D4v2 519a 5000k LEFT E30 Pro Rovyvon SST40 7000K~ RIGHT I think both the temperatures and CRI contribute to this difference.
I was testing multiple flashlights and happened to shine them at my mahogny guitar. And the 519a 5000k just made me smile.
The 7000k sst40 (E30 PRO) is on the right and just looks horrible to me. Very unnatural. It has its purposes but I'm personally not a fan. Also the tail switch gets jammed easily, right out of the box. Returning for sure.
