More features about King Series KS400 :

       ·Perfect Mix of 3 Watt and 5 Watt Diodes, improving 20% PAR than the market’s similar light

       ·aluminum heat-conducting and aluminum shell for better heat dissipation

       ·4 channel dimmable

       ·3 kinds mode including 24 ‘mother earth’ Timing Function,Automatic,  mode,manual mode 

       ·Light transmittance of the lens reached 93%

Advantage:
 

1.Original import chip guarantee that lifespan and PAR.

2. Special lenses design, magnify that chip effect, 60 90 120 degree lenses, providing more footprint than HPS light.

3. Fully customizable spectrum, 12 band spectrum for customer choice.

   (Red are mainly 630nm 660nm, 660nm spectrum is better than 630nm spectrum for plant flowering.

4. Take Double roller and low noise, lower noise, special appearance deisgn with certain radian.

5. Auminum heat dissipation , lower that temperature, extend that lifespan,  reaching that UL standard.

6.24 Stage ‘mother earth’ Timing Function allows user to mimic the great outdoors like never before seen in indoor growing, slowly waking your
