Lighting Fixture Schedule Worksheet Chart
Use this worksheet after the calculator result to record fixture type, room, fixture count, lumens, watts, controls, circuit grouping, and photometric follow-up.
Quick reference table
A lighting fixture schedule worksheet is a room-by-room planning record. It does not replace a lumen or foot-candle conversion chart; it keeps fixture count, fixture watts, controls, circuit load, room task, mounting notes, and photometric review together.
Fixture schedule worksheet columns
| Schedule field | Record | Planning use |
|---|---|---|
| Room or zone | Room name, task, area, ceiling height | Keeps target level tied to actual use |
| Fixture type | Type mark, manufacturer, lumen output, watts, CCT, CRI | Links calculator result to product data |
| Count and layout | Fixture count, spacing note, mounting type | Feeds layout and photometric review |
| Controls | Switching, dimming, occupancy, daylight, emergency note | Affects energy and operation |
| Circuit load | Watts, voltage, circuit group, panel note | Routes to lighting-circuit and branch-load checks |
Fixture schedule handoff checks
| Handoff | Keep visible | Why it matters |
|---|---|---|
| Lighting design | Foot-candles, lux, CU, LLF, task plane | Average level must stay tied to assumptions |
| Circuit design | Fixture watts, driver load, voltage, circuit grouping | Fixture count becomes connected load |
| Controls | Dimming type, occupancy, daylight, schedule | Controls can change measured levels and load profile |
| Procurement | Fixture type mark, option, lead time, substitution rule | A quote needs a specific fixture basis |
Formula basis
Connected lighting load = fixture count x watts per fixture. Average illuminance screen = adjusted lumens / area when CU and LLF are documented.
- Fixture count comes from the room or zone count selected after the lighting calculator result.
- Watts per fixture is the product or schedule wattage used for connected-load review.
- Adjusted lumens depend on fixture output, CU, LLF, mounting height, and room assumptions.
- Controls and circuit groups determine how the schedule connects to branch-circuit planning.
Worked examples
Assumptions. Balanced load and line-to-line voltage assumptions behind this chart.
- This worksheet documents fixture scheduling and does not reproduce proprietary lighting tables.
- Fixture selection can change with photometric files, owner standards, product availability, mounting conditions, controls, and field measurements.
- Average illuminance, connected load, and fixture count should be reviewed as separate but linked decisions.
Code and standard notes. Planning limits that should be checked before final equipment selection.
- Use this chart as a field record; verify adopted energy, life-safety, workplace, owner, fixture manufacturer, control-equipment, and AHJ requirements before final fixture selection or circuit loading.
How to use this chart
Worksheet checklist. Record source basis, review gaps, and assumptions before using the chart result.
- Capture room dataWrite room name, area, ceiling height, task plane, target level, and owner criterion.
- Capture fixture dataList type mark, lumens, watts, CCT, CRI, distribution, mounting, control type, and quantity.
- Capture circuit dataRecord total watts, voltage, circuit group, panel note, emergency status, and photometric follow-up.
Common mistakes to avoid. Review these before turning chart current into an equipment decision.
- Using fixture count without recording fixture watts, controls, circuit group, or product basis.
- Treating a foot-candle result as enough by itself for spacing, glare, uniformity, and emergency-lighting needs.
- Allowing product substitutions without checking lumen output, distribution, watts, driver type, mounting, and controls compatibility.
