Do these detect UVA rays indoors, or do they only work outdoors?

I had a slight reaction to light indoors, but for best results, go outdoors. The sun makes it so much more fun, and fresh air is wonderful, too! ;)

I do not know. However, windshields do block UVA rays. I do not know about the other rays.

They are not advertised as UVA/B protection, that would lead me to believe they are not.

I've owned these for several years now. I won't say these are great, but they did last several years. They just recently died on me. I haven't removed them yet and haven't checked if they're really dead. Yes, these are real UV lights and lights up 'White' colors in your motherboard, and any UV reflective component that you have installed. I have UV reflective SATA cables (neon green), and they give a pretty good 'Ghost' light effect. So, I'm also certain that it would do the same with UV reflective pipes, etc... And since these are 'Black Lights', don't expect it to light up the inside of your CPU. They are not bright. It's not the purpose of this item. I've owned these for several years now.

I did a lot of research before buying these and I was told they do not. The package says nothing about UV protection. I am 99% positive that they are only to protect the eyes from flying darts.

You see ever so little of the uv light from the back bottom of the unit but it is certainly not a concern. The main light seen is the blue led light on the front indicating the unit is on.

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

No, they only work in room size areas and would really not have any effect when used outside.

UV is on when the button is in, off when it's out. When it's on there's a light that's kinda hard to see through the front inside.

The works with sunlight and long time in black UV light. Best with sunlight. Will work both behind a window and outside.

I've got them in outdoor flood fixtures (the kind that have metal shades) and they work very well. They've been rained on a number of times while both turned on and off.

No clue. We just use them visually to monitor our residents at the comfort care home we run. Sorry.

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 have these on my Glock 19 and in the house under normal light they dont really glow...But, when you walk outside on an over cast day or a sunny day they really jump out atcha!! You would swear they have to be under battier power but there not. They really work great outdoors

They block and protect your eyes when using Black Light/UV. They would only enhance when using the "light" as far as contrast on urine.

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. There is a button on the top surface labeled UV. That button contols the uv light being on/off.
