Red and infrared light therapy has become one of the most trusted non-invasive options for pain relief. People use it to improve circulation, ease chronic pain, and recover from sports injuries. In 2025, there are more devices on the market than ever. But not all are the same.
This guide looks at what makes a good device and why HealthLight pads stand out.
What to Look for in a Device
When comparing red and infrared light therapy devices, these factors are the most important:
- Dosage: How much energy is delivered per session.
- Power: Stronger pads usually mean shorter treatment times.
- Proximity: LEDs should sit close to the skin for best results.
- Safety: FDA requires pads to stay below 105°F.
- Design: Some are panels or masks, others are flexible pads.
Device Comparison
Here’s a look at how popular devices compare, using a 20-minute session as the baseline:
- HealthLight Foot & Ankle Pad – 3,040 joules, 122 diodes, max temp 105°F. Battery available.
- Anodyne Freedom – 519 joules, 120 infrared LEDs, runs hotter at 116°F. No battery option.
- Neuropacalm – 2,499 joules, 64 red LEDs, stays cooler at 89°F. Battery available.
- HealthLight 180 Pad – 2,336 joules, 180 LEDs, 105°F. Battery available.
- Inlight 180 – 660 joules, 180 LEDs, no battery option.
- HealthLight 264 Pad – 5,629 joules, 264 LEDs, FDA-compliant surface temp at 105°F.
- Neurocare 264 – 1,238 joules, 264 LEDs, 105°F.
Other models include knee and shoulder wraps, facemasks, and T-pads. HealthLight consistently shows higher joules per session, FDA-compliant heat levels, and U.S. manufacturing.
Why HealthLight Stands Out
Looking at the numbers, HealthLight pads deliver a higher dosage than most competitors. They also meet FDA safety requirements and offer features like pulse randomization, which helps prevent the body from adapting to treatment over time.
All HealthLight pads are:
- FDA-listed
- Manufactured in the USA
- Available with battery options for portability
- Designed to stay under 105°F for safe use
The HealthLight Product Line
HealthLight offers pads in many shapes and sizes to target pain where it’s felt:
- Foot & Ankle (122 diodes)
- Foot & Calf (131 diodes)
- Large Pad (264 diodes)
- Long Pad (180 diodes)
- Neck Pad (208 diodes)
- Medium Pad (132 diodes)
- Small Pad (90 diodes)
- T-Pad (261 diodes)
- Knee & Shoulder Pad (204 diodes)
- Facemask (104 diodes)
Final Thoughts
The market for red and infrared light therapy is crowded in 2025. But if you want a device that’s FDA-listed, easy to use, and made for real pain relief, HealthLight pads are worth considering.
They don’t promise a cure. But they give people a safe, proven way to manage pain and support recovery.
