Cordless LED problems

Cordless LED problems

Recently we are seeing significant inquiries about problematic Cordless LEDs aka “Wireless LEDs”. The primary complaints is intermittent or totally non-functioning  devices. The vast majority of criticism involves “newer” units no longer covered under the manufacturers warranty.


Excessive wear is obvious, presumably a result of constant removal & replacement of batteries for charging. Many units have missing contact surfaces, or the plastic clip that retain the battery is mangled or worn.  Still others the battery itself is already dead.

Loupes with “built in” LEDs have the added issue of wires or flexible PCBs in the arms not functioning properly as a result of folding the frame arms.

Run Times:

Common run time of traditional battery pack is about 8-10 hours, some longer. On the other hand, Cordless LEDs requiring charging every couple hours seems common.

Consider this:

If you work 4-5 days a week and your cordless unit needs charging every 2 hours or so, – in a single year you could be removing & replacing the battery hundreds to well over a (1000) thousand times. Ask yourself: how many times can a lithium Ion battery be charged? – How long will my charger last running nearly constantly to keep up with my battery needs.

Before cordless LEDs, it was extremely rare to see a newer traditional Battery Pack in need of repair. (Except for accidental damage). Now, we see some pristine cordless LEDs no longer functioning properly after only about a year of normal use.


 Run Time,

When looking for a cordless LED, be sure to look for the run time on a single battery. Some claim run times up to 4-6 hours, but in the fine print you may find thats on the lowest setting & using multiple batteries.


Also inquire about the weight of the entire device that will be added on the bridge of your nose. Total weight, not just the LED  without the battery. Read the fine print

Other criticism,

Impressions on a users nose caused by cordless units additional weight. Some complain of cordless LEDs shadow while using the dental offices overhead light. Still others report headaches & pain on bridge of their nose. A few, who questioned the seller of the device, said they were encouraged to limit or use the unit less frequently.

Considering repairing your loupes or LED? Are you being told by the company that sold the device to you in the first place, the simple repair you need is going to take weeks & cost a small fortune?

Reading independent reviews about the company that sold you the product in the first place is a great idea. Alternatively, speaking with colleagues facing similar issues can be a source of guidance. Investigate a companies reputation for Service & Support after the sale?

Common Cable Failure Causes: 

  1. Hardening, cracking, brittle cables, as a result of age or improper cleaning.

  3. Heat, usually generated by continued use of a thinning or failing cable.
  4. Non professional or mediocre repair, such as taping a problem area

Proper Cable Care:

  1.  Using alcohol or similar solvents to clean a cable contributes to cracking in addition to deterioration. While It may clean the cable, it also dries it out, making it stiff and prone to cracking, On the other hand cleaning  with mild hand soap and water can make them last a lot longer.
  2.   Winding or twisting a cable tightly or knotting it is very harmful. Repeated tight coiling as opposed to loose rolling will diminished cable life.

Premium Cable Features:

  1. Conductors sized for proper operation is crucial, while at the same time offering improved reliability. Oxygen free copper, silver plated copper, as well as other premium conductors are the best choice
  2. Flexible jacket materials. Most newer cable coverings are made with advanced polymers, silicone or other quality materials proven to remain supple longer.
  3. Long wearing cables, for example: nylon reinforced or advanced  material type. proven to remain flexible longer, unlike low quality counterparts.

Repair of Common LED Problems

Connector Assembly

We find Repairs for common LED issues are usually  due to a break or short in wiring wire between the LED and the battery pack. Adding a strain relief to prevent a recurrence of the same problem is an easy yet affordable improvement.

Frequent Causes

Most issues are not the fault of manufacturing defects, but rather an accident other unplanned event. If a unit falls on to a hard surface it can damage internal components, in spite of looking perfectly fine. 

“Hooking” the cord on something or stretching it usually results in damage. LED cables are easy to snag.

Most times this potential problem can be minimized by keeping the cord underneath your lab coat. Using a twist tie to coil up  excess slack is another good idea. Repairs of common LED issues can be avoided by proactively shortening the cable to suit your needs.

Repair costs

The majority of LED Light Repair for Common Problems are easily fixed,  therefore very affordable, yet some are under the impression that repair of the unit is either not possible or expensive. The fact is while advances in technology are increasing, so are manufacturer’s desire to lower costs.  One of the easiest ways to lower cost is to use cheap plastic components. Some of the most reliable LEDs have metal components which are far superior to low cost plastic. In most cases a repaired quality unit can outlast many current bargain models.
