Frequently Asked Questions
What is the difference between 365nm and 395nm?
365nm light provides purer UV output with minimal visible glare. 395nm is more common and cheaper but includes visible violet light. For accurate detection, 365nm is generally preferred.
Can UV flashlights detect pet urine?
Yes, pet urine contains compounds that fluoresce under UV light. 395nm models are sufficient for most household stains. It is effective for finding hidden messes in carpets.
How long do the batteries last?
Runtime depends on the model and usage. Rechargeable units often offer 2 to 4 hours. Battery models depend on cell quality. Check product details for exact runtime.
Are these lights waterproof?
Many models feature waterproof ratings like IPX4 or IP65. They can withstand rain and splashes but may not survive full submersion. Check specifications before using in wet conditions.
Do UV lights fade over time?
LEDs have long lifespans but intensity may decrease with use. Proper care extends their life. Avoid dropping or exposing to extreme heat to maintain brightness.
What can UV flashlights detect besides urine?
They can identify scorpions, stains, counterfeit documents, and certain minerals. UV resin curing is another common application. They are versatile for inspection and hobby use.
How do I know if a battery is low?
Modern models have LED indicators or displays. Low power warnings appear as red lights or percentage drops. Check these indicators before starting a long inspection.
Can I use a UV flashlight on skin?
Avoid direct exposure to eyes or skin. UV light can cause irritation. Use it for detecting items or objects rather than direct human exposure.
