yep, that's good to start out seedlings. would get you through the first couple or three weeks. might want to check out the big ass sylvanias 55 watt or so, which will give you about 8500 lumen per bulb but best be ready to vent some heat out and make sure you vent plenty of fresh air in, the exchange is very important. the hotter the source the more you want air flow directly on those plants. not pretending to be any kind of expert or anything. the greatest thing you can do to help cfls is build cheap reflectors, shoe boxes folded out and covered in cheap ass mylar will work just fine. duct tape straightened out hangers to the back of them to get the shape you need, catch that light and get it right back down on those precious babies......just remember......air flow, air flow, air flow
