Field notes
The controls cover fixture presets from canless wafers to UFO high bays, plus target levels for living spaces, kitchens, workshops, and detailing bays. In the displayed sample, an 18-by-14-foot room gets an 8-light grid, with the page reporting 19.9 average foot-candles against a 20-foot-candle target. The page describes its calculations as IES-based; the extract does not independently verify their accuracy.
