questions about fluorescent tubes

[sonycrr]

shopping around to replace the bulb on my tanks.
36"in aga single strip light.


i notice some lights come with reflectors on them. does that make a difference in brightness?

want to get a 10000k or 18000k bulb.
any one have a pic of either light on their tank? =D
tried searching in the pics section. didnt get much.

Reflectors make a huge difference. I understand that good reflectors can increase efficiency >200%.

Coralife 10,000k is a nice white bulb. I ran one when I had my cichlid tank and the colors looked pretty good. Sorry, no pics though, my camera blows.

thanks for the pic
your tank and orange walls go pretty nice together, nice contrast. ha

do you know how your tank would look different if it had a 10000k light?

thanks

with a 10,000K light it would probably look a little less blue-ish.

18000K bulbs are white with a hint of blue.

10,000K bulbs are pretty much pure white.
