1. I'd prefer the od of the ring to be "flush" with the body of the preon (although not a deal breaker).
2 and 3. The aesthetic of the eiger clip is good with me.
Re: Doesn't peripheral vision favor cooler than straight on?
I got a Preon 2 Neutral, and I'd rate the tint as "decent". Comparing it to my only other R4 neutral, a DQG II Tiny, I much prefer the DQG tint.
I'm also looking for a medical light, in a penlight format. It should have the following: multi-mode with a low mode for pupillary reflex (3 lumens or less), high CRI led, sturdy pocket clip, and a clicky. A 4Sevens Preon 2 would be perfect if it had a high cri led. Any suggestions?
I'm also a fan of this light. I got the neutral XM-L E03 and it's a great tint, the beam is really floody. I'd love to see a pocket clip made specifically for this light.
