1. Planning Estimation Only
The calculators, foot-candle heatmaps, wattage estimates, and ceiling blueprints provided by LumenGrid Studio (lightinglayoutcalculator.com) are intended for preliminary architectural and DIY layout visualization only. Actual installed illuminance varies based on manufacturer IES photometric files, paint gloss, furnishings, voltage drop, and dimmer settings.
2. Electrical & Building Code Safety
Always verify branch circuit breaker ratings (NEC 80% continuous load rule), IC (Insulation Contact) and airtight fixture ratings, thermal clearances, and hidden ceiling utilities (wiring, plumbing, HVAC ducts, and structural trusses) with a licensed electrician and local building inspector before cutting or wiring any ceiling.
