The 35w New Dawn Flood is a true 6500 kelvin LED light source, producing high light levels at the right wavelengths for powerful plant growth. The 35w flood has an 80° beam angle to flood light into larger enclosures. With its four separate LED bundles, the 35w model is different from the 10w & 25w New Dawn Spot. It has a reliable, quiet and highly efficient cooling fan to stop the LEDs getting too hot, greatly prolonging the working lifespan. Having a colour temperature of 6500k has been proven to promote the best vegetive growth for most plants, used because plant growth is induced by the bluer end of the natural light spectrum. Natural sunlight ranges from 2700 and 7000 Kelvin.
