Biolight 3000 Repair

By on April 23, 2020









This Biolight was brought into me after another repairer had tried to patch it up and although having charged a large sum, had not satisfied the customer with a positive repair.

First of all, what is the purpose of this light? Infrared (600 – 950nm) as well as near Infrared (750 – 2500nm) light has been proven to provide a number of health benefits, including relief from muscular pain and arthritis.

Unlike a heat lamp, which creates heat, the LED Biolight provides certain wavelengths of light without creating possible harmful heat.

This customer uses this particular unit both on the horses that she cares for as well as herself. She has several of these units, which were quite expensive. The previous repairer found that the battery pack had leaked, so after replacing the pack, fitted an external switch. Unfortunately, every time this was placed on charge, the lights would come on and the batteries would never reach full charge and would go flat very quickly.

After disassembly, I could see many tracks had been damaged. After testing the battery pack, I was surprised to find that it was dead flat. Disassembling the pack didn’t give me any confidence in its operation. It was clear that it had been made poorly by the repairer.

After approval from the customer, a new battery pack was purchased. But the problem remained of the light staying on during charging. In fact, the repairer had fitted an on/off switch as the original momentary switch would no longer work with the damaged circuit.

After careful inspection of the circuit board, I realized that it could not be practically repaired within a reasonable budget. I felt that that bypassing the charging system would allow the light to operate correctly independent of the charging circuit on the board.

This enabled the battery to be directly charged without the light staying on during charging.

After discussions with the customer about the most viable option for repair, it was decided simply to purchase a universal charger with the appropriate barrel jack. This ‘intelligent charge’ system would be able to charge the battery and take the place of the charging circuit on the board.

After charging the battery and testing the operation of the unit, both the infrared and near infrared lights worked.

I was able to pass the unit onto a now satisfied customer. Sorry guys, no video this time!

    Good job Mark on fixing and replacing the charger and the old bad batterypack. I however wonder if such devices do anything positive that is scientifically proven. Like the well known and very expensive Biostabil bracelet that just contains magnets out of old loudspeakers.

      Hey Albert,
      I have no scientific proof and am not trying to promote the product, but I did use it while I was testing it on my back and muscles, which I am in constant pain with & it did seem to work. Placebo effect? I don't know.
      Many of these are used by practitioners, chiropractors & registered massage therapists.
      Whatever the case, it was good to get this unit up and running 🙂

        Understood Mark. I have visited my chiropractor many times just recently for my back and several years ago for my back and my neck. Hoping to get rid of my heavy migraines. Those I did get quite often in the past every 2 months or so since my about 8th year. My lower backpains still frequently pop up (I am just too tall for most jobs I did. Almost 2 meter.) but thank God my heavy migraines are very seldom now. I also started a healthy job recently as delivery mailman man on bicycle. Not that I had any real say in the matter but I like it thusfar. (Spring and coming Summer are helping much!). But I do not think I ever have seen my chiropractor using such a Biolight.

    Good, Mark. We need to be practical. And you did this way, adding an external power supply and resolving the problems in a quick, cost-effective and efficient way. Greetings.

      Hey Henrique,
      Sometimes it's hard to balance between what the customer can afford, the worth of the item and a complete repair. This seemed the best option after discussions with the customer.
