Hi there, I just got a blue/blue astro a couple of weeks ago and it's a beautiful lamp with awesome flow! I found it to be really dim though... it doesn't seem to put out much light at all, and it gets totally overshadowed if you have any other lamps on around it... I've almost finished sun fading the fluid (we're on day 2 of 6 consecutive days over 40 degrees celcius in my part of the world so it's not taking long! 1 more day to go I reckon...). I've always wanted a clear fluid/blue wax astro but I don't even know if they even exist so I'm kind of making my own. It's now considerably brighter and the wax is a kind of silvery white / light ice blue - looks great! I'll post some shots once I've finished fading it... anyway, this is an option if you get one and think it's too dark so good luck!
