Curiosity did get the best of me, so I did get the 20/$20 lights. Just took one out to the dark garage with my Inova. Brightness was about the same with a slight edge to the $1 light, and a slight edge to the Inova in light quality (not enough to pay $9 more though). Switch on the $1 light is actually easier to use and has a very nifty little slide mechanism. Swivel ring loop appears to be very cheap, but I gave it a pretty good bend test, and it did not break, so looks can be deceiving. I am very impressed with what you get for $1. I only wish I could get back my $40 for the 4 Inova's that I had bought.
I do consider what Josey said, and that is always a good topic of debate. For me however, because so many of the items we buy are made in China, it would be hypocritical to simply rule out a Chinese-made light. Also, just because a company is based in America does not mean it is environmentally safe and ethical in it's employee relations. In fact, I would guess that most companies are unethical in this country, due to greed. I am not necessarily referring to flashlight companies but manufacturing in general. Since we do not usually have the complete knowledge behind the scenes of most companies operations, in or outside of this country, I make no assumptions, and tend to buy based on value. I have no knowledge of these lights being produced by abused workers.
Personally, where I work, we sell goods made in the USA, but I would not condemn other companies from using outside sources without knowing the facts or reasons why. The cost in which we pay for goods does not conclude to me whether or not it was manufactured in an ethical, moral manner. If and when I do know all the facts about a company, and it is clearly evident to support behavior against my belief, at that time I cease to support that company. E.g. When I learn of a company that supports gay rights, I make a strong effort to no longer support that company. This goes against my moral values. I personally would rather support a foreign company that has no unethical behavior to my knowledge, than an American company that supports immorality. This said, I will be buying an ARC one to these days.
