The Model 60 is roughly half the size of the M64. The M64 mounts using a single M8 bolt (included) on pivoting bracket. Here is a picture of the mount. No front lighting or addtional lighting. The lights have no cutoff. If you look closely at the picture, those are stars in the sky! This is a long exposure (~5 sec) picture to capture all the light output (and it still does not do it justice). With current led technology a 3600lm spot in the size (55mm diameter) of a model 60 is not possible. Here is the same shot of a model 60. M64 Thanks for your business Bob.
