The 10 Best Black Lights for Finding Cat Urine Stains
1. Vansky UV Flashlight Black Light — Best Overall
| Wave Length: | 395 nm |
| Material: | Aluminum |
| Power: | AA batteries |
The Vansky UV Flashlight Black Light is the best overall backlight for finding cat urine stains. Its ergonomic design makes it comfortable to hold and easy to use. It’s also lightweight and water resistant. The large light uses 51 ultraviolet LEDs to illuminate a large area, making it easier to see the cat’s urine without the light pointing directly at it.
The biggest downside to the Vansky is that though the light covers a large area, it’s not that bright, so your room must be quite dark when you are using it to see the urine. Many customers also wish that it used rechargeable batteries instead of alkaline ones that don’t last long and need frequent replacement.
- Large light
- Water resistant
- Ergonomic handle
- Lightweight
- Not that bright
- Alkaline batteries
2. Morpilot Blacklight Flashlights UV Flashlight — Best Value
| Wave Length: | 395 nm |
| Material: | Aluminum |
| Power: | AAA batteries |
The Morpilot Blacklight Flashlights UV Flashlight is the best blacklight for finding cat urine stains for the money. It is a set of two lights for the price of one, and each has a durable aluminum body that is impact-proof and waterproof. The textured grip makes them comfortable to carry and less likely to slip as you use them. Although these flashlights are small enough to fit in your pocket, 12 LEDs produce a high-intensity light that makes it easy to spot cat urine.
The only real downside about the Morpilot is that many users complain about the design of the power switch, which can result in the lights turning on and off intermittently as you use them. A few people also complained that you must angle the light just right to see the cat’s urine.
- Impact-proof and waterproof
- High intensity
- Textured grip
- Small size
- Poor switch design
3. NEXTORCH Pocket-Size LED Torch for Pets Urine and Stains — Premium Choice

The light is powerful and can spot urine from several feet away. Many users also report that the batteries last quite a while.
The downside to the NEXTORCH is that while the light is quite bright, the beam is narrow, so it can take a while to search a large area.

- Powerful light
- Narrow light beam
4. Yunyeeneen UV Blacklight Flashlight
| Wave Length: | 385–395 nm |

Many customers report that they can see every speck of dust while using it, and the ergonomic handle is easy to grip and use despite the large light. Another great feature of this flashlight is that it’s waterproof, so you can use it in any weather.
The downside to the Yunyeeneen is that the rechargeable batteries lose charge quickly, causing the light to dim and making it hard to spot cat urine. Many users also complain that replacing the six batteries can get expensive. The number of batteries also contributes to the weight of the light, which is considerably heavier than many other models.

The rechargeable battery holds its charge for many hours, and most customers find it easy to use.
The downside to the DARKBEAM is that it uses a micro-USB charging system that some customers feel is dated. It can also be hard to find a replacement cable if something happens to the included one. Many users also complain that charging can take a long time if you let the power get too low.

Buyer’s Guide – Choosing the Right Black Light for Finding Cat Urine
When operating a UV blacklight, it’s important not to shine into your eyes or your pet’s eyes. Prolonged exposure could affect your vision over time, so it’s a good precaution to only use these lights when needed.
While you’re looking for a blacklight to find cat urine, here are a few things to consider.
Wavelength
UV lights differ in wavelength, usually 10nm to 400nm. Nm stands for nanometer, which is one-billionth of a meter. The recommended wavelength of the blacklight needs to be between 365nm and 385nm because it’s the best for finding cat urine. We do not recommend lights with 395nm or 400nm because they are too close to visible light, which will not detect cat urine. Most blacklights will tell what wavelength they are.
Size
Blacklights come in different sizes, with some being very small and compact. As long as the wavelength is in the recommended range, the size shouldn’t matter.
Protection Glasses
Some blacklights come with protection glasses. These help in spotting the stains, as well as protecting your eyes. If you find a light that doesn’t come with glasses, you can purchase them separately.
Number of LED Lights
The number of lights makes a difference in finding cat urine. The blacklight should have at least 9 to 12 bulbs, but some have 50 to 100 bulbs. The more bulbs, the better.
How To Use Blacklights Effectively
When checking for cat urine, the room will need to be as dark as possible for effectiveness. Nighttime is the best, and make sure no visible light is shining in, such as a streetlight or porch light. Close your blinds or curtains too.
Conclusion
