Has anyone found a good diffuser for the TK75 yet? Whether it be another brand like Olight, or some easy to get home made part? One of Olight's diffusers fits the TK41 perfectly. But for my extended trip down to Louisianna, I want to bring the TK75 as my only light (other than the LD01 on my keychain). I lost my Olight diffuser in Texas anyway, and want one for the TK75 in stead. The diffuser really transformed the TK41 into a very useable flashlight. THe flood was perfect with the diffuser.
