TK41, expensive for a budget light. Powered by 8 AA Eneloops or 8 alkalines, this thing throws like Randy Johnson.
Trustfire F15-love the looks and the throw, mine has some soldering issues that I need to fix. Also, note the diameter of the C8 style head compared to the TK41
Trustfire T2; yeah, my favorite by far, I love the side clicky switch. Strickly an 18650 light
Trustfire F23; cute stainless AAA light, mine has a very stiff clicky but great throw for a small light, runs on AAA or 10440
Trustfire Z1; a Cr123 light, great conversation piece. The clip will leave it on your belt or in a shirt pocket in a perfect position to illuminate your work. Will run on rechargeable Cr123''s as well.
Yes, I could be a Trustfire spokesperson. I like the bit more bling they have compared to the plain vanilla lights.
I like the looks of the F15, was disappointed that the soldering of the driver to the side of the pill was broken. Looks like a pretty easy fix, if I owned a soldering iron and knew how to solder...but for now it does still function.
But look at my comments in a separate thread; you will be hard-pressed to see much difference between the hotspot of your Palight C8 and the F15 when you get it. Same body, same sized reflector; better hotspot with the Xp-G. More coverage with the XM-L.
