Quick Summary: Protac 90 modded to floody plus magnetic base.
The Protac 90 has both an outer lense and a TIR. I wanted a floodier light for my right angle protac (I also have a 1L-1AA) so I took the head off to see what was in there. Turns out, there is a rough aluminum reflector, a TIR, and an outer lense. I took out the TIR and it is floody with a faint hotspot. Perfect for what I was looking for!
Also, I went to HD and grabbed a 3/4” Neodymium magnet (comes with sticky patch) and placed it on the bottom of the light. Just testing if I like it for now. The internals of the Protac 90 has a metal washer around the spring which is relatively far from the base of the cap, so I didn’t try placing a “donut” shaped magnet inside for compatibility. If someone has experience with removing this metal washer, please leave info in a reply.
I couldn’t get the head off of the the 1L-1AA.
Side note… The TIR for the SL HL4 can be swapped into the HL5-X (and vice versa), but I would only recommend that if you want a straight out flood light (different LED’s for different beam pattern). I did not check the beam pattern of the HL4 with the HL5-X TIR, as I like the HL4 as is… I would assume it would be a narrower hotspot.
Sorry, no pics for now (strapped for time).
