Laser therapy has gone from “something the rehab clinic has” to something a lot of serious owners and therapists are buying for themselves. But it’s also an area where the marketing can blur an important line — and that line is about safety. A pocket-sized “cold laser” pen and a powerful clinical torch are not the same class of device, even though both get called “laser therapy.”
So before you spend, here’s a clear, honest guide to what laser therapy is, how the units in our range genuinely differ, and how to choose the right one without getting hurt or sold more than you need.
What laser therapy is
Therapy lasers deliver red and near-infrared light into tissue. The proper name is photobiomodulation (you’ll also see “PBM,” “low-level laser therapy/LLLT” and “cold laser”). The established science is that this light is absorbed by the energy-producing parts of cells, which is used to support reduced inflammation, comfort and tissue recovery — drug-free and non-invasive. It’s used by vets and therapists for things like joint comfort, soft-tissue and post-operative recovery, and acupuncture or trigger-point work.
It works through light, not heat, when correctly dosed — and getting the dose right matters more than chasing the biggest number on the box. As with everything we sell, it supports veterinary care; it doesn’t replace it, and it isn’t a cure for any condition.
The big distinction: “cold laser” vs Class-4
This is the part to read twice, because it’s where most confusion (and most risk) lives.
- A true “cold laser” is a low-level (Class 3B) device — half a watt or less. Our 0.5W laser acupuncture pen is this kind of unit: a pinpoint tool, ideal for acupuncture and trigger points and small, shallow targets.
- The higher-powered torches — 1.5W, 3W, 5W and 8W — are powerful Class-4 lasers. More output lets you treat larger and deeper areas and deliver a given dose faster. But that power is exactly why they demand respect.
Here’s the honest bit the marketing often skips: it’s fine to call the little pen a “cold laser” that won’t burn at the correct dose, but you must not carry “no side effects, won’t burn” language onto the powerful units. A Class-4 laser can cause thermal warming or burns if mis-used, and it can damage eyes. These are professional-grade tools, not harmless gadgets — so treat them that way.
Eye safety is non-negotiable
With any Class 3B or Class 4 laser, eye protection isn’t optional:
- Never aim at or near the eyes, and never look into the beam.
- Wear proper laser-rated goggles — ordinary sunglasses do not protect you, and a retinal injury can be permanent.
- Your animal can’t wear goggles, so shield their eyes too (animal goggles or a cover). Everyone in the room should be eye-safe.
- On the powerful units, keep the beam moving, dose correctly, and take extra care over dark coats (which absorb more energy and warm faster).
How to choose by use-case
Forget “which is best” — the right question is how big is the area, how deep is the target, and how often will you treat?
- Pinpoint and acupuncture/trigger points, small shallow spots: the 0.5W pen or the focal 1.5W torch.
- A versatile single device for both shallow and deep, across many situations: the dual-wavelength 5W laser torch is our most popular for exactly this reason — it handles surface and deeper targets in one tool.
- Large muscle groups, deeper targets, horses, or a busy caseload where speed matters: step up to the higher-powered units.
More watts isn’t a different kind of therapy — it’s the right dose delivered faster over bigger or deeper areas. Browse the full laser therapy range to compare, and if you’re matching a device to specific work, talk to us or your vet/therapist first.
Frequently asked questions
Is a Class-4 laser safe to use at home?
It can be used safely, but only with proper eye protection, correct technique and an understanding of where not to use it (over eyes, tumours, the pregnant uterus, or the growth plates of young animals). If you’re new to it, get training or work under your vet or therapist.
Do I need to shave my dog or horse?
No — the light passes through coat. On very dark coats, dose more conservatively and keep the beam moving, as dark hair absorbs more energy and warms faster.
How many sessions before I notice anything?
It varies with the situation; therapists often work through a short series of sessions and then space them out. Your vet or therapist can guide a sensible plan.
