Question 1

The product description doesn't even mention the light detecting and showing dog urine in carpet......Does it?

Accepted Answer

I don't know why some of the others are saying it doesn't show dog urine stains on carpet. It does.  Keep in mind that if you are simply looking in a house that has light coming in from windows - even if your lights in the house are off, it won't be dark enough.  Unless you can block all light, wait until nighttime, close your blinds / curtains to block street lights and such, turn off all lights in the area to get it as dark as possible and turn it on.   There were obvious dog pee stains in areas that I wasn't aware of before, urine stains in the bathroom that I thought was clean.

Question 2

Is this light good for use in hotel rooms for detecting "nasty" stains ??

Accepted Answer

On "The Doctor's" TV show, the GYN/OB doctor was emphatic that despite the fact that washing your underwear (male & female) in very hot water is the only safe way to wash them.  I am a washing guru and got sick of the elastic dying in all of our expensive briefs and panties, I looked for a better way to get them clean without destroying them.  I already knew that Oxi-clean pre-wash was the very best pre-wash for areas that have any residue left by a human. The peroxide in the Oxi-clean may not remove old stains in cotton briefs, but it kills the germs and the product that was left on the clothes. That includes the residue left by all adults in their underwear, blood, perspiration and I am certain any "nasty" material. FYI, if the item is white, spraying extra 100% peroxide will strengthen the pre-wash. I won't explain how I did the various tests, but using a black light showed any "discharges", stool racing strips in young boy's briefs, and blood stains, so that I knew exactly where to spray each item.  After washing in warm water, the black light showed that the residues I found before washing and using the pre-wash were gone.  Keep in mind however, that there are a lot of other things that "glow" on clothes.  Certain clothes detergents leave tiny white spots on some clothes, and I have found numerous other things can leave glowing spots, but it is easy to tell the difference between the odd item glowing and the "nasties" that you would be looking for.   Some Housekeeping Supervisors use black lights to check sheets in a room that has "supposedly" been cleaned.  It is an easy way to see if the top sheet has simply been switched and placed as the bottom sheet, and a new one is placed on top.  I will always bring my black light with me to hotels or timeshares.  Have great vacations!  P.S. When you read the information from Manufacturer near the bottom of the page that fully describes the light, it lists "semen" as something it shows you.

Question 3

can this light detect blood ?

Accepted Answer

The direct answer is "No" it cannot detect blood because blood is not by itself fluoresce, in order to detect blood a material that reacts to properties in the blood can be added to the suspected blood sample, thus making the blood become fluoresce by the reaction to the added material and become detectable. Fluids that are detected by this light are seminal fluid, saliva and urine stains. Also, certain narcotics will fluoresce as will bone and teeth fragments, some spiders, scorpions, quinine in tonic water, Vitamin A and the B vitamins thiamine, niacin, and riboflavin
Chlorophyll makes plants green, but it fluoresces a blood red color, there is a process to separate the material then it can be seen.
antifreeze glows black. Minerals and gemstones like fluorite, calcite, gypsum, ruby, talc, opal, agate, quartz, and amber.
Money glows under black light, Passports and most state ID's do as well. whiteners in laundry detergent.
There are many more items that glow when exposed to black or ultraviolet light. Here is a fun list of other materials that glow
Petroleum jelly, such as Vaseline, glows a bright blue. uranium glass or vaseline glass, rock salt, the fungus that causes Athlete's Foot (supposedly glows orange), 
turmeric, olive oil, canola oil, some postage stamps, highlighter pens, honey, ketchup, cotton balls, pipe cleaners.

Hope this answers your questions and more.

Question 4

If used it to harden clear liquid bondic & needing to look at the liquid to insure I'm aiming at the right place, would I need eye protection?

Accepted Answer

It took me some time to find the wavelength required to cure the adhesive. This flashlight emits UV at 395 nM which should work. I found one reference to the required wavelength to cure UV bonding agents (385 nM - 405 nM). The flashlight emits bright UV light when the batteries are fully charged but the time needed to cure the bondic is so quick that you should be fine. Some other purchasers of this flashlight do recommend having UV glasses on when using this light for long period. Sometimes to error on the side of caution is best. You will find on the flashlight  page under the "Customers Who Bought This Item Also Bought"  heading that many have purchased UV protection glasses also. here is a great link to a study on UV and the eyes https://www.case.edu/ehs/Training/UV/UVsafety.pdf
