yes you can get the small security lights with a built in ballast but really they are not that great of a deal in my opinion you could get a better light with a remote ballast the ballast itself can put off quite abit of heat wich is why its better to have a remote ballast to remove the heat from the grow space so you only have to deal with the heat from the bulb have seen the small security lights turned into a remote ballast by taking them apart, but whatever light you decide to use, you should use your sq ft of grow area for determining light size and get atleast 50 watts per sq ft.
