Me to! I have found their xhp35 and xhp35 HI pretty safe tint wise, also their xhp50(not the .2). However the xp-l2 hi cri and 4500k can be overly yellow, the xhp50.2 i wont try out with the potential of too much yellow.
I dont care much for their AA lights really, not much point imho other than anyone who does not actually want to run 4.2v cells(just want to use nimh). Their 18650 lights are very compact, in fact close in size to typical 16340 size lights. So for me personally, no point in AA as the 18650 are compact enough with far more benefits(run times/out puts).
My sc5c mkII 4000k was not very nice on my eyes, i tried and tried to like it………………gave in. The sc53w which is also the xp-l2 but 4500k is tolerable.
My fav so far is the older sc62(like the design) with the luxeon T 85cri, super nice 5000k and dont care that it is only 320lm on H1. In fact , my most used is 145lm H2 and works well for most general tasks.
I dont care much for clip on clips(just hate them as they are usually junk) of the sc600’s, much prefer the secured sc62/63/64 design there.
Quite impressed with the xhp35 HI 4500k, liking that as quite a punchy little thing. Also the xhp50 5000k in the plus(both mk III as i dont want to chance the mk IV with odd little gremlins and even more potential yellow of the xhp50.2)
Some AA size lights for size comparison
18650 sc63w/16340 PK PR1 and 16340 HDS rotary hi cri
Little size line up, all 16340 up to the black D1, then 18650 till the sc5c mkII AA on the end
s2+ thrown in for size
all 18650
Overall ZL are pretty awesome, not much to not like for me. Very light(often the actual 18650 feels about the same weight as the light itself), UI i like, newer UI is better as you can program G6 and G7 to what you like of the 12 levels. So you can swap about or have all the same level to act like a single mode light. Its a way of getting around the pre flash when double tapping for the M1 /M2 levels, but flip side is it upsets the press/hold and advance through modes. Press/hold is low/med/high usually(G5), of course if you have a high level set in the L1 , then it will flow as programmed.
The PID is pretty trick, it manages heat like no other light i have experienced(inc the D4 clever UI but the D4 is 3x the lumens!!! so has to be aggressive ). The step downs are very hard to spot and the light never gets hot, just quite warm. Only when you step back up on a high level can I actually tell its ramped down! That is actually looking for it as well, not in actual use!
The ano is 2nd to none, its tough and seems actual HA unlike most chinese lights that claim it. It reminds me a little of the surefire of old HA. You drop it, hardly a mark compared to other so called HA III i have found.
Comments are all subjective, so please take with a pinch of salt, as what i like you may hate They are not perfect, but for a super light weight compact 18650 light, they come close in many ways. Tint lottery is real! By staying away from the horrid(subjective) xp-l2 of theirs, your in for a little more chance of a win
