Based on the photos this light looked like a great addition to my collector's room. Unfortunately what they don't tell you upfront is that you need both 3 AAA batteries PLUS a 5V DC USB AC plug (not included). If you thought you could just run it off the plug, that's also wrong. You must have batteries installed for it to work as well. The other issue is the terrible illumination this puts out. It only gets to what I consider a decent brightness when it's on pulse, but I personally don't want it to pulse. Overall I feel it's a subpar product that I regret purchasing.
