RedTherapy Materials Guide 2026: What's Inside a RedRush PULSE Panel
Turn a RedRush panel around and it stops looking like a lamp. There are fan grilles, a carry handle molded into the frame, threaded mounting points and a power inlet. Flip it back and you're looking at rows of small glass lenses, each one sitting over a single LED, with a little digital display and four buttons at the top.
That hardware is what you're actually paying for, so it's worth knowing what each part is and why it's there. Olivia Reviews read RedTherapy's product listings and the March 2026 manuals on October 20, 2026 and took the RedRush PULSE panels apart, on paper, layer by layer. Everything below is how the brand describes its own components; we haven't opened, measured or tested a panel.
Quick take: A RedRush PULSE panel is built from 3-watt LEDs split between 660nm red and 850nm near-infrared, glass lenses over every LED, custom LED drivers, an iron-based internal shielding cage, two or four cooling fans, and a mounting system that takes a door hook, wall screws, a VESA bracket or a floor stand. The 400 PULSE ($675 when we checked) and 840 PULSE ($1,195) share every component; the 840 simply has more of them. See today's RedTherapy deals before you choose a size.
Layer 1: The LEDs
Every RedRush PULSE panel uses the same building block: a 3-watt LED. What changes between models is how many of them there are.
- RedRush 400 PULSE: 133 LEDs, listed as 67 at 660nm (red) and 66 at 850nm (near-infrared). Power rating: 399 watts.
- RedRush 840 PULSE: 280 LEDs, split evenly at 140 red and 140 near-infrared. Power rating: 840 watts.
Why the split matters in daily use: the red and near-infrared LEDs are switched separately, from two different buttons. And because near-infrared light isn't visible to the human eye, the manual points out that with both channels on, it can look as though only half the panel is lit. Nothing is broken. It also means you can run the near-infrared channel alone when you don't want the whole room glowing red while someone else watches TV.
RedTherapy lists a rated LED lifetime of 50,000 hours for both models. That's the brand's own rating rather than an independent figure, but it tells you the LEDs are meant to last for years of short daily sessions.
Layer 2: The Glass Lenses
Look closely at a RedRush and each LED sits under its own small lens. RedTherapy says these are glass, and that it upgraded "the clarity and quality of the glass lenses for more powerful and even light coverage." The Dual listing calls them "optical lens grade glass."
Lenses shape how the light spreads from each LED, which is why the brand publishes irradiance numbers at several distances rather than a single figure. These are RedTherapy's own measurements:
| Distance | 400 PULSE (brand figure) | 840 PULSE (brand figure) |
|---|---|---|
| Listed maximum | 250 mW/cm² | over 250 mW/cm² |
| 6 inches | 160 mW/cm² | 160 mW/cm² |
| 18 inches | 85 mW/cm² | 90 mW/cm² |
| 36 inches | 32 mW/cm² | 50 mW/cm² |
The practical takeaway: up close, the two panels are listed the same; further back, the bigger 840 holds more of its output, which fits its larger listed coverage area (up to 24" × 84" against the 400's 24" × 42").
Layer 3: The Drivers and the Pulse Electronics
Behind the LEDs sit what RedTherapy calls "custom LED drivers," the electronics that feed power to each LED. On the PULSE panels they also handle the pulsing. Tap the N button repeatedly and the near-infrared channel cycles through four settings: continuous, 10Hz, 20Hz and 40Hz. The R button turns the red LEDs on; the manual warns they're very bright.
The rest of the control strip is simple. Press power and the screen lights up, set your session time with plus and minus, and the timer counts down on its own and switches the lights off at zero, so you can close your eyes behind the glasses and stop watching the clock.
One thing worth knowing if anyone in your home is sensitive to flashing light: the manual carries a strobe and flashing-light warning, and RedTherapy's FAQ asks people with epilepsy or a seizure history to be cautious, because the pulse modes flash.
Layer 4: The Iron Shielding Cage
This is the component RedTherapy talks about most. Inside the housing is what the brand describes as an "iron based internal EMF blocking cage," and it lists an EMF reading of 0.0uT at 6 inches for both panels. The brand even invites owners with an EMF meter to check for themselves.
The FAQ connects this to one specific group: for people with a pacemaker or another implanted electronic device, it suggests talking to their doctor or the device maker first, considering a shielded model like the PULSE panels, and using the panel from 24 inches or more. Olivia Reviews hasn't measured the shielding; the figure is the brand's.

