TrueRMS, nice job with the WF2, looks centered to me. Looking forward to seeing some beamshot in the X6, I don’t have “flats” in any light yet.
My mod today, an Olight i5T.
I like and carried the Olight i3T since it first released, so I was excited when the i5T was announced and picked one up during the first Olight Covid-19 charity drive. It was pretty much what I expected, a larger longer running AA version of the simply forward tail-clicky 2-level i3T, nice. The only thing detracting from this excellent light was the green tint-shift, so I decided to tackle an emitter swap.
I replaced the original cool Osram P9 emitter, which is a nice clean/cool white tint by itself (when viewed without the optic/lens in place) but as mounted in the i5T with the optic, suffers from green tint-shift. Perhaps it was an action-reaction thing with the cool white because I decided go in the opposite direction with a warm LH351D 2700K emitter for this reflow.
On the photo left is the view of the inside of the i5T with plastic lens and optic removed. The lens is press-fit so there’s no easy way to gain access without sacrificing the lens to get at the emitter inside. Similar to the i3T, Olight once again used a wireless post-through-the-MCPCB method of mounting. Clean looking but tricky to re-work.
On the photo right is the final light with warm LH351D installed. I salvaged the lens the best I could with repairs using optical epoxy. I have a glass replacement lens on order and will replace it later.
This was my first installation of such a warm emitter. For those desiring incan-like color temperature, the LH351D did not disappoint. Here is a comparison of the 2700K LH351D (on the left) with a real Surefire incan P-61 (on right); a 5000K neutral is on the bottom between the two for reference. The wider hotspot from the optic gives the illusion of the beam being slightly warmer/more orange than the focused incan hotspot. Frankly I found it a little too warm and may opt for something in the 3-4.5K range when I replace the glass.
