Well perhaps you can send a message to Dan and he can provide you with some?
The problem with “data” though is that on a technical subject like this one the best data also requires training and experience to understand and interpret properly. This isn’t just “which one has the most lumens”, there’s a lot to it.
Understanding the physics of light, the physiology and mechanics of human vision etc are all a part of it. So just looking at some specs on the internet probably isn’t going to allow someone without training to make the best decision. There are experts for a reason, the whole point is that they understand the subject better than you. Which is why I’m perfectly happy taking advice from one.
