In 30-plus dives I haven't noticed an issue yet, and I'm hardly the easiest on my gear . But I would be curious if I could remove both the spring clip and the plastic fitting around it and just use the steel post, but I'm not going to ruin a perfectly good light to find out.
Peace,

I have uk sl4 and sl6 that I upgraded with a Cree drop-in. I wonder how the Photon Torpedo and Dorcy lights compare to them? I think they're all rated around 220 lumens.
