Best Praise
+19 pts“Not much of a story but one time I was walking with a buddy by a golf course that was part of a park. It was not gated at all so we assumed it was public and ok walk through to get to the other side. While making our way across we get absolutely lit up from what we assumed was a security guard. We couldn’t see anything at all and covered our faces, wincing. They didn’t say anything. Then I remembered something…I had my D4SV2 with W2’s in my pocket! I grabbed it and returned fire with some turbo. They were bewildered from being completely illuminated and utterly exposed and they turned away immediately. We turned our lights off and walked a different way out and they didn’t follow. It felt so empowering to have that sort of control of a situation when they probably felt the same way. There’s always a bigger fish in the sea and that night it was me.”

+2 pts“I’m solidly in the 4000-4500K camp. I don’t want a blue or red tint. Occasionally 5000K is okay but somehow starts to look a tad blue sometimes and a little lower is on the safe side. I can also tolerate a little more on the + side duv than I can on the negative. It gets rosy quickly for my eyes. I have a D4SV2 that I mistakenly had the 4500K 519a’s dedomed and now is about 3300K and I’m thinking of getting rid of it and ordering another one. I feel that 4000K-5000K as close to 0.0 duv is the perfect match for indoor or outdoor use for what I prefer.”
