 @Saikumar  -  yes  ,  one  of  these  guys.  Farnell  has  prices  in  India  currency  and  supplies  of  one  piece  also.
 
 @Abhi_123  -  Bridgelux  somehow  does  not  appear  to  have  too  much  of  traction  amongst  hobbyists.  I  cannot  be  sure  ,  perhaps  it  has  something  to  do  with  quality/output/PAR  values  etc.  Nevertheless  ,  it  is  worth  exploring.
 
 The  Meanwell  driver  is  available  on  Farnell.  But  the  price  is  exactly  3  times  of  the  price  elsewhere.

 I  am  following   lots  of  threads  on  reef  central  &  other  international  forum  on  LED  for  a  quite  some  time  now.  What  i  have  learned  from  the  experiences  of  fellow  hobbyist  is  that  your  corals  or  plants  are  still  not  that  smart  to  recognize  which  make  leds  are  you  using.  Majority  of  them  Agrees  that  Cree's  LEDS  are  over  priced  &  much  hyped  than  actually  what  their  performance.  Overall  the  basic  difference  comes  only  after  30000  hours  of  usage  &  LEDS  are  still  very  new  to  market  so  i  dont  think  any1  has  still  used  them  for  such  a  long  period  before  conducting  any  conclusion.

 @  abhi  -  well  said,  
    some  times  just  because  some  thing  is  in  demand,  does'nt  mean  its  the  best..
 Its  somthing  like  sheep  follow  sheep  case..  where  one  says  its  good  and  others  follow  blindly.

 Looks  good  but  are  expensive.  If  you  are  seriously  considering  Cree  than  go  for  www.rapidled.com
 
 PS  :  -  I  am  not  associated  with  Rapidled.com  &  i  dont  have  any  financial  interest  with  them.

 Rapidled  charges  37$  as  shipping  charge.  So  consider  this  price  too  if  you  have  plan  to  order  from  here.

 I  know  that  flood  lights  are  cheap  chineese.  but  all  the  big  manufactures  have  tags  made  in  china.  well  just  type  led  flood  lights  planted  tank  and  see  the  results.  there  are  also  these  GU10  led  bulbs  that  has  been  used  by  many  in  reef  tanks  with  much  greater  success.  the  lenses  just  spread  the  light  nothing  else.  im  using  them  on  my  marine  tank  too  and  i  can  see  the  difference.  here  is  a  thread  on  GU10  bulbs  used  for  reef  :
   http://www.nano-reef.com/forums/index.php?showtopic=267432
 
 If  you  see  then  all  the  CHIP  LEDs  are  very  intense  and  powerful.  the  thread  above  also  shows  the  par  reading.   they  are  suing  3watt  bulbs  (each  bulb  has  3  1w  leds)   have  a  look.
 
 Look  at  the  make  of  big  brands  that  make  aquarium  led  lights.  all  use  CHIP  leds....   well  soon  ill  be  making  a  good  video  on  it,  and  posting  it.

 2.  High  Lumens/watt  (  NOT  at  low  currents,  BUT  at  maximum  current)
 
 Check  the  same  for  bridgelux  and  we  can  compare.

 What  i  meant  was  that  ALL  CHIP  LEDs  ARE  HIGH  POWER.  THE  LED  IN  FLOOD  LIGHT  AND  GU10  ARE  BOTH  CHIP  LED.   well  the  best  way  to  check  KELVIN  is  click  a  photo  and  see  the  RAYS.  if  they  look  a  bit  blue,  its  8000k  or  above  and  if  pure  white  6500k.  i  forgot  to  mention,  that  in  my  earlier  setups  when  i  use  to  use  t5ho,  i  used  1  blue  for  3  whites  for  better  penetration  and  darker  green.  Not  tried  on  floods  though.

 My  tanks  are  all  15"  height  so  10w  floods  are  enough.  if  higher,  i  would  use  20s  or  30s  or  50s.

 I  know  that  flood  lights  are  cheap  chineese.  but  all  the  big  manufactures  have  tags  made  in  china.  well  just  type  led  flood  lights  planted  tank  and  see  the  results.  there  are  also  these  GU10  led  bulbs  that  has  been  used  by  many  in  reef  tanks  with  much  greater  success.  the  lenses  just  spread  the  light  nothing  else.  im  using  them  on  my  marine  tank  too  and  i  can  see  the  difference.  here  is  a  thread  on  GU10  bulbs  used  for  reef  :
   http://www.nano-reef.com/forums/index.php?showtopic=267432
 
 If  you  see  then  all  the  CHIP  LEDs  are  very  intense  and  powerful.  the  thread  above  also  shows  the  par  reading.   they  are  suing  3watt  bulbs  (each  bulb  has  3  1w  leds)   have  a  look.
 
 Look  at  the  make  of  big  brands  that  make  aquarium  led  lights.  all  use  CHIP  leds....   well  soon  ill  be  making  a  good  video  on  it,  and  posting  it.
                 
 When  you  say  3W  are  good,  it  means  Floodlights  are  inferior  right?  Wink                

 
 It  doesnt  matter  for  me  whether  i  go  for  bridgelux  or  cree  or  any  other  LEDs  when  i  can  see  growth  in  my  tank.  i  was  just  saying  instead  of  shouting  for  Cree  LEDs  we  should  not  under  estimate  other  makes  too.  may  be  with  the  time  you  can  see  some  other  brand  over  take  Cree  in  near  future.  you  can  find  many  criticizing  cree  as  well  as  praising  them  so  it  is  not  compulsory  that  PAR  Value  &  other  technical  stuff  will  make  any  difference.  We  are  dealing  with  live  stock  here  &  we  humans  cant  compete  with  nature  in  any  sense  to  provide  the  same  what  nature  is  providing  us  so  regular  experimenting  is  essential  to  explore  new  development  instead  of  blind  following  the  older  ones.

 Just  for  Comparison  
 
 A  Bridgelux  48  x  3w  fixture  with  mean  well  driver  &  80  degree  optics  will  cost  u  178usd.  The  same  fixture  with  Cree  led  will  cost  u  roughly  278  usd.  Drivers  are  meanwell  LPF-60D-48.  Both  fixture  are  dimmable.
 
 If  i  am  able  to  save  100  usd  just  for  a  sake  that  i  m  not  branded  fellow  i  find  its  a  clever  deal  when  i  am  assuming  that  all  leds  will  last  for  only  4-5  years  with  me  after  that  i  have  to  go  for  a  new  fixture.
