Those LOOK like a great idea. But I have a feeling they only work for a while when someone turns on the lights to "charge" them up for a while. As soon as it's dark, they will go dark soon there after. Remember the old glow in the dark frisbees? Hold them under a light and then they will glow for a while. Then you had to take them in and hold them under a light again. I'd love to hear some reviews. I could see where they might be nice during docking in dark areas, but then again you'd have to hold them under a light to get them to glow before you use them.
Anybody tried these?
Hmm, website says 18 hours of glow with 5 minute exposure to light. Interesting... I wonder how much glow is left after 30 minutes or a couple of hours?
