Yes they advertising “more lumens” , but they don’t write in advertisement: “crappy blueish, low color rendering, eyes damaging lumens”
What i can say: DO NOT BUY SNAKE OIL
Low CRI is fine if you just need to see where the table is.
but I promise you that wood is not actually green, like the Low CRI shows it:
Low CRI is fine if you just want to see the food, but, I would rather see the color of the food Im eating.
Low CRI is fine if you just want to see the Green Bear, but its more fun to see what color he really is.
one of the most misguided ways to use Low CRI, is to look at leaves. It makes them greener. From this some people will claim that the Low CRI LED has great color rendering… NOT!
where Low CRI really falls down, is in its lack of Red output
Why do people buy lights with Low CRI?
because they dont now any better, or plan to swap the LED to High CRI
Olight have good drivers and it have nothing common with color rendering , just HI-CRI led have a little bit lower efficiency. If 70cri have 1000 lumen output of crappy color rendering light , so 90cri have 900-850lumen output of close to natural color light.
Not really important for what I use my flashlights for…which is walking the dog after dark….in the fall and winter when it gets dark so freakin’ early. Don’t need a high Color Rendering Index since there won’t be any color around here for the next 6 months, just wonderful shades of grey and white
I’m generally very happy with my Sofirn SP40 and Manker E03H which I use most often for working on the car or on electronics. I keep wishing they were high CRI. It’s the #1 spec I would change about them.
The flat, low-contrast look is a slight but constant irritant. Certainly, it’s better than having no light, but now it’s always on my mind. Before getting a first flashlight I had wondered how important CRI would be to me, and now I know…
The SP40 is the 5300K version. I wish I could have seen the 4000K in person, but in photos I thought I liked the 5300K better as a work light.
The E03H is sadly the cool white version (the Nichia version I really wanted was sold out and discontinued). The CCT is not mentioned but it is cooler than the 5300K.
I suggest to use lower CCT with high CRI for longer use at work. Light will be
more pleasant for eyes. Think it’s not hard change Led on SP40 once you have removed the silver ring.
Just use the right pliers or try to unscrew with a piece of rubber to avoid scratch the ring
My Wurkkos HD20 got a LH351D 5000k 90CRI flood LED and damn I’m really impressed by it! I Also got a Sofirn SC31 Pro (not a headlamp) with a SST40 5000k LED (not High CRI) but recently I started noticing it tint shifting on different power levels. I didn’t think I’d like the NW High CRI light as much but I really do! It’s not as powerful and bright as the SST40 but man I am impressed by the way I can see things with it around me!
