 Hi  All,
 
 Last  month  did  a  trial  led  fixture(below  is  the  link)  to  test  whether  plants  do  well  or  not,  and  found  plants  do  really  well  with  the  led  so  planned  to  upgrade  from  the  trial  led  fixture  with  proper  heatsink.
 
 http://indianaquariumhobbyist.com/community/modules.php?name=Forums&file=viewtopic&t=38122
 
 Below  is  the  pic  at  the  time  of  installing  the  trial  led
 
 
 
 this  is  after  26days  running  in  led
 
 
 
 yesterday  did  a  major  trim  and  removed  some  plants
 
 
 
 Below  is  the  heat  sink  which  i  cut  into  4  pieces  and  made  like  fixture  structure
 
 
 
 Backside  of  heat  sink
 
 
 
 Using  screw  and  nut  fasten  all  the  heat  sink
 
 
 
 Trial  led  fixture  and  the  new  at  the  time  of  making
 
 
 
 Fixed  14  nos  10Wled(6500k)  to  the  heatsink  with  adhesive  thermal  paste
 
 
 
 fixed  2  nos  1w  high  power  red  led  and  6  nos  1w  high  power  blue  led
 
 
 
 soldered  the  leds  and  added  a  potentiometer  for  dimming  the  leds
 
 
 
 bought  2  nos  acrylic  sheet  to  cover  front  and  back  and  added  two  cpu  fans  in  back  cover  for  cooling.  
 
 
 
 fixed  front  cover  acrylic  sheet  with  the  fixture
 
 
 
 fixed  back  cover  with  heatsink  and  connected  the  fans  with  the  wire
 
 
 
 gave  connection  to  driver  for  red  and  blue  led
 
 
 
 for  cool  white  led  also  gave  connection  to  driver
 
 
 
 Testing  the  potentiometer  to  check  whether  it's  dimming  i  connected  only  6  leds  to  the  potentiometer  in  below  you  can  see  6  leds  gone  to  low  intensity
 
 
 
 tomorrow  will  install  this  fixture  to  my  tank  once  done  will  post  a  pic.

 what  are  the  specification  of  the  SMPS  and  which  wires  are  you  connecting
                 

 
 I  ordered  my  led  drivers  from  Aliexpress  below  is  the  link,  but  will  take  25-35  days  to  come  Rolling Eyes  
 
 http://www.aliexpress.com/item/S-360-fonte-dc-12v-30a-360w-24v-15a-fuente-de-alimentacion-switching-power-source-supply/32228792931.html
 
 http://www.aliexpress.com/item/15w-MD-15-ac-dc-220v-3-3v-4A-5v-3A-12v-24v-mini-slim-switching/32260191630.html
 
 above  site  in  top  right  you  need  to  change  the  flag  to  India  and  currency  to  inr
 
 One  driver  is  3.3v  with  4A  which  i'm  using  for  red  and  blue  and  another  one  is  12v  29A  driver  which  I'm  using  for  cool  white  leds.
 
 You  need  to  order  driver  for  the  led  you  choose,  the  led  which  i  use  is  
 
 12  nos  10w  led  with  12v  1A  cool  white(6500k)
 2nos  10w  led  with  12v  1A  cold  white(10000k)
 6  nos  1w  hi  power  blue  led  with  450nm  3.3v  <  .05A
 2  nos  1w  high  power  red  led  with  650nm
 
 So  driver  requires  for  my  14  nos  10w  led  is  12v  14A,  so  i  ordered  for  12v  29A  driver  so  in  future  i  can  add  extra  15  more  10w  1A  leds  with  my  driver.
 And  for  red  and  blue  is  3.3v  driver  which  i  ordered  3.3v  4A  because  red  and  blue  led  will  take  0.35A  only.  so  i  can  add  around  12-15  leds  with  the  driver  i  bought.
 
 Below  is  from  ebay
 
 http://www.ebay.in/itm/12V-10Amp-120W-DC-Power-Supply-Driver-for-CCTV-and-LED-Strip-light-Lamp-Wrty-/321745421772?pt=LH_DefaultDomain_203&hash=item4ae98585cc
 
 i  didn't  find  driver  with  above  15A  so  i  ordered  from  aliexpress  and  it's  damn  cheap  too.
 
 Yes  i  used  SMPS  for  my  trial  fixture  now  also  using  my  smps  only  because  still  my  12v  driver  didn't  come  Sad,  the  advantage  you  got  in  smps  is  you  have  3.3v,  5v  and  12v  so  no  need  to  buy  extra  driver  for  white  and  red  led  the  one  which  i  use  has  below  power
 
 
 
 It  supports  24A  in  12v  so  i  can  add  24  leds  and  in  3.3  it  supports  28A  where  i  can  add  a  roll  of  1w  led  itself   Chuckle  
 
 once  you  remove  smps  you  need  to  connect  green  and  black  then  only  your  smps  will  start  when  you  power  on,  And  in  all  smps  yellow  wire  is  12v,  red  is  5v  and  orange  is  3.3  v,  join  all  the  yellow  wire  together  and  red  wire  together  and  orange  wire  together  please  note  in  old  smps  you  will  see  brown  wire  which  you  need  to  join  with  orange  wire  or  else  there  will  be  some  power  loss  in  3.3  v,  below  is  the  picture  of  my  smps,  you  can  see  i  have  taped  all  yellow  together.  and  i  received  my  3.3v  driver  which  you  can  see  below,  i  bought  this  drivers  to  fix  it  in  my  wall  where  this  smps  I'm  not  able  to  fix  and  in  future  also  I'm  planning  to  make  a  5  feet  tank  so  i  require  more  leds  so  buying  this  this  driver  i  can  easily  increase  the  nos  of  leds.
 
 
 
 If  you  really  wanna  do  in  a  professional  way  go  through  the  below  links
 
 http://www.instructables.com/id/ATX--%3E-Lab-Bench-Power-Supply-Conversion/?ALLSTEPS

 Awesome  project!
 
 I  wish  to  do  something  similar  but  smaller.  I  was  wondering  if  you  could  help  me  decide  on  a  power  supply.  I  would  be  needing  6x10W  whites,  1x1W  red  and  2x1W  blue.  This  Link  you  provided  is  a  bit  costly  for  my  project.  I  can  get  an  SMPS,  however  I  am  not  sure  if  I  can  get  my  required  output  from  the  SMPS.  I  have  estimated  my  requirement  at  7A.  Not  being  from  a  pure  electronics  background,  I  feel  a  bit  overwhelmed  with  the  power  supply.  Searching  online  I  could  find  this  12V  2A  power  supply  however  it  does  not  specify  if  it  will  run  10W  LEDs.  If  it  does,  then  I  plan  to  use  3x2A  power  supplies  for  the  white  LEDs,  and  1x1A  for  the  other  3  leds(which  are  rated  at  300mA  each).  What  do  you  suggest?

 Hi,
 
 check  the  below  link  
 
 http://www.ebay.in/itm/12V-10Amp-120W-DC-Power-Supply-Driver-for-CCTV-and-LED-Strip-light-Lamp-Wrty-/321745421772?pt=LH_DefaultDomain_203&hash=item4ae98585cc

 And  for  1w  led  it  will  be  3.3v  not  12v  so  you  need  get  3.3v  driver.
