Guys, wait for 351D tests for final decision.
I own a 351D light (rated 90+ CRI fwiw), and several Nichia 219B's. I've compared the 4000K versions of each, side by side. The Nichia has slightly richer, more vibrant colors.
Obviously, there are other factors like efficiency, output, beam, etc..., so it would be difficult to call one or the other "better", but the Nichia shows colors better to my eye.
I have no dog in this fight but a warm metal needs a warm emitter. Loving this 90CRI 3000K XPG2 in my WM61LLLL it is very pleasant. I would definitely be fine with a rotary with this emitter.
It sounds like the decision was done on how much BeCus are made. Therefore how much of this babies will be made. I am sooooooo curiousThe pre-order for the run of Beryllium Copper Rotary flashlights has ended. We will produce a few extra. After the pre-orders have shipped around the end of the year, we will offer any remaining lights at a base price of $1250.
