My curing light is not working or does not turn on
If your curing light is not working or does not turn on, the most useful thing to do is to start with a few simple checks.
In most cases, the issue may come from charging, the charger being used, the battery, or proper contact inside the lamp.

1. First, check the charging
The lamp must be charged correctly.
For the battery to be charged to 100%, it must remain charging until the light on the base changes from orange to green.
If the lamp has not been charged until that change of light, it may simply not be fully charged yet.
On the other hand, leaving the battery charging longer than necessary can cause overheating and damage the battery.
2. Check the charger being used
Using an unsuitable charger can damage the battery.
If your lamp is no longer working properly, make sure you are using a charger that is compatible with this model.
A charger that is not designed for the lamp battery can cause charging issues or damage the battery over time.
3. Consider storage and usage temperature
Batteries can be sensitive to very high or very low temperatures.
If the lamp has been exposed to strong heat or a very cold environment, this may affect how it works.
If you are unsure, let the lamp return to a normal temperature before testing it again.
4. Avoid repeated full discharges
Letting the battery fully discharge repeatedly can reduce its lifespan.
If the lamp is often left completely empty for a long time, this may eventually affect its performance.
The simplest approach is therefore to avoid frequent full discharges whenever possible.
5. Check storage conditions
A battery can also deteriorate if the lamp is stored for a long time without being used or occasionally recharged.
If your lamp has not been used for a long period, this may explain why it is difficult to restart.
In that case, let it charge correctly and then test it again.
6. Check that the battery is properly installed
This is an important point.
Make sure the battery is correctly installed inside the lamp.
To check this, gently turn the lamp upside down:
- you should not feel the battery moving inside.
If you do feel the battery moving:
- remove the silver ring if necessary;
- then tighten the lamp as much as possible so that the battery is in perfect contact inside.
This ring is used to protect the lamps while they are stored in the warehouse. In some cases, it can therefore prevent proper contact if it has not been removed.
7. In what order should you do these checks?
If you want the simplest method, follow this order:
- let the lamp charge properly until the indicator turns green;
- check that you are using the correct charger;
- check that the lamp has not been exposed to extreme temperatures;
- make sure the battery has not been subjected to too many full discharges;
- finally, check that the battery is correctly positioned and does not move inside the lamp.
8. What should you do if the lamp still does not work?
If, after these checks, your lamp still does not work properly, you can contact our customer service team with as much detail as possible about the issue you are experiencing.
It is helpful to indicate, for example:
- whether the lamp no longer turns on at all;
- whether the charging light works or not;
- whether the battery moves inside;
- whether you have already tested a full recharge;
- and, if possible, when the issue first appeared.
This helps us review the situation more quickly.
Key takeaways
If your curing light does not turn on or does not work properly, start by checking:
- the battery has been fully charged;
- the charger being used;
- exposure to extreme temperatures;
- repeated full discharges;
- storage conditions;
- and the correct position of the battery inside the lamp.
In many cases, the issue may come from one of these points.
If the issue continues after these checks, contact our customer service team with as much information as possible about the problem.
