Irradiance Is The Only Number That Matters

Every red light panel quotes LED count and wattage because those numbers are big and easy to print. Neither tells you what reaches your skin. Irradiance does, measured in milliwatts per square centimetre at a stated distance, and the stated distance is where brands get slippery. A panel quoting a huge figure at 3 inches is telling you almost nothing useful, because nobody stands 3 inches from a panel.

Look for numbers given at 6 and 12 inches. The HG1500 publishes them, which is more than a lot of competitors do, and the dual chip LEDs are the reason it can hold a usable figure across a large panel rather than just in the middle.

Dose, And Why More Is Not Better

Red light has a biphasic response, meaning there is a window where it helps and past that the benefit drops off. More time under the panel does not keep improving things. Ten to fifteen minutes at a sensible distance covers most of what people are chasing. Standing there for 45 minutes is wasted time and possibly counterproductive.

Distance sets the dose as much as time does. Closer is stronger, so if you halve the distance you should cut the time. Most people pick a distance, forget about it, and never think about it again, which is fine as long as the starting point was reasonable.

Living With A Panel This Size

It is big and it is heavy. Door mounting works, a stand works better, and either way you need a spot where you can stand or sit in front of it with clear space. That rules it out for a lot of flats and bedrooms, and its worth measuring before ordering rather than after.

Fans run while it is on and they are audible. Not loud, but you will hear them, and anyone expecting silence will be annoyed. Eye protection comes in the box and you should use it at this output level.

Panel Or Something Smaller

If you are treating a knee or a shoulder, this is far more panel than you need and a wrap costs a fraction. The HG1500 earns its place when you want half or full body exposure in one session, which is the case for people using it for general recovery rather than a specific injury.
