please see my review on DeWalt DW 9043 bulb , as most of that apply here . bulb work great , but run very hot . Lens very hot , after 2-3 seconds touch , reflector about the same . metal hinge\/holder too hot to touch . some plastic smell in first 10 minute inspection . check again at 1 hour 5 minute -lrb- total test time -rrb- and still the same . no scorch or melt plastic . a winner ... UPDATE april27\/12 : still work great with normal drop and bang , lens heat not a issue ...
