I just wanted to post that I got my first ever ZL after much deliberation and wish to share my thought so far.The model I selected was the H51Fc. The reason for my selection being that I was looking for a head lamp to assist me while field dressing game. My research on the forum pointed me towards a higher CRI light that would seemingly render reds and browns better than most other LED lights, and in that regard, I would say this light will perform admirably. I find the tint fairly pleasant, and it does make reds and browns quite distinguishable. Though I will say, in the closet test, I lose blues quite a bit compared to cool LED's, but I suppose this is to be expected. Lighter to medium color blues tend to wash out as grey. However, it doesn't concern me terribly, as I plan to use this light outdoors in most cases.The UI on this light is pretty sweet, and I like being able to select which mode I want out of the sub-levels. This is my first electronic clicky, and I must say I do find myself missing the solid snap of a mechanical clicky. That being said, I think having the switch for a headlamp on the end of the light is going to take some getting used to for me, and I kind of find myself wishing I had gotten a Spark at times due to the more common placement of the switch. Either way, I like the light and think it will serve it's purpose. The worst part is, I find myself wanting to get a Neutral (W) model ZL to compare the tint to! I really do want another one for every day use, so I might snag an H501w or wait for the 502 neutrals to come out.... In closing, I would like to thank the forum and it's members for being such a wealth of information. I did a LOT of reading before deciding on this light....PSI forgot the mention I purchased directly from ZL and the turn around time on my order was excellent! I would definitely continue to purchase from them.
