The sw40 I offer doesn’t have a violet tint. If you’re seeing violet, it’s most likely due to the coating on the glass lens.
Personally I don’t think the lower output is significant. Most of the time, I use my lights for close to medium range work and don’t require a huge wall of light or throw so lumens is less important and CRI is more desirable for me. Depending on your usage, that might vary.
Put one of the sw45k’s in my Streamlight ProTac 2L-X for fun. I had an LH351D in there which I think I prefer for the larger hot spot and brighter beam. However, it’s kind of a pain to solder the leads back on once the star is seated, so this will probably stay for a bit before I swap it back.
That’s not even a fraction of it lol. It’s a playground, and where I cut my teeth on more involved electronics repair. One of the perks is having a great place to tinker on my own stuff such as flashlight mods.
I went ahead and put the LH351D back in the streamlight; it was worth seeing what it was like, but I’d rather use these 219B’s on other lights.
