infrared knee pad

Many pads advertise visible and near‑infrared wavelengths. Commonly listed wavelengths include 660 nm (visible red) and 850 nm (near‑infrared); some listings also mention 880 nm. One product's description shows unusually large "lamp‑chip" figures (listed as 2660 nm and 1850 nm) that appear inconsistent with typical red/NIR therapy specifications — check the product details or manufacturer for confirmation.

Most devices provide multiple adjustable heat levels (several list four heat settings). Documented temperature ranges in product descriptions vary; examples include roughly 103–159 °F on one pad and about 110–140 °F on others. Always verify the specific temperature range for the model you’re considering, since marketing copy and measurement methods can differ.

Common modes and extras include combined red/near‑infrared light plus heat therapy, vibration massage, pulsed or multi‑intensity light modes, built‑in timers, memory settings, and adjustable intensity controls. Models vary, so check the product page for specific mode names and any bundled accessories.
