best light for increasing egg production? (we have real electricity to the coop!)

[mlcalmes]

Who told you this, nonsense? Yes, chickens have a Pineal gland that some call a third eye and it is photosensitive (as well as a photosensitive hypothalamus) and yes chickens can perceive some extended UV and IR range of light beyond what humans see... But that does not equate to fluorescent tubes being "a complete waste of both money and electricity" that is just silly nonsense... Fluorescent lights have been (and are still used) successfully in the commercial poultry business for decades... The Pineal gland (aka the third eye) that you touch upon that stimulates their egg laying is not tuned to the UV spectrum as you imply, instead orange/red wavelengths are what appear to best stimulate the Peneal gland and increase egg laying cycles...

If you are unaware red light in about the 630 nm wavelength is well in the 'visible' light range, near the middle in fact, it's far from UV...

If you read the above you will also see that other colors have their own benefits as well, but for egg laying the reds are what you desire...

In the end a custom tailored LED light setup that is tuned to the chickens red perception wavelengths is obviously optimal and best for egg laying stimulation, but that does not equate to other light sources like fluorescent being a waste of time as most are perfectly adequate, since they do put out a decent amount of light in the needed wavelengths...

Your typical fluorescent tube or compact tube will put out sufficient red wavelengths to stimulate egg production, as will most generic 'white' LEDs, using them is not a waste of money...

I personally provide supplemental light year round in my coop for at total of 16 hours/day with eight 9W 2700K CFL, my egg laying is steady all year with no seasonal changes due to light variations, but my coop is significantly larger than most...

None of these links work?
