Got a pair of Gene's drop ins last night and put one into a 3D carried in my car.
Installation was easy- just a little compression of the the copper outer ring and it slid neatly into place with a good fit.
I also own one of Gene's 3D conversions that are no longer listed on his site.
Because both are supposed to run the SSC at about 1A, a simple comparison seemed reasonable.
Tailcap current measures were 1.06A on the conversion and 1.18 for the drop in.
Beam comparisons are more about differences in the leds and reflectors than obvious power differences. In my case, the drop in is slightly whiter than the conversion that focuses to a slightly tighter beam. There is no obvious output intensity difference and both have the long reach expected. They handily dispatch the Terralux drop in running in a 4D mag (tailcap current measures at 0.55A for the Terralux which could probably be rengineered by the maker to run at somewhat higher current with a little bit of effort directed to heatsinking and the use of a cutoff reflector)
Summary- Gene's drop in works as advertised and isn't any sort of performance drop from his prior conversion light when used in a 3D.
Mine fit perfectly but variations in MagLites combined with the design of the drop in may make some easier to fit than others.
