Bluetooth app control No complicated button sequences – set power, treatment time and audio signals easily and intuitively via the free Android app. Pain-free, non-invasive Photobiomodulation (PBM) acts at the cellular level – it does not heat or cause pain, and the scientific literature reports no significant side effects when used appropriately. CE 2274 medical certification Certified as a medical device according to EU directives and manufactured to all relevant safety and quality standards – a true diode laser, not a dubious LED lamp. Who is it recommended for? Do you barely bend your knee in the morning and find stairs difficult? Sound familiar? You need 5–10 minutes of movement in the morning before your knee works properly. Going downstairs is almost torture. Knee osteoarthritis and knee joint inflammation are among the most common complaints that impair daily life. Research suggests that 808 nm laser therapy may help reduce joint pain and improve knee function. A 2025 network meta-analysis of 32 RCTs showed that soft-laser therapy is the most effective physical therapy method for reducing pain from knee osteoarthritis (Lan et al., 2025). The L2000 Pro delivers 20 Joules in 10 seconds – precisely the energy needed for treating large joints (knee, hip, shoulder). Is your lower back constantly sore, making even driving painful? Sound familiar? After prolonged sitting it hurts to stand up, and your back constantly reminds you something is wrong. Chronic low back pain is one of the most common conditions reducing work capacity. The 808 nm infrared laser penetrates 3–4 cm into tissues – reaching the deep muscles and ligaments around the spine. Studies indicate that soft-laser therapy can help relieve chronic low back pain. Use the device for 5–10 minutes daily on the painful area – the Bluetooth app lets you easily set the optimal treatment time. Another strain? Two weeks off training again? Sound familiar? You barely warmed up when something twinged in your calf or hamstring. Injuries can sideline you for weeks and you impatiently wait to start again. Scientific studies show that photobiomodulation (PBM) may support tissue regeneration and reduce inflammation in muscle injuries, strains and sprains. The 2000 mW output allows treating larger muscle groups in a short time. Sports physicians and physiotherapists worldwide use Energy Laser devices to help athletes recover faster. Can’t hold a cup because of tennis elbow? Sound familiar? Elbow pain affects almost every action – gripping, holding, lifting, twisting. Tennis elbow (lateral epicondylitis) and golfer’s elbow are stubborn chronic inflammations that can torment for months. A 2025 meta-analysis of 12 RCTs confirmed that soft-laser therapy effectively reduces pain and improves grip strength in tennis elbow (Zhang et al., 2025). Daily 3–5 minute treatments with the L2000 Pro on the painful area typically result in gradual improvement. Do you have a wound that won’t heal for weeks? Sound familiar? Leg ulcers, diabetic wounds, postoperative scars – sometimes the body needs extra help to heal. Hard-to-heal wounds can seriously reduce quality of life. Photobiomodulation research suggests it can support wound healing by stimulating cell proliferation and local circulation. Clinical trials indicate that soft-laser treatment can contribute to faster wound healing (Neto et al., 2019). With the device’s diffused optics, the wound surface can be treated evenly with minimal thermal load. Is your dog limping or having joint pain? Sound familiar? Older dogs and cats can suffer from joint wear and injuries. They don’t have to suffer unnecessarily. Veterinarians also use the Energy-Laser L2000 Pro as an adjunct treatment for musculoskeletal complaints in small animals. The pain-free, non-invasive treatment is well tolerated by animals. Ask your veterinarian’s opinion before starting treatment! How to use it? It’s this simple: 1 Charge the battery Connect the MEGA Li‑Ion battery to the supplied charger. Full charge takes about 4 hours – afterwards it provides roughly 1 hour of treatment. 2 Connect the app Download the free Energy Laser app to your Android phone. Turn on Bluetooth and pair with the device. Set the treatment time (10 sec – 10 min) and the power level. Attention! The device works perfectly well without the phone app; in that case calculate treatment times assuming 5 Joules delivered every 10 seconds. 3 Put on protective goggles Eye protection is mandatory for Class 3B lasers! Put on the supplied protective goggles – if you treat someone else, they should also wear eye protection whenever the beam is near the head. 4 Treat the painful area Place the laser emitter on the skin area to be treated. The red LED indicator shows the treatment area. Move the head slowly over the treated zone. The device automatically switches off after 5 minutes. How does the soft-laser work? The scientific name for soft-laser treatment is photobiomodulation (PBM), previously known as LLLT (Low Level Laser Therapy). The first studies were performed by Hungarian physician-researcher Endre Mester in the 1960s, and since then thousands of scientific papers have investigated the method. The 808 nm infrared laser beam penetrates the skin to reach deeper tissues. The light acts on the cytochrome c oxidase enzyme in the mitochondria of cells – the cell’s "power plant". As a result, ATP (adenosine triphosphate) production increases, which is the cell’s energy currency. Increased energy production can support the cells’ natural regenerative processes. According to the scientific literature, photobiomodulation can act on three main levels: it may help improve local microcirculation, reduce inflammatory processes, and contribute to accelerated tissue regeneration.

