For which complaints can it be used as an adjunct treatment? Knee, shoulder and hip-related complaints Treating large joints usually does not involve a single point. For knee osteoarthritis, for example, multiple sides of the joint and surrounding soft tissues may need treatment. The L2000 Pro’s four laser diodes cover a large area, so the treatment can be performed with fewer repositionings. This is one of the device’s key practical advantages. It is especially beneficial for therapists because treatment time is significantly shorter than with point lasers. Detailed guide for knee pain treatment → Lower back, back and paraspinal soft-tissue complaints Low back pain may have many causes: muscle and joint overload, disc-related problems, nerve involvement or other conditions. For persistent or radiating pain, diagnosis is required first. With appropriate evaluation, soft laser can be used as an adjunct for the paraspinal muscles, ligaments and painful soft-tissue areas. The larger optical treatment area speeds up multi-zone treatments. Lower back and spine pain treatment guide → Extensive tendon, muscle and attachment complaints Treating a long tendon segment, a large muscle group or multiple nearby painful points with a point laser can be time-consuming. The L2000 Pro’s larger treatment area is advantageous in such cases. Soft laser is an adjunct in tendon and muscle rehabilitation. Offloading, gradual reloading, strengthening and physiotherapy remain the foundations of treatment when needed. Soft-laser for tendonitis → Sports injuries and rehabilitation For muscle strains, tendon or ligament complaints, photobiomodulation can be part of rehabilitation. The wireless design and short treatment time are practical in sports settings. In acute injuries, rule out fracture, complete rupture and other urgent conditions first. Treatment should not be an excuse to return to full load too early. Soft-laser treatment for sports injuries → Musculoskeletal complaints in small animals The L2000 Pro’s larger treatment area can also be practical on joints and soft-tissue areas of dogs and other small animals. The treatment is painless and well tolerated by many animals. An animal’s eyes must also be protected, and treatment should be performed based on a veterinary diagnosis. For tumors, lameness of unknown origin or deteriorating condition, home attempts do not replace a veterinarian. Soft-laser therapy in small animals → Scars and ulcers Photobiomodulation has been studied as an adjunct for tissue regeneration and scar treatment. The larger treatment area can speed treatment of surgical scars. Infected, exuding, deep or hard-to-heal wounds should be treated under the supervision of a wound-care specialist or physician – the device should not directly touch the wound. Diabetic foot ulcers and leg ulcers are not to be treated casually at home. Why choose the Energy-Laser L2000 Pro? 2000 mW total output The four 500 mW laser diodes together deliver 20 Joules total energy in 10 seconds. This enables short treatment times even on larger body areas. Larger area with a single treatment position The multi-diode, diffused optics cover roughly 11.3 cm². You need to reposition the head less often than with a small-spot point laser. Particularly practical for large joints Treating the knee, shoulder and hip area can involve many points. The L2000 Pro’s larger treatment area delivers real time savings for these indications. Compact, battery-powered design The head unit weighs approximately 200 grams. There is no mains cable during treatment, making it comfortable to use at home, in the clinic or in sports settings. Bluetooth control with Android app The app helps adjust treatment time and power settings. This function is generally unnecessary for lay users – the device is designed for phone-free use. However, it can be useful for therapists. Safety protection and accessory goggles Auto shut-off, electronic overheat protection and a visible aiming light assist safe use. Appropriate laser-protective goggles are included in the package. Is the Energy-Laser L2000 Pro right for you? Good choice if you plan to regularly treat the knee, shoulder, hip region, back or other larger body areas. Particularly practical if a small point laser would require too many adjacent treatment positions. The L2000 Pro delivers energy to a larger surface at once. Also advantageous for multiple users, e.g., family use, athlete treatments, veterinary practice or therapists where short treatment time matters. Not the right choice if you primarily need to treat very small joints, a single tendon point, a finger or other very small area precisely. For those, a small-spot point laser may be more convenient. Advanced device: high output means rapid energy