1. Design to meet the spectrum that water plants need for photosynthesis, effectively boost photosynthetic process, increase anthocyanidin and chlorophyll. 2. New invented high color rendering index (CRI), with color mixing technique and optical calculation, the LED bulb has over Ra95, very close to the natural light source. 3. High luminance, twice brighter than regular lights and only consumes half of electricity. 4. Alloy aluminum anodic cover and side cover, with heat sink design to lower down the temperature and prolong usage time. Only 4% luminous decay after using 6,000 hours. 5. Internal stabilizer and modular design, easy to repair and maintain. 6. Light angle 150°, uniform lighting with no light beam or Vignette.
