I got a PFO Mini 250W HQI PEndant System with a 10K DE bulb for my 29. I use no other light supplementation any more (MH melted my casing for the Actinic support and have not replaced it). This light has great color without support. I also like the narrow path that the light has. It covers my entire 29g excellently! I have seen some pendants that have a more spreading light, which is excellent for a larger tank, but not what I wanted for the small tank I was lighting.

Good luck! This is a hard choice to make! Way too many options out there!
