The 25w New Dawn Spot is a true 6500 kelvin LED light source, producing high light levels at the right wavelengths for powerful plant growth. The 25w spot is for medium size planted set ups and has a 25° beam angle. Both the 10w and 25w models utilize a, tried and tested, heavy duty aluminium heatsink casing, allowing heat to be efficiently dispersed from your LEDs, prolonging their life. 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. For the volume of light being produced these are still very low wattage saving you money on running costs.
