Let me just say this first, this is an awesome 2 pack flashlight 2 in 1 set. The regular light is very powerful and bright. This is also the best flashlight set I have ever owned it’s that nice! Now if you bought this for finding pet stains you are in luck. For pet stains you need a very high power and proper black light. This is almost powerful enough but like almost all black light flashlights it falls a little short. You can find reflective creatures such as scorpions with ease. And certain types of stains on slick surfaces. But the main reason I purchased this was for UV resin. This is an amazing product for just that. It cures it fast and with ease.
If you are just looking for a regular flashlight then this is for you. You can adjust the size with a push or pull of the product and it has 4 settings; bright white light (it really is white not yellow like others), a dim light, flashing light, and a nice UV light! Overall great buy and I highly recommend.
