Dale - the Shocker is 106mm head diam while this light is 94mm. The Feniz TK70 using D cells was also 106mm head diam. I think RIC is selling a re-branded LusteFire triple (or LusteFire is the re-brand 
), because it was measured at 93 mm here: https://budgetlightforum.com/t/-/22740. WallBuys selss it for $74 here: http://wallbuys.com/Product/LusteFire-3XU2-X3-3-x-XM-L-U2-3000LM-5-Mode-White-LED-Flashlight-Black-3x26650--10997, but it's listed at 92mm there.
The distinctive body tube and tail marking match up about perfect. Still for $65, pretty good deal, but you can get a Shocker host for $65.
