Which red light device will you actually use? Format, budget and specs

Plenty of red light devices end up in a drawer, or sitting in the corner of the lounge like a neglected houseplant. Not because they’re broken, but because they didn’t fit the way their owner actually lives.

I’m Blake, founder of Grounded Kiwi, our family-owned earthing and wellness store in New Plymouth. My own red light habit is 20 minutes first thing in the morning, and it sticks because it fits my morning. So this post doesn’t pick a device by health goal. It picks by routine, then budget, then the few specs worth reading. Give it five minutes and you should know which format suits you.

Start with your routine, not the device

Three questions, each pointing to a format.

1. Where will you use it?

• On the couch: something you can wear, like a strap, belt, wrap or face mask.
• At a desk or bench: a desktop panel that sits on a flat surface.
• Away from home: a torch, or a portable panel with a battery.

2. Hands-free or held?

Wraps, belts, the mask and the cap are hands-free. The torch and portable panel are held (the portable panel has an optional stand). Desktop panels sit on their own stand, so you just sit in front of them.

3. How long will you realistically sit?

Most of the timers on our devices run somewhere between 5 and 30 minutes. Be honest with yourself here. If a device takes ten minutes to set up, or means sitting somewhere you don’t normally sit, it won’t get used.

What each budget gets you (NZ prices)

All prices are from our product pages at the time of writing.

Under $200: one area at a time

• Red Light & Heat Massage Strap, $117. 36 LEDs (660–850nm), cordless with a 3,000mAh battery, plus heat and vibration. CE, FCC and RoHS certified per its page.
• Red Light Therapy Torch, $169.99. Three 3W LEDs at 630, 660 and 850nm, rechargeable, with a 5-minute auto shut-off. For small, targeted areas.
• Body Wrap & Wellness Belt, $199. 72 triple-core LEDs (660 and 850nm), a 31.5 × 16cm pad, USB or power bank, and a 20, 30 or 45-minute timer.
• Joint Wrap, $199. 192 LEDs (660 and 850nm), 77 × 29.8cm, 10W USB, 20-minute auto timer.

My tip in this band: the joint wrap is really handy to have in the house. You never know when you’ll want it, and when you do, it’s there in the cupboard, ready to strap on.

$200 to $500: a bigger area, or a dedicated face or scalp device

• Red Light Therapy Cap, $289.99. 96 LEDs (660 and 850nm), cordless, 5 to 30-minute timer, 12-month warranty.
• Red Light Therapy Face Mask, $299. Red at 620–630nm plus six other colour modes, a 5, 10, 15 or 20-minute timer, and a 2,000mAh battery with USB-C charging.
• Portable Panel, $409 ($459 with stand). 12 × 5W LEDs (660 and 850nm), battery-powered with USB-C, built-in timer, 1-year warranty.
• Compact Desktop Panel (RP300), $459.99. 60 LEDs (30 × 660nm, 30 × 850nm), mains-powered, built-in timer, protective eyewear included, 1-year warranty.
• Full-Back Wrap, $489.50. A 95 × 67cm T-shaped wrap for the neck, shoulders and back, with 395 triple-chip modules (660 and 850nm), a 10, 20 or 30-minute timer, a mains adapter and a wipe-clean inner surface.

Around $1,000: one panel that does more

• Pro 8-Wavelength Tabletop Panel, $989.99. 72 × 5W dual-chip LEDs, eight wavelengths (630, 650, 660, 670, 810, 830, 850 and 1060nm), app control, adjustable pulse from 1 to 10,000Hz, a stand, and a 2-year warranty. It weighs 6kg, so it’s a stay-put panel.

Our Full Body Red Light Therapy Mat sits above this band. It’s out of stock at the moment but should be back in stock soon.

More power and more features aren’t automatically more benefit. Spend on the format you’ll use, not the biggest number. (There are specialist devices in the range too, but they’re outside the “first device” decision.)

A wearable belt suits the couch: strap it on, set the timer, carry on with your evening.

The four specs worth reading

Wavelengths

Most at-home devices, and much of the research, use red light in the 630–670nm range and near-infrared around 810–850nm. Extra wavelengths on the box haven’t been shown to do more. The Pro panel has eight, including 1060nm, which is fine, but I’d buy it for the panel itself (its size, the app, the stand) rather than for the wavelength count.

Irradiance, at a stated distance

Irradiance is the light power reaching your skin, usually given in mW/cm². It only means something with a distance next to it, because the light spreads out as you move back. The RP300’s page gives it properly: more than 110 mW/cm² at 7.5cm, with a suggested sitting distance of 7.5 to 30cm. Further away means less light. If a device quotes a number with no distance, treat it as a headline figure rather than something you can compare.

