I am not the one who wrote the review but I think it takes 12volts. Plus I have one in my case as well from the same guy. It looks great and there is not to much light. I would have to say that there is no such thing as to much light. I am 24 years old so I am an adult. Sheesh don't I feel good. Who know maybe 24 is still a kid in your eyes. i dunno. If you have room for a workshop you should put one together. They work great.
