Can you determine the lamp is working visually? UV-C such as the 254nm wave length of this lamp is supposed to be invisible to the naked eye.

Yes, you can see it is working. The UVC is invisible, but it also emits just enough visible light, kind of a bluish tint, that you can see it. When batteries are getting low, it gets hard to see, your cue that you need more batteries, or to plug it in.

I do not know if the lamp is working. I assume it is. It does get quite hot when you are using it. The lamp does have a bluish tinge. I've been trying not to look at the light though because it's supposed to be bad to do so. I wish I could test the lamp on some bacteria/virus on agar cultures. Sorry I couldn't be more help.

There will be heat coming from the lamp due to the flow of photons in this portion of the electromagnetic spectrum. However, UV-C may, under some conditions be visible, but you should not look at the light directly at all. A photometer can be purchased at a very reasonable price that will positively confirm the devices function and they can be purchased on Amazon and can tell you how well your device is working. I hope this helps.

I think probably not if they couldn't see the 850nm light. Most cameras filter out these wavelengths I believe, at least mostly. I would think they night goggles would see it though.

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.

No, don't think so - don't recall seeing anything about that either on the lamp or in the manual

It is an ultraviolet light. It works. The light makes the chemical work. I did have to look up the product and print up the instructions because it did not come with any. It does work very well though.

I don't know. My tv has a fuzzy picture on some channels, but I'm not sure that has to do with the lamp. My tv is still working.

This light is invisible! You cannot tell if the power is on or off by looking at it in the dark. You will need a IR camera to tel if it is actually functioning.

You can see brightness from a "light" of a lamp but cannot see objects - occasionally a shadow. Nothing significant. Normally you can not even see shadows.

Yes, you should be able to see it. Just to be sure, take it into a dark room. If you can see a light blue glow then the UV bulb has gone bad.

I have a 395nm Flashlight from Cybertech with 9 UV LEDS (Its a 3 in one with a reg flashlight, red laser and UV ) it will detect dry stains, but not wet ones. There is a good bit of purple haze at 395 though it works. 365-375 shows awesome, and I am waiting to test and make a comparison with a 380-385 one

If you have the knob in the on position, and you have the batteries in correctly, then yes, you'll see it just like a laser pointer. Look in and see if you can see a red glow without pointing it into you eye of course. If you see a red glow inside, but no laser pointing out, try adjusting the beam, it may be way off and pointing at the inside of itself. If all of the above is ok, and you don't see a red glow inside, then it is most likely defective.

Good afternoon. The light has a dim light and a bright light. When no motion is detected the lamp glows dim and when you get near them they go bright. You have a dim light at all times, and goes to bright when needed. I have these lights and they are the best! Almost going on two years now and no failures.

There is a little door on the side of the unit that opens up. You will see the light from the UV bulb shining through if it is on. (Read your manual!)

Yes I can see the UV light . My room is 13' x 15'. I turn the UV light off at night

It has the same kind of screen I always see. I just turned my lamp on and it I don't see a reflection of the lamp on the computer screen. Hope this helps.

The effective range of this style of UV-C lamp is quite small and the bulb can cause eye irritation. This is why the lamps all have fans to intake air then irradiates bacteria within the sealed chamber.

I'm not sure. The lamp is rated 4000 hours, 5000 hours in Eco-Mode. Maybe your not opperating in Eco-Mode?
