I have built both the pl520 and the pl515 and I can tell the difference. The pl 515 has a slight blue hue. I like the color of the pl515 better. My opinion.![]()

I can't help but wonder if the difference isn't more than 5nm. That amount of difference is so small that if you can see a difference it must be very slight. If they have the same power and divergence, I wonder if you could tell the difference if they were kept from you knowing beforehand which was which.
I know I'd like to know whether there is more of a shift and, if not, can one really tell the difference.
When I compared them I could differently tell the difference. But when I get a chance I'll try and get some half way decent beam shots.
Will be interesting to see the results. That said, your camera will probably have a hard time distinguishing between the two, more so than your eyes do. May need to edit the colours slightly in post to more closely resemble what you see. Still waiting on my 520 here, otherwise I'd compare too. :crackup: :crackup:
Good luck with your next builds, Bob. DTR makes it very easy to succeed.
