It's here the Zebralight SC5C MK II H CRI

[gunga]

Hey great feedback guys. I'm definitely getting one. A bit annoying about the lack of free shipping but maybe I'll get it sooner. It's on backorder though.

The SC5 Mk2 weighs 18% less than the Mk1

thanks for all the pics... one of these is EasyWhite, who wants to guess

disclaimer, our brain will adapt to any single light source and auto white balance to it
these sorts of comparisons are interesting to me, but, any of these lights will do a good job if it does not have to compete with other ambient light

speaking of ambient light, my color temperature preference depends on the ambient light I am accustomed to at the time

if a location has 4000k ambient light, and I then use a 4000k LED light, it will not seem yellow
if a space is lit by a 5000k source, and I use the same 4000k LED light, it Will seem yellow
If I wake up in the dark of night, a 3000k LED will not seem yellow, but if I turn that light on in the middle of the day, it will be terribly yellow

don't let tint comparisons prevent you from enjoying a 4000k LED, just because we compared it to a 5000k and it looks more yellow
the brain adapts, especially when there is only one light source

Good point! In fact, I used 4000K WB since my bulbs were 4000K. But I don't think that matters since the overhead lights were turned off during shooting. I like shooting in the dark for that reason.

I know my brain doesn't adapt. After getting a new light, the minute I put a battery in and hit that switch, I either get really excited to totally ticked off losing the lotto again. It's immediately clear, every time. This nasty yellow doesn't need to be compared, but of course I did it because it really drives the point home.

People can make fun of white wall hunting all they want, but I don't care. It's the quickest and easiest way to find beam artifacts, beam type, and overall tint. I don't need to compare; if white paint shows up white, good. If not, what is it? Too green, yellow, magenta?

Focusing on just that part:

 

[wolfgaze]

Yeah, I'm looking forward to the 4500K SC5w II.

Mark, what's the story with that light you referenced? I don't know anything about it... Thanks

 

[snowlover91]

Mark, I think you either got a bad sample or just don't like this 4000k tint versus the pink of the Nichia. In my sample, each time I turn it it's a nice, pleasing tint. The best way to describe it is afternoon sunlight, that's exactly what it's like for me. After using it for awhile now it's definitely superior to my previous SC5w lights (2 of them!) and why I plan to get rid of them for this instead. Maybe you'll have better luck with the 4500k version.

It showed up for sale before going on their spreadsheet, I think. Too hard to keep track sometimes!

It's possible. But if you look at my cropped pic, I just don't see the pink (very little if any). Tintless, pure white on the 4500K Nichia. Totally superior. I like a nice afternoon sun for photography, but not to shine on everything all the time.

I hoped the CRI would overshine the warm 4000K like it did on my MD2, but clearly it did not. No CRI benefit + yellowish, so it's outta here.

Its not a totally fair comparison though to contrast a 4500k emitter with a 4000k one. A 4500k emitter will tend to be more white/cool as the "pure white" tint is around the 4500-5000k range with a good emitter. As you go higher you get the blue, ugly washed out 6500k spectrum and lower gives you a much warmer range. In your comparisons of the 4000k Nichia it had a TON of pink to the point the "white" on the toys looked like a light pink instead. The 4500k Nichia is definitely a pure white tint but the 4000k in this MK2 light is a nice golden sunlight color, at least in mine. Makes all my old 4500k emitters look too cool now (except my MK3 HI).

 

[markr6]

Yeah I get that, but call it what you will...9904.56K, it's still yellow/golden vs. white. That's what I'm after. I had it in my old SC5w OP, but didn't like the size/weight. I'll try again!

If they had this LED in a 5000k that would probably be perfect! The biggest thing I've noticed is even with one of my lights that I'd call close to a pure white, my MK3 Plus, it doesn't do as well with reds, browns and greenery as the warmer 4000k tint does. For me that's a huge benefit since most of my use is going to be outdoors and such. Plus, I don't have a single white wall in the house they're all cream colored :twothumbs

 

[markr6]

It's always good to err on the side of warm outdoors. Even when I sometimes complain about my H600w being a bit warm, it's always pleasing when running or backpacking. I never considered upgrading to the higher CRI versions because I don't want to gamble on something else.

there is no single color temperature that is pure white. Whiteness changes relative to ambient light adaptation. If I have been sitting in 5000k light, and turn them off to take a look at a 4000k light, it will look yellow. But If I have been sitting in 3000k light, and turn them off to take a look at a 4000k light it will look whiteleft 4000k N219b, right 4500k N219b

relative to 4000k, yes, 4500k looks more white (I would say greenish white)

but relative to 6000k, 4500k does not look pure white at all4000k, 4500k, 6000k

Please stick with the topic!
No place here for Nichia or AAA Lights! It's about Zebralight!

One more using Jonathan's setup. Sorry about the physical therapy exercise guy showing thru from the back...you're poor when you can't find any plain printer paper in the house! :laughing:

The L10 was only a little more intense in person, but exaggerated here. In real life, the outputs where very close and I would call it a fair comparison. Jon asked that I do this at 5000K, so here it is.

p.s. Something to keep in mind: I'm afraid to know how other monitors affect the outcome. I always knew this, but just got a stark reminder as I stood up and sat back down. At an angle from below, the contrast is super high on my monitor. From high, they all look about the same (white). From center, it looks life-like (slight pink...yellow...white). I'm not talking color balanced monitors here, just the way the contrast/saturation seems to change at angles. I have a middle-of-the-road Dell.

 

[jon_slider]

here btw is the same N219b as the other photos I posted above, and you can clearly see that it looks white, compared to a 3000k LED

thanks, by using 5000k white balance you have helped me see that the L10 is close to that CCT, and therefore looks more white than the warmer SC5c
but there is no denying the 4000k easywhite in the SC5c is more yellow than the 4000k N219b on the left

Quick question. Has anyone tried experimenting with the new ui yet?

 

[iamlucky13]

filtered PWM is something different for different purpose. also you seem to think the PWM controls the current, however PWM is the OUTPUT of the current-mode control circuit.

No, I'm talking about something a little more complex. PWM adjusted based on feedback upstream of a filtering capacitor can be used to control current.

Oh whoops, I mistakenly assumed this was going to be another Hi CRI model when I read your post earlier... Thanks for the link...

I sold my SC5w and had the SC5w Mk2 on my radar - but at this moment I'm not exactly feeling compelled to get the MK2... I may just spring for a new Spyderco instead (have to also sell another knife of mine though)...

Well it has pretty good cri, 83-85 and the 3 step so tint should be pretty good but a little bit of a lottery.

I haven't tried the new UI yet but plan to tonight when it gets dark, in about an hour
