 Dear  Friend,
 My  next  ambitious  DIY  project!!!  -  DIY  LED  Lighting  for  the  Aquariums  !!!
 
 Started  with  many  many  researches  on  LEDs..  and  found  that  MaxSpect  Light  (one  of  the  more  used  LED  fixtures  in  US)  used  Edision  LEDs  (Instead  of  CREE)...  so  sourced  the  LED's  directly  from  Taiwan  for  test  phase...
 
 Then,  using  the  Experts  on  ReefCentral...  started  a  build  on  the  Driver  for  the  LED  using  an  IC..  invested  some  thousands  into  it  and  later  found  that  the  Dimming  of  the  LEds  was  not  working..  so  had  to  re-work  on  another  IC...  and  just  yesterday  completed  that  PCB  and  tested  the  LEDs  with  the  new  IC...  and  found  that  everything  worked  wonderfully..   Cheering  
 
 and  i  have  lights  dimming  ON  and  OFF  at  will!!!  so  that  i  can  get  Whatever  color  temperature  that  i  want  ranging  from  6500K  to  pure  Actinics!!!...
 
 the  model:
 
 1.  84  LEDS  ...  42  Cool  Whites,  and  42  Royal  blues
 2.  Arranged  in  a  grid  of  48"  X  18"
 3.  60  Degree  optics  on  all  LEDs.  Can  eliminate  optics  if  you  are  going  to  keep  the  LEDS  closer  to  your  tank.  But  i  wanted  them  @  2  feet  from  the  tank  so  the  Optics.
 4.  14  Drivers...  to  drive  these  LEDS
 5.  2  Dimming  signals  to  Dim  the  whites  and  Blues  separately.  Can  create  night  effect,  deep  sea  effect..  sunrise-sunset  effect..  unbelievable  the  options  are!!!!
 
 
 All  LEDS  are  fixed  on  the  Heat  Sinks..  wirings  are  done...  testing  is  ON...
 
 Will  post  images  soon....

 Hey  Pk.
 
 Super  go  on  the  project,  all  the  very  best.  I  am  thinking  on  something  similar  for  my  nano  project  but  using  simple  LED's,  nothing  jazy  this  time.
 
 Hey  do  post  some  pics  of  the  DIY,  also  how  many  Watts  are  these  LED's
 
 Warm  Regards

 thanks  guys..  
 
 @beta,  drop  in  anytime..  it  is  running  now!!!  and  when  dimming  it  is  like  a  two  color  disco  light!!!  ha  ha  ha  ...
 
 @nash,  they  are  3W  LEDs.  You  will  not  have  enough  power  if  you  use  the  regular  LED  or  even  the  1W  Leds.  We  dont  get  proper  drivers  to  drive  them.
 
 Working  on  the  camera!!!  -  will  post  pics  soon

 While  you  are  sitting  idle  testing  rig  up  a  couple  for  my  15  x  10  x  12  tanks.  6500  K  will  do.
 Put  as  much  light  as  you  want.  Very Happy

 madan...  3W  is  far  more  than  enough..  and  with  optics  it  can  reach  far  far  depths  with  high  intensity...  i  am  using  60  degrees  and  i  the  light  reaches  the  roof  !!!!  5W  is  too  much  concentrated  power  in  one  place..  thats  why  many  dont  use  the  5,10  or  20W  LEDS...
 
 Whola!!!  15X10X12!!!!  what  is  the  depth  then?  r  u  seriously  serious  abt  it?  then  you  need  8  degree  optics  to  reach  that  depth.  if  you  are  setting  something  for  that  tank  and  if  marine,  then  you  can  buy  a  plot  in  bengalure  for  the  cost  into  LEDs!!!   Chuckle  ha  ha  ha  
 
 @prasad:  soon  pics  will  be  up...  still  working  with  my  camera.
