Things To Consider When Buying UV Light For Urine Detection

Look for these features while buying a UV light for urine detection:

  • Durability: Consider buying products made of durable materials with protective functions such as waterproof and dustproof coatings, making it suitable for outdoor adventures. The aluminum alloy is sturdy and can provide a solid structure for the flashlight. With such durable finishes, you can use your UV flashlight even during your outdoor adventures.
  • Nanometers: The wavelength range of 365 to 385nm can effectively detect urine stains. The higher wavelength blends into the standard light, so they may not achieve the purpose.
  • LED count: This factor will determine the intensity of the UV black light. Most detectors have at least 50 LEDs. It is best to use a black light with 100 LEDs because it has a larger coverage area.
  • Protection: Direct viewing of ultraviolet rays is harmful to the eyes. Therefore, choose a light that comes with protective sunglasses.
  • Versatility: Most UV flashlights are multipurpose. You can use these UV flashlights when repairing AC gas leaks, identifying fake documents or using them in medical forensics. They also make excellent camping gear.
  • Portability: Most flashlights are portable, compact, and lightweight. Therefore, a portable flashlight is ideal for indoors and outdoors.

Frequently Asked Questions

1. How does urine glow under the light?

Urine is composed of urea, creatinine, and phosphorus. Phosphorus reacts with oxygen in the air and illuminates under ultraviolet light. It is difficult to remove this compound with only one wipe. Therefore, you can identify compounds left in the urine using a black light, not the urine itself.

2. Is it only urine that glows under the light?

You can detect various organic substances and biological fluids that glow in the dark. Saliva, urine, semen, and some minerals glow when exposed to ultraviolet light, which is the reason that UV flashlights are also used in medical forensics.

3. Can I detect cat pee with a UV light?

Yes, UV light can detect urine, regardless of the animal. However, the glow may be weak if the urine is not completely dry. Cat pee, in particular, glows brightly during hygiene inspections with UV light, as it has a high phosphorus content.

4. Is a UV light the same as a black light?

UV light is composed of UVA, UVB, and UVC lights. Blacklight falls under UVA light and emits ultraviolet radiation of low energy and a long wavelength in the UVA band. Another name for blacklight is Wood’s lamp.

5. What does dog urine look like under UV light?

Under UV light, dog urine usually glows with a pale yellow or greenish color.
