hps V envirolights

my local electrical retailer sells both hps and those huge envirolight cfl thing - just been looking and cant find the thread about these type of light.
im just wondering if any one has experience of these type of cfl? are they any good?
i notice he sells the blue and red spectrum ones and was wondering if they are any good

any comments welcome

dude the best idea would be a combination of both. cool blue light for veg and red spectrum for flowering. enough cfls can grow some damn nice herbs, but nothing will be able to beat the power of an hps. i woudl definately have cfl side lighting as well though, the more the better.

for veg a blue evo CFL would be bad, for flower a HPS rules, and to compare those two types it is like comparing a .44mag with .500s&w mag, each has it purpose but both aren't good for everything
