Can anyone confirm for me the difference (other than the number of modes and price) between these 3 P7's...? I have read every post in this thread and i am still unsure

1. MTE SSC P7 900-Lumen 5-Mode Super LED Flashlight (1*18650) - Price: $39.51; DX sku.12060
2. MTE "P7-D" SSC P7-C 5-Mode Memory 900-Lumen LED Flashlight (1*18650) - Price: $47.99; DX sku.16092
3. MTE SSC P7 C-Bin 900-Lumen 8-Mode LED Flashlight (1*18650) - Price: $42.96; DX sku.13060

Thanks!
