Hello all.
I'm researching the 6500K 250 W Iwasaki lamp.
I've read that the R version is a little bluer. Supposedly it
measures in closer to 7200K but after reading some reviews and seeing
a picture of a reef tank lit by one, I'm concerned about it being a
little too yellow. Some sources say that it is THE perfect bulb and
has great color. Others say that it's too yellow/green.

Anyone have any experience with this? I'd likely supplement with
actinic CF anyway but would like to do so minimally.


Thanks,
Erik
