right on mr limpet...
get several daylight 6500k cfls of the highest wattage you can find at walmart or home depot for vegging...
you'll get much better results..
altho these cfl security lights are pretty good for flowering if you change the bulbs to warm white... i'm using these cfl type floodlights with PLC 4 pin bulbs for flowering and theyre workin real nice...
heres an example of mine at work and their results(in my other ghetto grow room..waiting for some lighting improvements at the moment)....The side CFLs supplement the Security light.. the security light has 3 26w 4pin PLC bulbs in it which were daylight 6500k, and i use those for vegging, then changed 2 bulbs to 26w warm white...The 1 daylight CFL was retained to even out the lighting spectrum color to a more natural spectrum
