Understanding the color spectrum given off by a light source will assist producers in selecting a light bulb which can deliver the proper amounts of red, green and blue light. Light bulb color can be expressed in degrees Kelvin (K) and color rendering index(CRI).

However, neither of these measurements expresses the spectral peak intensity in the red, green, and blue spectra that are important for poultry growth and production.
What kind of color is good for chickens?

Chickens have four cone cells typical of birds: the UV-cone (ultraviolet, peak sensitivity = 420 nm), S-cone (small wavelength, peak sensitivity = 470 nm), M-cone (medium wavelength, peak sensitivity = 540 nm), and the L-cone (large wavelength, peak sensitivity = 600 nm) .

Hontech-Wins Poutry Lighting; White Color:
The “white” visible light launched naturally by both sun and artificial light sources are actually comprised of numerous colors, actually composed of a range of colors, red, green and blue color. It is available from 2700K to 6500K. According to the research , pullets may be reared with warm or cool lights, but laying hens should have
lights with a sufficient red spectrum (2700K–3000K)

Hontech-Wins Chicken Lighting; Red Color:
In poultry, red light is vital for stimulating sexual maturity and egg production. Birds exposed to red light versus blue, green or white light consistently have higher egg production than the other color groups. Red light is able to to 38 eggs per hen, while potentially decreasing food consumption by up to 20%.

Hontech-Wins Agriculture Lighting; Green Light:
Green light, significantly increases growth rate at an early age by enhancing proliferation of skeletal muscle satellite cells.

Hontech-Wins Dimmable LED Lighting; Blue Light:
Blue light increases growth at a later age by elevating plasma androgens and keeps birds calmer which improves feed conversion.

Hontech-Wins LED chicken light; Blue and Green light:
Together, green and blue light promote myofiber growth due to more effective stimulation of testosterone secretion and improved feed conversion.
