What model specifically do you mean?

You could get very good results with the lamps about 5 centimeters from the PCB. There are considerations about parallelism of the light emitted when it is too close, but commercial units are built that way and work okay for most work. You could study and build a collimer for the light using different methods but I suggest that you try first with the proper lamps and see for yourself the results. You won't be dissapointed.
