LOL the other lights I use are usually not in use untill I have a reason to use them specifically.....and in fact when I am blooming something I go all the way to 2200k much farther into the red to get the most blooms I can ...in fact my phaius sat under a 250 watt hps last winter exclusively and produced If I remember 35 blooms on one spike on its first bloom.
THe other lights I have that are not 2700k are a metal halide 100 watt and a 85 watt 5000k cfl over 10 feet away on the other side of the room not exactly close and in reflectors to aim them right down on the table they are to cover......
Then I have 1 250 watt high pressure sodium that would be 2200k and much farther into the red and it is at least 5 feet away from any thing except the phaius it is hanging over again this winter...which is in spike again with three spikes this time ....a picture of it here as well ....I dont think either of these would be considered weak and I expect the blooming power will be excellent on the phaius this year as well .....It is always better to try for a balanced mix in lighting but 2700k is not that red and if the wattage is high enough will in fact do a very very nice job....in fact I have not found anything I can not grow under a 65 watt 2700k cfls it is not the most effecient and not the most balanced but it will in fact work very well if it is a higher wattage.
Being the cheapest and easiest to find they are what I use and I find they do a great job.
