How to Check UV Lamp Is Working

There are many benefits to using UV lamps, but only if they are working correctly. If your lamp is not performing as it should be, there isn’t much point in continuing to use it. On the other hand, taking the time to check out your UV lamp can save you money and make sure that you get the best results possible from every treatment.

How to Check Uv Lamp Is Working

The UV lamp is a critical element of the tanning process. Therefore, it is essential to test it at least once per day to ensure that the bulb has not burned out and that you are getting an even tan without any areas being under or over-exposed. This article will show you how to check uv lamp is working to be sure it’s working properly for each use.

10 Ways on How to Check UV Lamp Is Working:

1. Check Voltage with batteries: 

To check if UV lights are working, put batteries in the flashlight and turn it on. The visible indicator will be visible on the surface of the liquid. If there is no bright or bright spot visible on liquid, then UV light is not working. In that case, you should replace new UV lamps. Check this link to buy new UV lamps: how to change UV LEDs

2. Turn off lights and cover water surface:

If the light is passing through the clear plastic, then UV Tube is working correctly. If you put a piece of black color paper on the water’s surface and if you see some light on the paper, then the tube is working.

3. Check Power supply:

Connect the Uv tube to the power supply. Turn on the UV lamp. If you see some white dust surrounding the coil, then UV Tube is working correctly. If there is no white dust surrounding the coil, then check the Power supply or replace the new power supply.

4. Check Dry Eye Testing Systems:

Dry eye testing systems can be used to check the UV lamp. There are two reasons for this. First, UV lights emit electromagnetic waves with a frequency of about 10 Hz to 400 nm, similar to visible light waves.

When people see ultraviolet rays or ultraviolet radiation, they look like visible light. Second, there is no visible light in the visible light range. If the ultraviolet lamp is not working, there will be no visible light emitting from it.

5. Check Ultraviolet Pen Light:

Even if you have an ultraviolet penlight, you can use it to check whether your UV tube is working or not. This is because the principle of using a flashlight to detect an electronic ultraviolet lamp ultraviolet lamps and ultraviolet lights will not cause damage to the human body.

6. Check UV absorption bottle:

Fill water, white vinegar or alcohol in the transparent glass bottle. Make sure the concentration of the solution is more than 25% (note that some distilled water is not enough). Please turn on the UV lamp and put it on one side. If there are no fluorescent materials in it, O-Zone will form, and the solution will become darker. If there is no O-Zone or fluorescent material in it, the lamp is not working.

7. Power up Electronics:

Power up the UV lamp unit. If you have a voltmeter, use it to check if the power supply is working or not. The Voltage should be more than 24 volts. If there is no voltage, you should replace the new power supply.

8. Check for Pressure:

Put the ultraviolet lamp in the aquarium, fishbowl, or glass vase. Make sure that there is no object between the light and water. If you see a blue dot on the water’s surface, then the UV tube is working correctly.

9. Check for Dust:

UV lamps with high-pressure mercury vapor have a very high voltage. The electric discharge that occurs when the lamp is lit will cause dust to stick to its surface, which may affect the brightness of the ultraviolet light in some cases. Therefore, check these lamps every day before use to make sure they are clean and bright.

10. Power up UV bulb:

Power up the ultraviolet lamp with the power supply. If you have an ammeter, then check if there is any current in it or not. A good lamp will have a low current when it lights up. If you do not see any light on the water’s surface, replace the new UV lamps.

Things to Consider When Checking UV Lamp:

Lamps that are used in fish tanks need to be checked periodically. Lamps can go out quickly if they’re not working properly, and the lamp should only be replaced when its full potential cannot be realized. But before you make a purchase decision, here are a few things you should consider.

1. Durability:

The lamp isn’t going to last forever, and you must get what you pay for. However, the more expensive lamps typically have a longer lifespan, saving you money in the long run. Some lamps come with warranties, so if they burn out, you can get a replacement.

2. UVB and UVA:

Ultraviolet B (UVB) light and ultraviolet A (UVA) light are coming from the lamp. Both types of light play an essential role in the tank, but it’s necessary to ensure enough UVA since sunlight doesn’t produce this type.

3. Size:

UV lamps come in different sizes, and you’ll want to make sure the size of your lamp matches the size of your tank so you can get optimal coverage. For instance, if you have a 55-gallon tank, then a 15-gallon lamp will not be sufficient for your needs.


In these blog posts, we have covered how to check UV lamp is working. You can take a quick look at the sticker on the lamp to find out if it needs replacing. If you’ve been neglecting your UV light, the chances are that it is not working as well as it should be and may need replacement soon.

The best way to know for sure is by checking the sticker on the unit. This will tell you when it’s time for a new one, usually every ten months or so, depending on how often you use your UV light. But, of course, it’s always better to replace before things get too bad!
