660nm or 850nm?
The answer depends on depth. 660nm absorbs in skin and scalp. 850nm penetrates to muscle, joint, and brain. Most goals want a mix.
Pick your primary goal. We’ll show the wavelength split, effective penetration depth, and the right Hale panel format. All RLPRO panels ship with an 8-band spectrum — the split is about how you weight your dose, not which panel you buy.
660nm primarily drives fibroblast activation. 850nm penetrates deeper dermis for combined effect — a 70/30 split is the literature consensus for cosmetic protocols.
Effective penetration for your goal: 0.5–2 cm.
All Hale RLPRO panels deliver 8-band coverage (630/650/660/670/810/830/850/1060 nm) — so the split is about which band you weight your dose toward, not which panel you buy.
Deploying RLT into a clinic?
We’ll walk through panel selection, the wavelength evidence behind each indication you treat, and how to position RLT as a high-margin add-on with measured 8–10 week payback.
