“Resonant Light Technology Inc is a Canadian Corporation that has its roots well grounded in the R&D of integrated light and sound technology for the purpose of controlling microorganisms.

Resonant Light Technology Inc produces state of the art energy equipment for the health and wellness, animal care and agricultural industries. All of our devices are engineered for ease of use, which has resulted in as many home users as professionals.

A Canadian design and manufacturing company since 1996, we build everything to medical standards and utilize integrated light and sound frequencies, as well as electrical and radio frequencies to achieve powerful results. The frequencies and their applications are often referred to as PEMF Technology or Rife machines and thousands of people, including international health care professionals, report positive results with its use.

The company employs a full-time R&D department, a multilingual sales staff and a complete support team, all dedicated to providing optimal customer service.

What is Photon Emission Resonant Light Technology?

This is the use of resonant light emission for the control of viruses, bacteria, fungi, yeasts, and insects. Our research involves the development of equipment and the evaluation of the effectiveness of its use, the latter of which we share with the public.

What Distinguishes Resonant Light Technology Inc?


Our flagship product is the PERL M+, a powerful device that emits specific light and sound frequencies to organisms as far as 30 feet (10 meters) away.

The PERL comes with a ProGen II 4050, which is a programmable frequency generator with our most popular frequency banks pre-programmed. The ProGen II can be purchased separately from the PERL or packaged with a number of contact devices and attachments. In that way, it can be used as a professional-quality TENS device.

As we are extremely committed to customer service, we not only provide an instructional DVD and comprehensive manual with your PERL purchase; we call you after your PERL device arrives at your home. This is our way to ensure your setup and initial use is a breeze, setting you up for years of successes.
