I picked one of these up on the weekend to give it a play around, and I have to say it's pretty impressive.
There's three modes on it. Nightlight, which is a small orange light, one tube, or both tubes.
It runs on 4D batteries, and it has a bit of weight to it.
Is what she looks like.
And this was a 30 second exposure, with both tubes (or was it one? I don't remember...)
