look for a more yellow light. blue and white are reflected by the egg shell so the color is very important.(I think Bama learned that from me--I started posting that a couple of years ago).
There was another poultry study about it.
Darn. Just got a Cree 600 lumen led and it's definitely a bright bluish-white light. I tried it out and spot check candled a few and wasn't able to see much more than I could with my cheap-o little 8 lumen led
