 WPG  is  a  beginer  rule.  and  lumens  per  watt  is  also  not  needed.  the  most  important  thing  is  the  intensity  and  PAR....  that  makes  big  difference.

 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.

 @abhi_123  -  I  kinda  agree  with  you.  If  the  Bridgelux  LED  is  able  to  do  the  job  at  $100  cheaper  ,  there  is  absolutely  no  point  in  sticking  to  CREE.  I  can  vouch  for  this.  I  bought  a  Hagen  2x24W  T5  GloLite  fixture  sometime  back  but  I  refused  to  go  with  the  Hagen  tubes.  Just  went  and  bought  the  stuff  from  Bajaj  and  they  work  absolutely  fine
 
 I  don't  see  any  difference  at  all  -  both  CREE  and  Bridgelux  are  US  companies  and  both  are  over  20  years  old.
 
 I  have  a  question  for  you  -  the  stuff  which  you  are  getting  from  China  -  is  the  supplier  some  kind  of  authorised  distributor  or  OEM  manufacturer  for  Bridgelux  or  is  he  an  online  seller  ?  I  am  curious  to  know  how  will  you  know  whether  the  stuff  is  genuine  ?  Have  you  purchased  from  them  before  ?

 He  is  wholesaler  &  deals  only  in  meanwell  drivers  &  bridgelux  leds  &  to  be  frank  even  american  companies  are  dealing  with  chinese  leds.  I  haven't  purchased  anything  from  him  yet  as  he  don't  entertain  retail  orders.  I   am  ordering  him  LEDS  &  Drivers  this  week  if  you  are  interested  than  let  me  know.  Contact  is  Genuine  has  been  given  by  a  senior  Reef  Hobbyist  of  Reef  Central.

 I  know  we  have  gone  off  topic  a  bit  here.  Smile  
 
 To  answer  and  end  it,  well  when  it  works  well  even  for  5yrs  I  wouldnt  want  to  spend  more  anyway,  thats  why  -buy  the  most  modern  stuff  thats  on  shelf,  and  CREE  has  them  now.
 Fluorescent(technology)  have  been  in  hobby  for  atleast  10yrs?  so  expecting  LEDs  to  be  in  market  for  5yrs  might  be  a  safe  enough  expectation  for  now...more  over  any  new  tech  gets  affordablly  cheaper  for  hobby  only  in  2/3  years,  thats  as  I  ve  seen   the  trend.

 I  am  not  complaining  about  the  money  involved  in  this  hobby  nor  m  going  to  use  led  just  to  save  some  bucks  but  the  thing  is  that  i  dont  prefer  or  use  anything  just  because  everyone  is  using  or  recommending.  I  recently  purchased  a  dosing  pump  from  marine  magic  just  for  half  the  price  of  Highly  Rated  Bubble  Magus  &  the  performance  of  this  pump  is  way  too  good  when  you  compare  it  &  it  is  not  my  personal  view  you  can  google  for  it  &  find  thousands  of  hobbyist  satisfied  with  its  performance  but  that  doesn't  means  no  one  is  buying  Bubble  Magus  or  any  other  dosing  pumps.  same  is  applied  here  too  its  the  wish  of  buyer  what  he  wants  to  have  &  what  he  don't.  Marketing  Stunt  doesn't  make  any  product  special  &  similarly  lack  of  marketing  doesn't  make  quality  poor.

 The  topic  discussion  is  going  in  a  wrong  direction.  Lets  not  deviate  from  the  topic.  Our  friends  wants  to  know  if  any  body  off  us  have  used  Cree  led  setup.  If  yes,  please  help  him  in  that  rather  than  going  off  topic..!!

 @Shelly..thanks.  All  I  want  to  know  is  has  anyone  used  the  CREE  LED  setup  ?  How  many  Cool  White  3W  LEDs  would  one  need  for  a  60g  setup  ?  Should  I  look  at  lumens/watt  or  watts/gallon  as  the  factor  to  determine  the  number  of  LEDs  ?

 For  that  size  tank,  i  would  suggest  you  get  about  24  and  use  80*  optics.  Since  its  a  planted  tank,  just  make  sure  you  space  them  to  get  good  coverage  over  the  entire  setup...
 
 If  its  less  you  can  always  add  a  few  more..
