    LED is always going to be more efficient than cfl , and vegging doesn't require nearly the light output that flowering does, so try it. Ideally you want something with more blue light for veg, so you may see some changes in stem and leaf growth. You would never be able to flower under something like that lamp, but should be okay for seedlings/clones for the very start. The red may actually promote rooting.

    That bulb is really underpowered.
    Better go to homedepot or a local equivalent and get some regular 100 watt equivalent bulbs.

    Thanks, the light is only supplemental for a few hours of light after sundown going to add a 100w 6500k bulb. Would a bulb that gives off uva/uvb be helpful? I have an unused bulb from a reptile tank that gives of these.

    UVA/B is only helpful during flowering in not very big amounts.
    Small amounts increase THC production (natural sunblock for the plant), but too much will cause damage.
