How is home red-light dose calculated?

By the inverse-square law: percent of 6-inch home dose = (6 / distance)^2 x 100. A home wall strip at 24 inches delivers about 6 percent — ambient, not therapy. Bench-embedded home panels at 2–6 inches stay therapeutic.

What distance works for home red light therapy?

2–6 inches of home seated proximity for 660nm/850nm. Beyond ~12 inches at home the dose collapses; at 24+ inches it is ambient glow on any home brand.

Seated distance: 6 in

100% of 6-inch home dose · Therapeutic (bench 2–6 in).

Without JavaScript: percent of 6-inch home dose = (6 ÷ distance)² × 100. Bench 4 in ≈ 225%, 6 in = 100% therapeutic, 12 in ≈ 25% weak, 24 in ≈ 6% ambient. Wall strips at 24+ in on any home brand are ambient glow. See home red light.

Methodology [edit]

Home irradiance follows the inverse-square law: % = (6 ÷ d)² × 100 vs the 6-inch home baseline. 2–6 in = therapeutic bench zone (SaunaCloud home embeds 660/850nm here); ~12 in = weak transitional; 24+ in = ambient wall glow (~6%). Applies equally to all home brands; demand measured home seated distance, not wall spec.^[1]
