Frequently Asked Questions
Foot-candles measure brightness. For ambient lighting, 20-30 fc is typical. For task areas like kitchens, aim for 50 fc. Use lower values for bedrooms (10-20 fc).
Beam angle affects light spread. Narrow angles (25-40°) focus light, while wide angles (60-120°) spread it. The calculator uses beam angle to adjust effective lumens.
Yes, this calculator works for any recessed light type. Just input the lumen output per light (typically 600-1500 lm for LEDs).
We round up to ensure you have enough light. You can always dim lights or use fewer if you prefer slightly dimmer conditions.
