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,

Well, that is a hard question to answer, because only you will know if
it is to yellow or green for you. Personally, I don't like the looks of
a tank that is lit by the eye bulbs without lots of actinic. But if you
want fast growing corals, it is one of the best bulbs you can get.

With your 65 watt PC actinic it will still not be a very blue light,
since your 65 watts is not going to do much against a 250 watt MH bulb.

Now the Eye bulb is a great bulb, lasts a long time, puts out lots of
PAR, just not real pretty, but its price and life and PAR output make it
a very popular bulb for coral farms.
