicable conditions together, so the fixture schedule can be matched to the control equipment schedule.<\/p>\n\n\n\n

3. Confirm the Specific Control Devices and Functions<\/h2>\n\n\n\n

If the store has already selected a control system, provide the brands, full model numbers, version information and functional requirements for its controllers, panels and relevant interfaces. Keep the driver's full model number and option identifiers so both teams can check the selected version.<\/p>\n\n\n\n

Descriptions such as "supports DALI" or "supports 0\u201310V" identify a control approach. The equipment interfaces and required operations still need confirmation for the project. In the same guidance, MEAN WELL requires the control signal for its three-in-one dimming products to meet the relevant specification. That example does not establish that any controller can be paired with any driver.<\/p>\n\n\n\n

For a DALI project, ask the supplier to identify the selected devices' functions and certification status. Devices described as DALI-2 certified can be checked by model in the official product database; the DALI Alliance's certification overview<\/a> provides the lookup information. Continue to confirm the zoning, scenes and any color-control functions the project requires.<\/p>\n\n\n\n

Before reviewing the mockup, agree on the following:<\/p>\n\n\n\n
