I received my 3 speed DD SST-50 drop in today.
I swear after I placed my order I had shipping confirmation 10 minutes later, or so it seemed!
I ordered this dropin on Friday, as well as a FM 1 x 26650 tube, and a IMR 26650, and I even found a 6P head on the marketplace.
They all showed up today, I got four packages. (Unfortunately my wife checked the mail today and not me.

)
This dropin is very nice. Actually this is my first non SF dropin, other than the Malkoffs I own. The emitter is just about perfectly centered, if not perfectly centered. The quality is nice, and the orange peel on the reflector is to my liking as well.
I had to charge my IMR, so that took like 3.5 hours. In the meantime I loaded the FM 26650 tube with a AW Li Ion 3300mAh C cell I had laying around. I dropped the drop in in. (Funny sentence eh?) I then clicked the button, wow. The beam is very nice. A nice hotspot that covers 30-35% percent of the total diameter of the beam. I could be wrong, never was good at geometry. And it was bright too! There is no doughnut or square or any dark artifacts in the center of the beam. If you want to split hairs, my example does seem to have a slight dim ring around the corona, then gets brighter in the spill. LOL, you would NEVER see that in real use, thats looking at a white ceiling.
On the lower levels I dont notice any PWM flicker, and I am pretty sensitive to it too. I find the three levels spaced well, but for my use, i could just use a two stage with high and low, since low isnt that low. Low is bright enough for 95% of all tasks, my tasks at least. I would guess low is 25-35 lumens.
OK, my IMR finally finished charging.
Pulled out the Li Ion and put in the IMR 26650.

This thing, seems anyways, way brighter on the IMR C cell than the Li Ion C cell.
Wow, the beam is gorgeous and lit up my yard very nicely. The throw is good, but not great, but still better than I expected. With the big focal spot the SST-50 has, I didnt expect throw. I must say though, I think it out throws the P7/ MC-E, while maintaining brightness (brighter?).
All in all, for the price, this is a WINNER!
Good job David, I am already thinking of a SST-90. You said it starts at 800L?
Hmmmm, must resist...
