Akos, wow! Thank you for sharing these facts in regard to how much LED lights lack compared to tungsten. I was going to purchase LED lights; instead I am going to purchase tungsten.

Additionally, I agree with you, the next time they (i.e., NFS) test new LED lights they should include a REAL scientist (3rd party - unbiased). A real physicists would be ideal, one who's specialty is light. They could contact a local college or university and ask the professor to be on the next LED light review. In fact, ALL reviews should include someone who knows what their talking about - henceforth, when making a proper review, then they should back the claim up scientifically (note: Subjective opinions mean nothing - all reviews shall remain objective!).

In closing, these LED light reviews are of no value if they do not scientifically report the correct data. I am hopeful that "No Film School" will kick it up a notch! :)
