i would say go with LED but make sure they are from a decent site with warranty and what not as some places arent reliable. It is usualy worth paying a little extra for higher quality
im my opinion its basically once a new design like a bud booster comes out within a month other companies have coppied it but changed enough so they can get away with copyright and call it something like budbloomer
i hear they are good for rooting and vegging clones but not much else
i have used and evader 135w it set me back a little over £100 but was totally worth it
