Free lighting tools
Make a plan, not a guess.
These lightweight tools help you organize design choices and compare lamp ratings. They do not calculate regulated illuminance, electrical loading or code compliance.
Room lighting planner
Choose a room, its main activity, and the visual atmosphere. Get a three-layer starting plan you can test before purchasing anything.
LED label comparison calculator
Enter a lamp’s rated lumens and watts, plus daily operating hours. Compare nominal efficacy and approximate annual electricity use.
Safety note: Do not treat these outputs as electrical or building-code advice. Bulb, fixture, dimmer, voltage, wiring, and wet-location compatibility require product-specific and local requirements.
