I'm not gonna knock the Solitaire. I am a Mag fan. It is a quality light that has never failed me. I own several. But this lil Nano puts it to shame. On every end of the spectrum. Size, $, beam strength & battery life. Here is a lil side by side comparison.
This is my kitchen.
It's not much but it will work fine for my comparison. I have the camera set back 12-13 ft from wall. So the beam is aprox 15 ft from wall.
Here is the Solitaire
This is a brand new battery. Stock bulb. Again, aprox 15 ft from the wall. It is adjusted for the tightest beam possible. Not terrible for a pocket/key chain light. It will get you around a room or out of a drain in a pinch.
Here is the Nano
This is with batteries with at least 3 hours on em. I love it. Bonnie loves hers. Again I am aprox 15 ft from the wall. Both lights were shown from the same position & the camera never moved. What a difference. This does not adjust so it is only a flood. But even so it out shines the mag on both(flood/distance) with only one setting. It is aluminum, has fine threads & an O'ring. Very tight tolerances, head is smooth & the batteries don't rattle. But they are easy to remove. It runs on 4 LR41 watch batteries. I found a site that sells them in sheets of 100 for $5.95 & they shipped them for free. So that makes this a very cost effective light. The clip is very sturdy but is easy to remove for relocation. It's so lite you can hold in mouth with no strain. According to the packaging it is weather proof, 10 lumens & last up to 8 hours.
I guess I should have given this it's own thread since it kinda turned into a review. I give it a 10 out of 10
