 Thought  to  start  a  new  thread  just  in  case  someone  wants  to  know  about  LED  floodlights.
 
 My  tank  specs  are  4(length)x2(height)x1.5(depth).  I  have  2x50W  LED  floodlights  in  my  tank.
 If  you  are  wondering  how  it  looks  like,  here  is  a  pic  of  the  light.
 LED  50W-  Click  here
 Pros:  
 
 1.  I  like  the  way  the  unit  is  setup.  Lights,reflector  all  in  same  pack.  No  separate  chokes  and  stuff.
 
 2.  Low  power  consumption  per  unit.
 
 3.  Good  color.(pure  white)
 
 4.  Cheaper  than  T5  HO  if  you  go  for  the  normal  floodlights.
 
 5.  Shimmering  -  for  those  who  like  it.Smile.  See  point  6  in  Cons.
 
 Cons:
 
 1.  LED  floodlights  available  in  India  are  not  the  best  LEDS  in  terms  of  lumens/watt.  So  if  you  saw  in  an  american  thread  that  LED's  are  perfect  and  that  10W=  50W  halogen,  its  only  for  those  expensive  LED's  which  they  have  access  to.  Might  be  you  can  find  those  in  India  but  are  5  digit  in  cost.(At  least  upper  4  digit  is  what  shop  keeper  told  me).  
 
 2.  Not  damn  bright  as  people  say.  I  tried  the  30W  LED  floodlight.  They  were  pretty  low  in  light  intensity.  This  50w  which  I  have  got  is  at  least  close  to  a  3/2  PL.
 
 3.  The  LEDs  do  not  last  long.  1  ~2  years  is  something  which  you  can  expect.  The  driver  circuit  burns  down  if  your  power  is  fluctuating.  Use  a  stabilizer  if  you  got  one.  Expensive  ones  last  long.
 
 4.  I  replaced  my  144W  PL  (4x36W),  with  this  2  x50W  LED  floodlight.  The  intensity  is  definitely  lower  than  what  I  had,  but  have  to  consider  the  fact  that  I  am  still  using  44  W  less  than  PLs.  An  additional  50W  might  be  equivalent  to  the  PL  lights  but  then  I  do  not  save  on  my  power  bill.
 
 5.  A  bit  bulky  fittings.  I  had  to  literally  tear  off  the  roof  of  my  aquarium  to  accommodate  these  and  also  did  some  carpentry  to  get  those  bulky  fixtures  hanging  above  the  tank.  Believe  me,  its  not  a  good  sight  to  see  bulky  LED  fittings  hanging  above  the  tank.  You  will  need  to  conceal  it  with  a  taller  roof  like  I  did.
 
 6.  Shimmering  -  Though  looks  good  initially,  I  felt  having  a  soft  light  spread  across  the  tank  is  better  than  seeing  a  flickering  tank.  I  have  some  ripples  on  the  surface  created  by  the  external  filter  output  and  so  get  pretty  good  shimmering  effect.  It  was  more  pain  for  the  eyes  than  I  thought  it  would  be.
 
 My  opinion:
 Forget  the  10-30W  LEDS  if  your  tank  is  >  3ft.  They  are  good  but  only  for  smaller  tanks.  Might  be  if  your  tank  is  shallow,  you  can  go  for  10W  LEDS.  My  50W  LED  just  reaches  the  bottom  with  sufficient  intensity.  I  think  a  year  or  two  might  be  required  for  the  good  LED's  to  appear  in  the  market.  All  comparisons  in  the  net  are  for  those  expensive  ones  like  CREE.  Not  for  the  cheap  ones  now  available  in  India.
 
 I  have  an  array  of  1x16W  LEDs  which  I  think  are  better  than  a  single  50W  LED.  I  guess  a  50x1W  LED  if  available  would  be  a  better  choice  than  1  50W  LED  floodlight.  They  spread  wider  and  the  shop  keeper  said  the  life  would  be  better.

 I  can  post  a  pic  of  my  tank  if  someone  wants.  Reply  me  and  I  can  put  it  up.[size=18]

 I  like  your  concept  of  summarizing  your  experience  but  I  am  confused  4  days  back  sorry  3  days  back  you  were  asking  about  LED's  and  today  you  writing  a  review.Please  give  review  after  you  use  it  for  some  time.Also  there  are  so  many  companines  and  differnet  types  of  LED's  in  market  so  it  depends  upon  what  you  went  for.
 I  have  used  MH's  in  past  and  would  say  LED's  are  not  that  bulky  .3  Days  down  the  lane  you  cant  say  how  long  the  LED  you  bought  lasts  unless  you  ahve  proofs  .I  lit  my  recently  bought  30W  LED's  and  they  are  bright  enough  to  lit  my  tank.Also  out  of  your  4  posts  in  3  posts  you  are  mentioning  the  same  points  but  with  different  fonts  Smile  
 Could  you  please  post  pic  of  your  tank  with  the  lights

