105 watt clfs put out total lumens of 6,900, so if you are going to use these to flower with you are going to be seriously underpowered, during flowering a plant required at least 10,000 lumens per square foot in order to flower sufficiently but even then they wont be that great a 600w high pressure sodium puts out 92000 lumens, a 400w hps puts out 52,000 lumens these are needed to get great results but if you thinking of stealth then you need to look at a 200w envirolite or cfl to flower with.
