? 【The Safest CMH Bulbs】The bulbs are inspected and licensed by United States Federal Nuclear Regulatory Commission (NRC) that regulates Krypton-85, a nuclear radiational material incorporated in most CMH bulbs. Therefore, they are safe to humans, animals, plants and environment. The outside glass sleeve of tube will contain all broken components for extra protections.
? 【Designed for Horticulture Industry】The CMH bulbs are designed and manufactured for horticulture industry to generate maximum yields. The spectrum of 4000K horticulture CMH with a bell shape is very similar to natural Sun light at noon. This continuous Sun-like light help plants grow perfectly in vegetative stages for strong and healthy stems and leaves with a reduced grow cycle.
? 【Long Life Time】The light of 4000K horticulture CMH decays much slower than traditional high pressure sodium bulbs (HPS) and metal halides (MH). They can maintain 90% of their initial lumen output at 8,000 hours operation time.
? 【Outstanding Efficacy and Par Value】The bulb has Photosynthetic Photon Flux (PPF or PAR Value) of 540 uMol/s, consumes 315 Watt electrical power with 33,000 Lumen light output. The light efficacy is 105 Lumen/Watt.
? 【Superior Color Rendering Index】The CMH has a very superior color rendering index (CRI) of 96. The CRI is a measure of a light source's ability to show object colors naturally. All growing plants under the CMH lights will show their TRUE colors.
