^That's actually good advice, I think I often forget as a lot of other people in medical states do, how much different things were before we were legal...not that were all THAT legal anyways.
I think most MMJ attorneys recommend using under 5000k total power, even in medical states. But 2400k is safe for you in my opinion as long as you didn't add the 2400k + all the other equipment in the grow room. The average 6" fan is over 100 watts, everything adds up.
I ran 4 600's in the same room for about 6 months, then added 2 1000w reflectors for about a year, then cut it in half again. As far as I know there was never any kind of suspicion. Most people will tell you as long as you pay your bill on time they don't interfere, which does seem to be the case most of the time.
