hi, is this any good?

hi, im new here! ive got a few small plants on the go at the min, growing in soil on my window sill. they aren't getting massive and i think its down to the lack of quality light available.
i was thinking about getting some sort of cfl set up, but i found this at work Britebox SAD Light Therapy Shop : Products : Lightboxes : Britebox
anyone know if it will be of any use? it says it has 10,000 lux and a 6400k colour.
will this be ok to use or pointless as it could save me having to spend out money i havent really got at the minute!
cheers

use CFL's....the 'sad light' is useless

thanks for the reply, any reason as to why its no good? i thought it had the right output for the veg stage? im a complete newb here so any info is useful!
cheers

if it's free?...go for it. It would HAVE to stay on for at least 18 hours a day

it is free and i can kep it on 24 hours a day!
