New MH 250w 67k Seems like a lot of yellow ....

I was in a local fish store today, and started talking to the owner about
lighting. I was surprised by his almost violent reaction to MH lights. He
claimed that MH burns way too hot, and that he set one up in the store and
had to take it apart because he was feeling the heat about 5 feet away. He
also claimed that a person with a MH tank HAD to own a chiller, as no amount
of fans would cool the temperature of the water in a stable manner.

Since I've never seen a MH light, is there any substance to what this owner
was saying? In my mind, I was thinking this guy either likes to tell some
really streched out stories or he had a couple bad cooling fans ...

Thanks!

10,000K shouldnt have too much yellow

seems 10K is below the scale and would be some kind of black or grey

some bulbs will be different the rating is given to the overall bulb
coloring so it could
have yellow and a blue and no white (streaching it there) ive used a few
different bulbs I
am liking the 20,000K bulbs and ive liked the sunburst 12,000K bulbs in
the past. neither
have any noticeable amount of yellow, there is a white and a blue
depending on how far
from the bulb you are.
