is the uv light separate from a regular light? uv as in detecting phosphorescent items?

There are three LCD lights in a single row on the bottom of the battery casing. The center one being the UV light. The other two lights are for regular viewing. The control switch is right next to the row of three lights. It has a single three position slide setting switch. The middle position being the off , the up position being the UV and the down being the regular viewing lights. The lighting is very sufficient I would recommend. I use mine on a regular bases. Hope this helps.

You should always wear protective classes when dealing with UV, specially when there is no oher light source, my eyes get strained when looking for scorpions in pitch black nights, however, for pet urine detection at home would be alot easier and you should be fine for a few seconds

Yes, the UV light turns on only when it senses water flowing. Once the flow has stopped, the UV light turns off.

No, there are different coloured light versions each is only a single colour.

Hi Kristi, I googled the product information and it says the light emits Blue Light but when You have it on, it appears like normal white light to the human eye. The product description says it does not emit UV light. This product does help SAD. I have one. Enjoy and I hope this helps.

My thought was yes. UVC is a short wavelength and that is why it is blocked by our atmosphere. So it is easily blocked by glasses and probably plastic as well, especially plastic that we know blocks UVA and UVB rays. Here something from Wikipedia: Ordinary glass is partially transparent to UVA but is opaque to shorter wavelengths, whereas silica or quartz glass, depending on quality, can be transparent even to vacuum UV wavelengths. Ordinary window glass passes about 90% of the light above 350 nm, but blocks over 90% of the light below 300 nm.So with resonable confidence yes they block UVC, which is what germicidal lamps put out. Watch out for your exposed skin though. My thought was yes. UVC is a short wavelength and that is why it is blocked by our atmosphere.

yes, there is a UV light, it is basically the same as the one with UV/normal ink nibs, and it is compatible with both of those nibs.

UV light indicator is located on top of the unit with little glass window. If it is too bright you will not see the light. Make sure you got the right model as some of them do not come with UV lamp.

Led I don't know but it works with UV light...I don't know the difference between the two

It blocks blue light regardless of it's source, artificial or natural. And I just got my UV meters out and for instance the total UV (UVA + UVB) measured was about 1.6mW/cm^2 and UVB alone measured 113 uW/cm^2. With the glasses placed over the sensors they measure 0.00mW/cm^2 and 4uW/cm^2 respectively. The UV meter also measures 4 indoors so I think the that is a calibration issue and it is really 0 for UVB. UVB is easily blocked by plastic even if not tinted. So I would say the answer is yes, it blocks UV and blue light.

No. LED lights and HID lights (HPS for example) emit a completely different UV spectrum. When flowering, HPS is fine by itself-as long as it is powerful enough.

Yes -- it is to an ultraviolet light that is a "tube" (water goes through the tube and the light bulb is encased). It's to help kill algae. Our light bulb is not part of the filter. However, we have had great success with this purchase. Hope this helps!

You hafta trust that red light. The UV light has to remain sealed,it would cause a lot of damage to you if not. Like skin cancer,and possibly end up permanently blind.

Yes I think so , not sure if my tech uses a uv or led light. But I think so. Sorry hope info helps.

Organic material will be detected by the UV light regardless of where it's located...so, yes.

I agree with the others that you may get a glimpse of it; it's inside the appliance. I don't believe it's exposing me to any UV light. It's the light on the front control panel that is BRIGHT (and why I covered it with black tape/paper so I can sleep)

I have used led, but it doesn't last as long as uv....best to use uv I think
