How to Choose a Red Light Panel: The Checklist

Panel shopping is confusing because every brand leads with a different number. Work through this checklist in order — it filters out the bad options fast.
1. Decide on size first
Size is the biggest price driver and the hardest thing to change later. A small panel covers one body area per session; a half-body panel covers a torso; a full-body panel covers most of you at once. Bigger panels mean shorter, simpler sessions — but also more space, more weight, and a higher price.
Check: measure where the panel will live. Wall-mounting needs a sturdy wall and an outlet nearby; a stand needs floor space. Don't buy a panel you have nowhere to put.
2. Demand a real wavelength list
The brand should publish the wavelength ranges of its LEDs — commonly 630–660nm red and 810–850nm near-infrared. If a brand lists only "red light therapy" with no numbers, move on. Our wavelength guide explains what these numbers describe.
3. Read irradiance claims skeptically
Brands advertise irradiance (mW/cm²) as if it were a horsepower rating, but the number is typically measured at the LED surface — the highest possible reading — and drops fast with distance. You can't verify it at home without lab equipment. So: note whether the brand states its measurement distance (a good sign), then weigh the number alongside warranty length, review volume, and brand transparency rather than treating it as a ranking score.
4. Check the controls
Look for a built-in timer with automatic shutoff, adjustable session lengths, and ideally independent red and near-infrared modes. A remote or app control is a nice-to-have. Skip features you won't use — complexity you ignore is just a failure point.
5. Verify the warranty
Panels contain hundreds of LEDs and power electronics. A multi-year warranty signals the brand expects its hardware to last; a 90-day warranty signals the opposite. Read what the warranty covers — LEDs, power supply, and labor can be covered differently — and check whether support is reachable before you need it.
6. Confirm the eye-safety provisions
The panel should include protective goggles, and you should plan to wear them every session. Never stare directly at the LEDs. If you have a light-sensitivity condition or take medications that increase light sensitivity, talk to your doctor before using any light device.
7. Sanity-check the marketing
Red flags: disease language ("treats," "cures," "heals"), before-and-after photos, claims of FDA clearance on a consumer wellness device, and irradiance numbers with no stated measurement distance. Reputable brands describe their hardware and let the spec sheet do the talking.
8. Compare total cost, not just the sticker
Factor in the stand or mounting hardware (sometimes sold separately), shipping, and whether the warranty requires you to pay return shipping. The cheapest panel with a one-year warranty can cost more than a mid-range panel with a three-year warranty if something fails.
