you might want to buy an Opple Light Master.. it really helped me choose the LED lights in my house…
here is a discussion thread about the Opple
What I found is that the 3000k Photo Grade lights from Waveform have very nice tint, and less flicker than the cheaper bulbs I find at Home Depot.
I like being able to compare flicker and Tint, using a meter, instead of just my eyes.
