Sylvania aquastar has a little more blue in it and their coralstar is very blue. If you want a cheap option try using the diode type christmas lights. I bought a strand of 80 and folded it up in four foot sections and stuff it under my lamps/over the cover glass to use as moonlight to watch to night life. It does not give that much light but with a few more strands and some mirror backing(alumium foil) it could look really cool. Toss in a strand of red and you get purple lighting. Oh the Thinks you can Think.
