Okay, so I added DC Fix to all my Convoys, and went for an hour walk last night..
(that's probably the reason why I got a bit sick today)
Simon basically said that the lower CCT is likely because of the reflector.. strange.. why do I measure 4000K on a 4500K LED.. shouldn't that be just sold as 4000K? lol.
Some more observations I made.
Still, it's hard/impossible to say which LED I like.
Here's (probably) my last summary of thoughts.
- Testing 10+ lights at the same time is probably not a good idea..
- Whatever way you go: from cool CCT to neutral CCT, from low CRI to high CRI.. the differences are obvious. And that's the main thing you'll notice. At 1 point I said: Hey, I like this beam.. but then realized I noticed that I didn't like that beam too much when I compared it to another light a few minutes before. lol. Just let that sink in. And that happened a couple of times.. What you compare it to has a lot of influence whether you like something or not. Most of the time, if you have a nice beam, you can get used to it, even if it is not the perfect tint/CRI etc.
- My personal preference is definitely going towards the cooler lights, somewhere between 4500 and 5500K, and likely towards the 5000K+
- If I had to choose between a low CRI with a nice beam vs high CRI with a bad beam.. I'd choose the former.
- DC Fix really "fixes" many beams. Especially if you had some rings/tint shifts, this is the way to go. Get some from Boaz : https://budgetlightforum.com/t/-/35838
- I'd rather prefer Low CRi with a nice neutral-cool white beam that high cri warm beam. (beam with DC fix, and a Nichia without DC fix in a convoy s2+ with smooth reflector.. not a good choice)
- I don't like Nichia 219B or 519A in a Convoy s2+ with smooth reflector for walking outdoors.
- Getting the right tint might be more important than high CRI
- There's just too many variations why a beam can be nice, and CRI is just one of them, and probably not the main one.
- I got 3 of the same LEDS (Nichia 219B 4500K) and all 3 are slightly different. So even if you say: you should get ABC because that's the nice LED out there (well, some people would just say: you should get High CRI..lol.) The person could actually receive a different tint, and think you are both talking about the same thing.. but 1 is not the same as the other.
- If I had to choose between a 'greenish or a pinkish' tint, I'd probably prefer the pinkish
- Get an Opple :D It's great to be able to measure the CCT (temperature) so you actually know whether the LED you got is actually producing the CCT you thought you would get. (That's why I like the Opple Light Master a lot!!! Greatest gadget for flashlight enthusiasts made in the last couple of years)
- But what I really noticed is that the beam shape/spot/spill is one of the most important factors for me, using it outdoors. Even with a greenish tint, a smooth and nice beam is so much nicer to walk with. Last time I didn't use DC FIX (lookalike), and each beam was so different, that it was even more difficult to compare I think. The beam shape influenced my perception of how I liked a light or not.