 Hi  Royalbijoy,
    I  totally  agree  with  each  and  every  point  you  have  on  LED  lighting.
 I  too  wanted  to  have  LED's  in  my  tank,  so  I  did  some  research  and  did  many  calculation  of  permutation  and  combination  on  wattage,  lumens  and  cost  of  all  the  LED's  plus  the  driver  required  if  going  for  a  DIY  array  and  also  went  through  various   flood  light  catalogs  of  Chinese  as  well  as  manufacturers  from  India.
    I  did  not  come  across  one  single  positive  reason  to  change  to  LED  lighting.
 Points  for  me  to  stay  away  from  LED..  whether  DIYing  or  flood  lights  in  India.
 1,  you  are  not  saving  much  on  power..  This  is  supposed  the  main  criteria  for  jumping  over.
 2,  The  cost..  cheaper  ones  don't  save  power,  power  savers  like  cree  are  way  -  way  too  pricey.
 3,  Reliability..  the  shop  keeper  says  "the  life  of  the  LED  is  5-6  years,  but  no  guarantee  on  the  driver  of  flood  light.  it  may  last  for  2  years,  but  you  can  easily  replace  it".

 Well,  the  three  other  replies  were  same  but  I  had  some  requests  to  start  a  new  thread  as  many  were  looking  to  buy  those  LED  lights  and  felt  mine  wasn't  easily  noticed.  So  thought  of  starting  a  dedicated  thread  for  the  topic.  I  would  like  to  get  the  other  three  deleted  if  possible,  so  that  we  have  only  one  version  of  it.....
 
 Anyways,  as  I  have  clearly  mentioned,  the  review  is  only  for  those  LED  floodlights  now  widely  available  across  shops  and  not  for  the  expensive  ones.  I  did  see  one  of  the  costly  ones  at  the  shop  which  might  just  do  the  trick.....  
 
 About  posting  a  thread  within  3  days  of  asking  reviews  about  LEDS,  lots  of  things  changed  in  three  days.  I  would  say  a  day  is  enough  to  get  to  know  the  efficiency  of  the  lights.  You  just  need  to  see  the  pearling,  spread  and  intensity  of  lights  reaching  the  bottom  to  know  how  good  these  lights  are.  
 
 I  would  like  to  mention  again  that  this  topic  is  only  for  those  LED  floodlights  as  mentioned  in  the  pic  and  not  for  the  expensive  ones,  which  are  really  meant  to  replace  T5s.....  Hard  to  believe  you  got  good  penetration  with  30W.  How  deep  is  your  tank?  Mine's  24inces  and  so  I  can  really  find  the  difference.....

 Just  FYI..  my  tank  is  2.5x1.5x1  ft.  I  tried  a  30x2Watt  china  made  LED  flood  lamps  top  and  they  were  pretty  lame  when  compared  with  my  T8  (80W)   Thumb Down     The  light  was  not  even  reaching  the  bottom  of  the  aquarium  properly.  Not  sure  if  it  was  because  of  the  brand  or  what  ever..  It  was  4K  price  here  in  Bangalore.  So  i  dropped  my  plan  for  LED  and  returned  back  to  T8  and  planning  to  go  for  T5  or  PL  upgrade.

 Hope  someone  had  posted  their  LED  experience  before  I  bit  the  bullet  and  brought  one.  My  only  suggestion  would  be  not  to  hurry  up  and  buy  one.  Its  definitely  not  awesome  as  people  claim.  If  you  want  that  awesome  experience  get  a  good  LED.  But  then  the  big  question  is  :  Did  you  really  save  big  bucks  in  moving  to  LEDs?????  I  don't  think  so......
 
 Unfortunately  my  camera  is  with  my  friend  and  so  cannot  take  a  pic.  Tried  using  the  mobile  phone  but  the  pics  weren't  so  good.

 I  personally  dont  suggest  led  flood  lights  to  any  one.  I  have  been  using  the  3watts  LED  for  all  the  led  setups  that  I  have  done  till  now.
 
 Here  is  my  tank  running  on  the  27Watts  LED  (3watts  each  led)

 so  here  is  the  question  again.
 when  u  need  27watts  of  light  for  around  20  liters  of  water.......  where  is  the  saving?

 I  didnt  say  anything  about  saving  power.  I  dont  know  why  everyone  are  keen  only  on  saving  power.
 
 >  Imagine  you  are  using  a  CFL/PLL  of  20watts  and  above  for  a  cube  tank  and  the  heat  generated  by  the  cfl/pll  tubes.  There  you  need  to  have  cooling  fans  to  lower  the  temperature  of  the  tank.
 
 >  Generally  people  change  the  CFL/PLL  every  year  to  get  a  better  spectrum/lighting  from  the  tubes.
 
 >  How  many  months  would  a  CFL/PLL  last?
 
 For  all  the  above  LED  is  the  best
 
 >  Less  heat  generated  by  the  light.
 >  No  replacement  required  every  year.  Good  LED  life  span  is  between  40000-50000hrs.  Considering  you  are  lighting  8hrs/day,  your  led  life  span  is  13  year  (considering  40000hrs  as  the  life  span)
 >  Gives  more  lumens/watt  (Good  branded  led's.  Not  the  cheap  chinese  led's)

 Dont  say  that  I  want  to  move  to  LED  to  just  save  power.  There  are  lots  of  other  facts  that  you  need  to  think  on  when  moving  to  led's.
