L1P High CRI(93) Seoul P4 高显色指数（93）汉城P4

CPF看到一帖，貌似很有趣，遂分享。

"I have been noticing the tint more and more on my LED lights lately,and had tried a number of different tint bins from different manufacturers,in an attempt to find something neutral,but with decent color rendition.Then when McGizmo started the High CRI and Sundrop threads it clinched the deal.I've missed a couple of group buys(work) for the Nichia's Mcgizmo has so I ordered some of the High CRI Seoul emitters and have put them in a number of hosts to try out,one is a Fenix L1P modded with the RV7 3 level driver and High CRI LED.I wanted to share my initial impressions.

First,the tint I got were a little warmer than I had originally wanted,Natural White SRO,but the color rendition is awesome.The tint seems to be a higher than a standard 75w incandescent,but still a little warm.It is hard to describe how much of a difference there is between these and the lower CRI emitters.Reds and skin tones are the most apparent difference,with green close behind.There is no tint shift at all when switching from a conventional light source to these LED's.

The output is lower than the latest flux bins in pure white,60-70 lumens at 350ma for the bin I got(S2),still decent though.

I am very pleased with the outcome,though I would prefer a higher color temp,STO would be great.

Be advised,it becomes harder to accept the lower CRI of other emitters the longer you use these,though output does trump CRI at times.As McGizmo says,sometimes it is better to see something well than barely or not at all with high CRI.

Mandatory beamshots...though these don't quite relate to what I am seeing.Exposure adjusted on some to compensate brightness.”

鸟语水平有限，我只能大概翻译一下，接触LED不久，错误处请不吝指正。

“……我想分享自己的初期印象。

首先，色温比我喜欢的要低一点，自然白SRO，但显色性非常好。色温比75W白炽灯要高些，但仍然有点低，这些发光体与普通发光体显色性的区别很难形容，对红色和肤色的表现是最显著的区别，然后是绿色。从普通光源转换到这些LED时物体色调完全没有变化。

    输出能力比最新的纯白要弱，我拿到的S2在350mA时60-70流明，基本还可以。

    虽然我更喜欢更高色温的，如STO，但这次的结果仍令我非常满意。

即便是亮度要差些，使用这些LED越久，越难接受普通LED的显色性。像McGizmo说的，sometimes it is better to see something well than barely or not at all with high CRI.（不会翻译）。
……”

照片曝光根据亮度补偿，发几个有代表性的。

我要沙发。

另外参考：

CRI是用作检测光源在投射于各种对象后将色彩重现的能力，以区别不同光源发放相同色光的特征。天然阳光的CRI/Ra为100，被定为最佳色彩显现指数，通常CRI(Ra=80)已属于较高指数。

还有一点SSC的资料http://shoudian.org/viewthread.php?tid=49951&highlight=ssc，我是不太懂。

这个高显色性led是什么来头呢？貌似非常适合EDC。

和5C还是差些～依然免疫～哈哈

5C那么牛？！
ICR多少呢？

翻译的不错，LZ辛苦了:handshake

看顯色性還是直接照色版上比較直觀

这个就是暖白SSC P4，挺早就有卖的，很低调，照片的白平衡不好，实际应该更黄。

P7也有暖白bin.光效偏低，但是总体表现很令人期待。

总之色彩还原要好，这样才有助于夜晚在陌生环境下使用。在城市中熟悉环境下，色温高点问题不大，在野外就得当心了

色彩还原很强，虽然不如白光亮，但估计远射也有优势，不会像白光一样被光柱挡住了视线，不知5C表现和这个有什么区别？

以我为荣

q25c?

恩，查了下资料，Q2 5C 显色指数75，和这个93不是一个数量级的。

还看到一种CRI 98的，显微镜用LED。