delivery, so treatment time and power must be set consciously. You don’t need a physics degree, but the “one more minute” approach is not a good idea here. See the Energy-Laser family in use Introduction to the Energy-Laser system The video shows basic device handling and the most important safety rules. The L2000 Pro’s multi-diode head differs from point lasers, so always follow the L2000 Pro user manual for specific settings. What does photobiomodulation mean? During soft laser treatment, tissues are exposed to light of a specific wavelength and dose. This process is called photobiomodulation, abbreviated PBM. Light interacts with cellular light-absorbing molecules and can influence several biological processes. Research investigates its effects on cellular energy metabolism, local inflammatory signaling and regenerative processes. The L2000 Pro uses four diodes of 500 mW each. The 20 Joule/10 seconds specification refers to the device’s total optical energy output, distributed over the larger treatment area. This is not equivalent to 20 J/cm² energy density. The main advantage of the high total output is short treatment time. It does not mean you should always choose maximum power or longer sessions for every problem. Photobiomodulation is dose-dependent: more is not automatically better. How to use it in four steps 1 Charge and check the device Fully charging the MEGA Li-Ion battery takes about 4 hours and provides approximately 1 hour of continuous operation. Before use, check the head unit and battery charge level. 2 Set up the treatment In the Android Energy Laser app you can set treatment time and power. According to the source material, the device can also be used without the app; follow the manual for correct manual-mode operation. 3 Put on appropriate protective goggles The L2000 Pro is a class 3B laser device. Both the operator and the treated person must protect their eyes. Direct or reflected laser exposure to the eye is hazardous. 4 Place the head on the target area Place it steadily on clean, intact skin and follow the treatment plan for the specific complaint. The red aiming light helps identify the treatment area; it is not the therapeutic 808 nm laser beam. Frequently asked questions What does 2000 mW output mean? The device contains four 500 mW laser diodes, giving a total output of 2000 mW. Together they deliver 2 Joules per second, and 20 Joules in 10 seconds. Is the 20 Joules delivered to every square centimetre of the treatment area? No. The 20 Joules is the total energy output of the four diodes over 10 seconds, which is distributed across the area covered by the head. When calculating energy density, consider the actual irradiated area. How is the L2000 Pro different from a point laser? A point laser concentrates energy on a small spot, which is practical for tiny joints, tendon points and precise targeting. The L2000 Pro uses multiple diodes to cover a larger area, making it faster for knees, shoulders, back and extended soft-tissue regions. Is wearing protective goggles mandatory? Yes. The Energy-Laser L2000 Pro is a class 3B laser device. Appropriate eye protection is required for both the operator and the treated person. Never point the laser at the eyes or reflective surfaces. Do I need a mobile phone? The Android app conveniently assists with power and treatment time adjustments. According to the source, the device can operate without the app, but manual-mode options and defaults must be followed as described in the supplied manual. Does higher power automatically mean better results? No. Wavelength, treatment area, dose, time, frequency and correct diagnosis all matter for the desired outcome. High output’s advantage is fast energy delivery, not unlimited dose escalation. How long does a treatment last? Total time depends on the size of the treated area, chosen power and prescribed energy dose. Because of the 2000 mW total output, a larger area can generally be treated in a short time, but always follow the specific protocol. For home use or for professionals? It can be used in both settings, but due to its high output and adjustable parameters it requires more conscious treatment planning than a simple fixed-setting device. It is suitable for home users who are willing to follow the manual and safety rules. What does the package include? The device is shipped with accessories required for use, charging, transport and safe handling. 1 pc Energy-Laser L2000 Pro laser head unit with built-in optics 1 pc MEGA Li-Ion battery, 3.7 V / 1950 mAh 1 pc Li-Ion battery charger 1 pc USB cable 1 pc USB power adapter 1 pc laser-protective goggles 1 pc user manual 1 pc LLLT treatment guide booklet 1 pc aluminium carrying case Do you need a second pair of protective goggles?
