For a hen to get the benefit of supplemental lighting you will need to use incandescent light bulbs that produce or give off ultraviolet light. A chicken has the ability to see objects in light spectrums that are invisible to us.

Chickens also have the ability to "SEE" light with organs other than their eyes. It is safe to say that a chicken sees a totally different world than you or I.
With the exception of Halogen light bulbs, any other light bulb other than an incandescent bulb and one tiny CLF spectrum is useless to stimulate a hen to lay. This is true regardless of what our politicians tells us.
