Interesting to hear your experiences with the Glo-Tubes. I was thinking of buying some of these for myself as well. I was a little surprized to hear the blue is not as bright. The blue-ish LED lights I have a some of the brightest when compared to their siblings (CMG Infinities in my case). But the CMG's I have are the teal blue/green color, not a dark blue and maybe that's the difference. I was trying to find the color Glo-Tube that "stands out" the best at night. The most eye catching, which may not equate to the brightest. I'll get around to deciding and actually buying a Glo-Tube one of these days.
