NEEWER

4.0 / 5.0

NEEWER LED-NL660 というものをタイムセールで買ってみたので ColorMunki Photo + Argyll CMS で測定してみた。

 

WHITE と YELLOW というつまみがあり、2種類のLEDの光量が変更できるようになっている。色温度の調整はこれを微妙に動かして行う。

WHITE 全部

スペック上は5600Kまでと書いてあるが 5500K の LED っぽい。

3100Kぐらいが下限

最も明るいが4200Kぐらいの中途半端な色温度になる。

5000K

5000K 程度にあわせたとき。(WHITE 全部+YELLOWが左水平とちょっとぐらい)

Ra は全ての指定色でかなり高い値が出てる。R12(青)もそこそこ高い値が出ていて良い。
