 this  is  cool,  Rock On  
 i  have  4X2X2  planted  tank  running  with  7X36w  FL.  i  can  source  100x3W  Cree  XR-E  Q5  or  normal  3w  LED  with  lens.  but  the  most  confusing  part  for  me  is  the  numbers  of  drivers  to  run  this  setup.  i  am  not  good  with  all  current,watt,volt  &  AMP  but  i  am  good  with  soldering  &  DIY  things.
 
 my  requirement  is  to  have  minimum  numbers  of  driver  to  run  this  whole  setup.
 i  feel  lucky  to  have  experts  here  who  can  answer  this  &  help  me  to  complete  my  dream  project.  
 
 thanks,
 Bhumin

 Hello,
 I  would  like  to  mention  that  I  have  used  Red  and  Blue  indian  and  Chinese  LEDs  in  my  canopy  with  a  T5  Warm  day  light  Tube.  The  use  of  T5  supresses  the  unwanted  shades  and  is  useful  for  human  eye  to  enjoy  the  aquarium,  whereas  the  Red  and  Blue  light  constitute  the  PAR  (Photosynthetically  Active  Radiation)  light  for  the  plants.  I  am  using  about  30Watts  on  my  76.2X30.48X35  cm  Planted  tank  successfully  in  place  of  about  60Watts  (As  per  2.5  Watts  per  Gallon).  usually  it  is  said  that  Red  (2/3)  should  be  more  than  Blue  light  (1/3)  for  the  plants.  Light  is  light  whether  it  is  from  a  good  company  bulb  or  from  a  chinese  bulb  the  only  difference  is  in  their  specifications  and  durability  and  my  experience  is  that  there  are  some  durable  Chinese  bulbs  also.  By  using  Blue  and  Red  LEDs  we  can  cut  short  on  Yellow  and  Green  unwanted  spectrum  by  the  Plants  and  need  only  little  of  this  spectrum  to  nicely  visualise  the  aquarium.  I  will  post  my  snaps  of  light  arrangement  if  it  is  required.
 
 With  Regards,
 Ravinder  Singh

 Hello  radjanair,
 Thank  you  for  your  interest.  I  am  posting  some  snaps  for  your  and  others  perusal.  I  have  a  wooden  canopy  in  which  I  have  fixed  the  holders  to  hold  different  types  of  light  units.  The  blue  LED  lights  are  less  in  number  but  are  brighter  ones  and  they  are  kept  facing  horizontally  for  the  fact  that  the  blue  light  is  least  absorbed  and  can  penetrate  deeper  in  the  water  (even  after  reflection).  The  red  LED  units  are  more  in  number  and  of  less  power  (I  could  not  get  them  in  high  power  as  yet),  they  are  directionally  vertical  facing  downwards  (Red  spectrum  is  absorbed  more  in  air  and  in  water  and  converts  to  heat  to  some  extent  and  cannot  penetrate  deeper  ),  they  are  about  4”  apart  with  a  spread  of  about  45o.  There  is  one  T5  (2’)  Warm  day  light,  Chinese  tube  light  slightly  closer  to  water  surface.  The  purposes  of  T5  light  are  to  reduce  the  undesirable  colored  shades  in  the  aquarium  due  to  Blue  and  Red  LEDs  and  to  provide  some  of  least  required,  missing  spectrum  and  UV  to  the  plants.  The  presence  of  this  T5  light  keeps  the  Aquarium  and  the  plants  visually  more  enjoyable.  My  experiment  is  successful  and  my  plants  are  growing  vigorously  with  about  half  of  the  power  consumption.  You  can  see  some  snaps  on  the  link
 http://indianaquariumhobbyist.com/community/modules.php?name=Forums&file=viewtopic&t=25290&postdays=0&postorder=asc&start=30
 My  plants  are  in  the  pots  and  I  am  free  to  keep  them  slightly  closer  to  the  water  surface  or  deeper  as  required.

 Hello  radjanair,
 Kindly  see  the  link  below  and  the  link  in  the  last  post  for  your  answers
 
 http://indianaquariumhobbyist.com/community/modules.php?name=Forums&file=viewtopic&t=30185&postdays=0&postorder=asc&start=75
 
 I  have  three  Cryptocorenes  in  different  pots  and  one  Amazon  Sword  in  different  pot  which  is  growing  vigorously.
 I  am  also  feeding  the  fertilisers  prepared  at  home,  and  not  using  Co2.
 And  a  word  for  Bhumin,  this  setup  does  not  need  any  driver  circuit.  and  it  works  nicely.
 With  Regards,
 Ravinder  Singh
