Wrap your lower back in warmth — and keep going with your day.
7HW EmberWrap closes around your waist and puts 54 red and near-infrared LEDs, PEMF, TENS and about 3 lbs of heated natural crystals directly on your lower back and belly. Relief that stays in place while you sit, read or work.
For the ache that sits right in your lower back
No lying down, no holding a pad in place. Wrap it on and get on with your day.
Lower back that tightens up
Wrap it on at your desk and let warmth and light work while you do.
Cramps & belly discomfort
Turn it round to rest on your belly for soothing, steady warmth.
Lower back that feels strained
Gardening, moving boxes or the gym — wrap up afterwards and unwind.
Back that won't settle
Sit back on the sofa with it on and let the day ease out of your lower back.
Everything working together where it aches
Red & near-infrared light, concentrated where it aches
54 LEDs — 26 at 660nm red and 28 at 850nm near-infrared — are packed into the centre panel that rests on your lower back. More than half are near-infrared, the wavelength that reaches deeper toward muscles.
- 26 × 660nm red LEDs
- 28 × 850nm near-infrared LEDs
- Densest light zone sits right on your lower back
Gentle PEMF pulses you can tune to your day
Pulsed electromagnetic fields work quietly around your waist — no buzzing, no pressure. Choose a lower frequency to wind down, or a higher one for a refreshed start.
- Adjustable range from 3 to 64 Hz
- Silent and gentle — felt as calm, not shocks
- Works at the same time as heat and light
TENS for tight, knotted muscles
TENS (transcutaneous electrical nerve stimulation) sends mild electrical pulses that you feel as a gentle tingling. It's a popular drug-free way to ease lower back tension — and it adds an active feel to every session.
- TENS function included
- Felt as a light tingling, not a shock
- Start gently and build up as you get used to it
About 3 lbs of heated natural crystals
Roughly 3 lbs (±5%) of natural crystals from 7 mixed gemstones hold and spread heat evenly, so the warmth feels deep and steady — not the hot-spot sting of a regular heating pad.
- ≈3 lbs natural crystals (±5%)
- 7 mixed gemstones in a chakra design
- Contoured panel that follows the curve of your lower back
Your heat, your way — held steady by remote
Set the warmth you like from 30 to 70°C (85–159°F) and the smart constant-temperature control keeps it there. Add a timer from 1 to 12 hours and simply relax.
- Smart constant-temperature remote control
- 30–70°C / 85–159°F adjustable heat
- 1–12 hour timer
Seven gemstones, seven bands of colour
The 7 mixed gemstones sit in colour bands across the centre panel — the part that rests against your lower back.
Made to wrap, made to move
Fits around your waist
At 10 × 55 in, it wraps around the waist with an adjustable hook-and-loop closure, so it stays in place.
Snug, secure weight
Heavy enough to sit firmly against your back, light enough to wear while you sit and work.
Wipe clean in seconds
Soft PU leather with bound-edge stitching resists fraying and wipes clean easily.
Simple to run
One remote for temperature, timer and settings. Wrap, press, done.
Four shapes, one system — use them together
Every Ember piece shares the same red light, PEMF, TENS, heated crystals and smart remote. Pick the shape for each part of your day, or combine them.
80 × 190 cm · 156 LEDs. Lie down and treat everything at once.

Three steps to your first session
Wrap it on
Place the light panel on your lower back or belly and fasten the hook-and-loop closure.

Questions before you buy
Yes — that's what EmberWrap is built for. It fastens around your waist, so heat, 54 red and near-infrared LEDs, PEMF and TENS stay on your lower back while you sit, read or work. Most people use it for 20–40 minutes at a time.
Yes. Simply turn it round so the light panel rests on your belly. Many people find steady warmth soothing during their period. Keep the heat at a comfortable level.
At 140 cm (55 in) long with an adjustable hook-and-loop closure, it fits most adult waists.
That's normal. Red light (660nm) glows clearly, but near-infrared light (850nm) is almost invisible to the human eye. Those points are working even when they look dim or dark.
TENS feels like a light tingling or gentle pulsing under the skin — not a shock. Start at the gentlest setting and increase slowly until it feels comfortable. You can enjoy the heat, light and PEMF on their own whenever you prefer.
For the best light contact, use it with bare skin or thin clothing. Thick fabric blocks most of the light, though you'll still feel the heat and PEMF.
You set the temperature anywhere from 30 to 70°C (85–159°F) on the remote, and the smart constant-temperature control holds it steady. Start at a lower setting and increase gradually.
Do not use it if you have a pacemaker or other implanted electronic device, epilepsy, or if you are pregnant. Never use TENS on the front of the neck, on the chest over the heart, on the head, or on broken or irritated skin. Do not use on your belly during pregnancy. If you have a medical condition, light sensitivity, reduced heat sensitivity or are unsure, check with your doctor first. Learn more in our Wellness Knowledge Hub.