True power, not “rated” watts

The RP300 is listed as “300W rated” with a true power draw of about 90W (±5%), per its product page. Rated figures usually come from adding up the LEDs’ nominal ratings, while the true figure is what the panel actually draws from the wall. Both are on the page, which is how it should be. Be wary of any panel that only gives you the big number.

Timer, power source and warranty

A built-in timer makes the habit easier, because you don’t have to watch the clock. Battery means you can use it anywhere; mains means you never have to remember to charge it. And check the warranty is in writing. On the product pages, the portable panel and RP300 have 1 year, the cap 12 months, and the Pro 2 years. Where a product page doesn’t state its own term, our refund policy gives 12 months. Local stock and a seller you can actually reach matter just as much.

The RP300 lists its irradiance with a distance and its true power draw next to the rated figure.

Session length (the short version)

Use the device’s own timer as your guide. For most of the devices above, that means somewhere between 5 and 20 minutes, and up to 30 or 45 on some wearables. Short sessions you’ll actually keep doing beat the occasional marathon. If you want the longer explanation of dose and distance, it’s in Is 10 minutes of red light therapy enough?

“Medical grade”, FDA and certifications: what they mean in NZ

You’ll see “medical grade” and “FDA cleared” a lot. FDA clearance is a United States process for specific uses. “Medical grade” isn’t a defined consumer term here, so on its own it tells you very little.

The devices in our range are home wellness devices, and several product pages (including the torch, belt and RP300) say plainly that they’re not medical devices. More useful things to check on any device: published wavelengths, irradiance with a distance, safety markings where they’re listed (the strap, joint wrap and mask pages list CE, FCC and RoHS), a proper NZ/AU plug or adapter on anything mains-powered, and a seller who’ll sort out a fault.

Eyes and sensible use

• For panels near your face, close your eyes or wear the eyewear supplied. The RP300 comes with protective eyewear.
• Don’t stare into the LEDs, on any device.
• If you take light-sensitive (photosensitising) medication, are pregnant, or have a skin or eye condition, check with your GP before you start. Several of the product pages say the same.
• If your skin feels uncomfortably hot or irritated, stop, or move further back.

A mask is hands-free and made for the face. Handy if that’s where you want to use it.

If you just want a starting point

Here’s how the formats line up with the most common routines:

• Something for the couch: the strap ($117) or the belt ($199).
• Mostly your face: the mask ($299). Our post on red light and wrinkled skin has more on that.
• A set-up at a desk or bench: the RP300 ($459.99).
• Something to keep in the cupboard for when you need it: the joint wrap ($199).
• Travel: the torch ($169.99) or the portable panel.
• You’ve used red light for a while and want one panel to do more: the Pro ($989.99).

If you’d rather compare by body area, our post on the best red light therapy device in New Zealand does it that way, and wrap vs panel after a physical day covers one specific use.

Quick FAQ

Should I get a mask or a panel?
If it’s mainly for your face and you want to stay hands-free on the couch, a mask. If you want to use it on more than your face, or you’ll happily sit at a desk for a session, a panel.

Is paying extra for 1060nm or “8 wavelengths” worth it?
Not for the wavelength count alone. Red around 630–670nm and near-infrared around 810–850nm are the common ones. Buy a multi-wavelength panel if you want the panel for other reasons.

What does irradiance mean?
How much light power reaches your skin, in mW/cm². It’s only meaningful with the distance it was measured at, because it drops as you move back.

Battery or plug-in?
Battery if you’ll move it around or travel with it. Mains if it’ll live in one spot and you’d rather not think about charging.

Do I need a “medical grade” device?
Not for home wellness use. Look for published wavelengths, irradiance with a distance, safety markings, and a warranty from a seller you can reach.

How long are sessions?
Follow the device’s timer, usually 5 to 20 minutes, and stay consistent. My own is 20 minutes in the morning.

Is it worth buying a device rather than going to a clinic?
We’ve done the cost maths in is it worth buying a red light therapy device?

Buy the one you’ll use

Pick the format that fits a routine you already have, use it most days on the built-in timer, and judge it over a couple of months rather than a couple of nights. You can compare the whole red light therapy range, read our complete guide to red light therapy for background, or see how I fit mine in, in red light in the morning, grounding mat at night.

And if you want something that does its job without you thinking about it at all, that’s the grounding mat for bed. Still unsure? Our FAQ page covers the basics, or get in touch and we’ll talk it through, no hard sell.

Wellness note: This is general information, not medical advice. Red light devices are wellness products, not treatments or cures. If you have a medical condition, take photosensitising medication or are pregnant, talk to your GP before using red light.

Happy Earthing,
