the main flaw with this light would have be trivial in the recent past . compare to other way of provide light , even DeWalt way , this be not a effective solution . I buy this to have a work light that also use the 18v power pack from my various DeWalt 18v tool . so far so good . but it really burn some power , it get quite warm and the light do not last as long and be not as bright as you would hope . I also have the DeWalt dc527 fluorescent light , it provide a much better work light , last longer and be easier to use to get light on you work . by comparison to the dc527 this be a uneven and yellowish light . this be more compact than the dc527 though , and it provide better range , fluorescent provide more white light , but only at limited range .
