For a garage or covered service area, compare the ceiling position with the vehicle lanes, parking spaces and pedestrian route. The useful choice is the fixture and layout that illuminate those tasks while leaving enough clearance for the site.
Record the ceiling height, lane and parking dimensions, columns and pedestrian routes.
Compare the selected fixture’s dimensions and mounting details with the existing boxes, wiring access and vehicle clearance.
Compare a proposed layout for shadows and bright spots. Confirm the selected driver and control wiring before keeping an old dimmer.
| Decision | Available choices | Selection check |
|---|---|---|
| Output choice | 40W/6,000 lm; 60W/9,000 lm; 100W/15,000 lm; 120W/18,000 lm listed. | Compare light output, mounting height and layout together. A larger wattage is not a spacing plan or a one-for-one replacement rule. |
| Ceiling and supply | 40W, 60W and 120W manuals list AC100–277V and junction-box mounting. | Check the exact fixture’s dimensions, mounting hardware and supply. Request the specification for the wattage you intend to order. |
| Dimming | 40W, 60W and 120W manuals list 0–10V dimming. | Confirm controller compatibility, control wiring and low-end/full-off behavior. A retained switch or dimmer needs its own compatibility check. |
| Exposure and location | IP65 is documented for the 40W, 60W and 120W models. | Match the actual exposure and installation instructions. For a gas-station project, have the site’s area classification checked before specifying the fixture. |
Send a ceiling plan or photos, mounting height, area dimensions, power supply and the fixtures being replaced. Request a proposed layout and a quote for the model and quantity you need.
Review the 0–10V control concept, then confirm the selected fixture’s driver, dimming range and switching requirements.
