Lighting

[fencer]

I have been running 10k's and they are fine. But I find that the colors from acros do not come out as well. I have also wondered what is the best comprimise between growth and color. It looks like by the poll 14K's are the way to go. As for consistency of colour/temp, I would think all bulbs degrade with time and is highly dependent on amount of use. I suspect with most bulbs output efficency drops less than 10%. One of the electricans at work say less than 2% over the year. Sanjays site is excellent, I don't knoiw if he has an upto date chart of various bulb performances. I myself have gone to replace after one year plan. I am going out to buy some 14K's.