Layer 5: Cooling Fans and the Housing
Hundreds of watts of LEDs make heat, so both panels carry built-in cooling fans: two on the 400 PULSE, four on the 840 PULSE. They sit on the back of the housing, next to the carry handle and mounting points, so leave them room to breathe when you choose a spot.
The housing itself has what RedTherapy describes as "new curved edges and minimalist styling" so it looks at home in a living space or a gym, plus a built-in handle for carrying it room to room. Sizes and weights, as listed:
- 400 PULSE: 9.2" wide × 23" tall × 3.5" thick, 13 lbs.
- 840 PULSE: 10.25" wide × 38.5" tall × 3.5" thick, 22 lbs.
Both run on 100–240V. The homepage says all units are quality checked in the USA.
Layer 6: The Mounting Hardware
The box contents are where the RedRush shows how it's meant to live. Each single panel ships with:
| Part | 400 PULSE | 840 PULSE | What it's for |
|---|---|---|---|
| Hanging wire with carabiners | 1 | 1 | The steel cable that clips to the panel's top hooks |
| Door hanging hook | 1 | 1 | Sits over the top of a door |
| Adjustable rope | 1 | 1 | The pulley that sets the panel's height |
| Wall anchors with screws | 2 | 4 | Wall hanging; the manual says self-tapping anchors are now included |
| Power cord | 1 | 1 | 100–240V |
| Darkened glasses | 1 pair | 1 pair | Recommended for every session |
On the back you'll also find VESA-compatible mounting points, so a standard bracket can work, plus an upper and a lower mounting point. For the optional floor stands, the manual uses M4 × 12mm screws and washers and is firm on one detail: use the upper mounting point, because it's much more stable.
The stands are sold separately for single panels: the Pulse Stand PRO ($74.50) for the 400 PULSE, and the Pulse Stand XL ($97.50) for the 840 PULSE, which also fits the 400. Neither fits older RedRush 360 or 720 models. The RedRush 840 PULSE Dual ($2,490) comes with two quick-release floor stands. Pricing a full setup? Check current RedTherapy offers first.
How the Materials Shape Care
Knowing what's inside explains the brand's care rules. Electronics, fans and glass don't mix with water, so the manual lists the panel as indoor use only and not waterproof. To clean it, switch it off, unplug it and wipe it with a clean, soft, lint-free cloth that's slightly damp. Never open the housing: that voids the 2-year warranty, which covers manufacturing defects but not damage from high moisture, water, power surges, falls, dust build-up or user modifications.
Which Build Fits You?
- Choose the 400 PULSE if you want the full set of components in the lightest frame: 133 LEDs, two fans, 13 pounds, door-ready out of the box.
- Choose the 840 PULSE if you want more LEDs and more of the brand's listed output at a distance, and you have a sturdy door, wall or stand for 22 pounds.
- Choose the Dual if you want two 840 PULSE panels with the stands already included.
Before You Buy
PULSE listings currently show an estimated 10–15 day shipping lead time instead of the usual 24 hours. Shipping is free on the product pages and limited to US states and outlying territories. The 60-day trial counts from the date of purchase on the return-policy page, return postage is the customer's cost, and panels must come back with every accessory in the original packaging. New customers can try the code the site itself displays, WELCOME50, for $50 off a first purchase; for anything newer, see the RedTherapy coupon page.
RedTherapy's FAQ also asks anyone who is pregnant, light-sensitive, has an eye condition or takes light-sensitizing medication to speak with a doctor before using a light device. This isn't medical advice.
FAQ
Are the lenses glass or plastic?
Glass, according to RedTherapy, which describes them as upgraded, optical-grade glass lenses.
Why does a RedRush have fans?
To cool the LEDs and electronics. The 400 PULSE has two fans and the 840 PULSE has four.
Can I use my own wall bracket?
The panels have VESA-compatible mounting points on the back, so a standard VESA bracket is an option alongside the included door and wall hardware.
Do the 400 and 840 use different LEDs?
No. Both use 3W LEDs at 660nm and 850nm; the 840 has 280 of them against the 400's 133.
Final Verdict
Strip a RedRush PULSE down and it's a clear, well-documented build: 3W LEDs in two wavelengths, glass lenses, custom drivers with four pulse settings, an iron shielding cage, fans, and hardware for almost any wall, door or stand. Pick the size by how much of that hardware your space can hold, keep it dry and closed, and let the 50,000-hour LED rating and 2-year warranty do the rest.