You’ll see how simple and quick laser therapy at home can be. What’s included in the package? 1 pc Energy-Laser L2000 Pro laser head unit with built-in optics 1 pc MEGA Li‑Ion battery (3.7V / 1950 mAh) 1 pc Li‑Ion battery charger 1 pc USB cable 1 pc USB power adapter 1 pc protective goggles 1 pc user manual 1 pc LLLT treatment guide booklet Aluminium carrying case Protective goggles – mandatory accessory Protective goggles are mandatorily included for Class 3B lasers. The 808 nm infrared radiation is invisible – you cannot tell with the naked eye if it reaches your eyes! It is recommended that the patient also wear goggles when the treatment area is near the head (a second pair can be purchased separately). Maintenance Cleaning is simple: wipe the laser head with isopropyl alcohol, then dry with a lint‑free cloth. Never expose the battery to temperatures below -5°C, high heat, water or shocks! Frequently asked questions Is wearing protective goggles mandatory? Yes! The Energy-Laser L2000 Pro belongs to laser class 3B. Direct exposure of the beam to the eye can cause damage. The patient should always wear protective goggles during treatment – these are included in the package. Never point the beam at the eyes! Can I use it if I have cancer? Do not treat cancerous tissue without medical supervision and written permission! Direct laser treatment of tumours is contraindicated. In palliative care or terminal phases, it may be used as an adjunct for pain relief under specialist control. Always consult your treating physician! Will I feel anything during treatment? Soft-laser treatment is painless and non-invasive. The 808 nm infrared light is not visible to the naked eye, but the built-in red LED indicator shows the treatment area. Some users may feel a slight warmth at the treated spot, which is a normal reaction. How often should I use the device? Generally 1–2 treatments daily are recommended, each lasting 1–10 minutes depending on the area size and problem. The device automatically stops after 5 minutes to warn against overuse. If a longer session is needed, you can restart after switching off and on. For acute complaints, daily treatment in the first 1–2 weeks, then 2–3 times weekly as maintenance may be sufficient. Detailed protocols are available in the Energy Laser app. How does the L2000 Pro differ from the smaller Energy Laser models? The L2000 Pro is the flagship of the product family, with four 500 mW diodes and 2000 mW total output. That is 4× the power of the L500 Pro (500 mW) and 2.5× that of the L800 Pro (800 mW). It delivers 20 Joules in 10 seconds compared to the L500 Pro’s 5 Joules. It is recommended for larger joints (knee, hip, shoulder) and deeper tissue problems. Is the device suitable for home use or only for clinics? Although the L2000 Pro is primarily designed for professional use (sports physicians, physiotherapists, dermatologists), it can be used at home if you follow the user manual and safety rules. The Bluetooth app makes it easy to set treatment time and power. How long does one charge last and how long does the battery last? The MEGA Li‑Ion battery (3.7V / 1950 mAh) provides roughly 1 hour of treatment on a full charge. Charging time is approximately 4 hours. A USB charger and power adapter are included. What is the difference between soft-lasers and cheap LED lamps? The Energy-Laser L2000 Pro contains a real diode laser that emits coherent, single-wavelength light – fundamentally different from the scattered light of LED lamps. Lasers deliver much more targeted energy into deep tissues. Cheap LED “laser” devices are not true lasers and cannot deliver energy to similar depths. Pay attention to CE medical certification and actual laser power!

Energy-Laser L500 Pro – If you need a compact, focused-beam device for smaller joints (fingers, wrist, elbow). The 500 mW output and spot beam are ideal for small-area precise treatments. Energy-Laser L2000 Pro ⭐ – If you need to treat larger joints (knee, shoulder, hip) or deep tissues. The 2000 mW total output and 11 cm² beam area shorten treatment time while the high power density ensures deep tissue effect. Safe Laser 1800 Infra – This product is the main market competitor to the L2000. Similar-sized areas can be treated at once with both devices, but Safe Laser emits a much lower power density. Because the prism scatters the laser light, it can be used without protective goggles (Class 1). Safe Laser treatments are slower due to the low energy delivery – about 6× longer than with the L2000. Treating a single knee typically takes 15–20 minutes longer with the SF 1800 than with the Energy-Laser L2000. Despite its lower power, the Safe Laser 1800 is offered at a price close to the two-category-more powerful Energy-Laser L2000.
