 Hi,  Veeral
 I  am  now  using  2  x  36W  PLL.   As  I  want  to  reduce  the  electrical  consumption  I  want  to  go  for  LED  s  which  consume  less  energy.
 If  I  go  for  90W  of  LED  where  is  the  reduction  of  energy.   I  can  stick  on  72W.   In  addition  I  am  having  2  x  24W  T5  SHO  which  I  am  not   using  now.   If  I  want  to  go  for  90W  LED  I  can  go  directly  to  120  W  of  PLL  plus  T5  SHO  without  making  further  expenditure.
 Thank  You.

 Hi
 I  recently  stepped  down  from  a  70Watt  MH  to   30Watt  LED  floodlight  on  a  18  Inch  cube.  Have  kept  the  LED  at  about  4  inches  from  the  water  surface  since  it  produces  much  less  heat.  Practically  all  the  plants  have  taken  a  hit  in  their  growth.
 I  would  agree  with  many  other  that  here  that  you  really  cant  step  down  on  the  wattage  if  you  are  using  the  Chinese  LED  floodlights

 1+  with  Unni,
 
 The  led  flood  lights  that  has  come  to  Indian  market  are  no  where  efficient  in  terms  of  electricity  and  lumens.  Most  of  them  are  chinese  make  and  does  not  produce  enough  lumens  which  is  required  for  out  planted  tank.  And  there  are  not  energy  efficient.  As  mentioned  by  mortis,  its  better  to  use  the  normal  T5  light  rather  than  wasting  money  is  using  the  flood  lights.
 
 Here  an  experienced  aquarist  has  expressed  his  views  on  led  flood  light.  Its  clear  that  plants  dont  get  the  enough  spectrum  for  proper  growth.
 
 I  would  say  that  flood  lights  are  only  good  in  the  cheap  price  and  no  where  can  meet  the  efficiency  of  good  led  lights.

 Seriously  the  only  benefits  of  LED  floods  over  T5  is  the  shimmer  effect  and  that  too  only  if  you  like  it.
 
 Since  you  have  the  T5  HO  fixture  already  why  dont  you  use  that  ?  Keep  it  closer  to  the  front  of  your  tank  that  way  intensity  will  be  high  enough  to  grow  foreground  plants  and  at  the  back  you  can  have  some  low  tech  stems  or  crypts  and  anubias.  Thumb Up

 A  liTTle  more  seriously,  it  does  seem  to  work  for  few.  Just  like  -  "chalta  nahi...  daudtha  hai",  spectrum,  intensity,  plant  colour  and  shape...  you  name  it!
 
 This  guy  used  40W  LEDs  X5pcs  on  his  6ft.  I  am  sure  not  many  on  forum  have  same  standard  of  plants  as  his.  Atleast  2nd  only  guy  I  saw  with  such  a  lush  UG  foreground  rug.  Unfortunately  he  keeps  such  low  profile  for  some  reason.
 
 
 
 Here  is  link  for  further  details.

 Hi  Shelly,  Mortis  and  Saikumar,  
 Thank  You  very  much.     
 The  comments  leads  to  say  no  saving  of  electricity  mainly,  and  I  think  I  have  to  accept  you  three's  suggestions;
 Thank  You  Once  again.

 I  am  using  34W  Philips  PL  L  for  my  18"  cube,  its  worht  it,  you  can  attach  1  more  34W  PL  L  to  its  choke/balast-  it  gives  little  heat  but
 
 and  for  my  2ftr  I  am  using  2X  20W  T5,  now  here  it  is  very  powerful  then  the  chinese  20W  and  it  lasts  for  3  yrs  and  electricity  effeciency  also.
 
 Uni  could  we  see  a  picture  of  your  lights  please?

 @radjanair  sir,
 
 As  we  have  spoke  on  phone  it  work  for  some  people  and  doesnt  work  for  some  other......
 Seeing  aquadreams  post  it  is  evident  that  it  has  worked  both  in  power  effieciency  as  well  as  in  plant  growth  for  him.....  Getting  that  kind  of  growth  in  UG  is  not  that  easy.......  The  key  is  to  get  the  same  light  he  had  got  and  the  tussle  is  that  in  Chinese  made  they  don't  write  anything.

 But  do  ask  him  how  many  times  he  had  replaced  the  led's  and  the  driver.  Do  ask  him  how  many  times  the  driver  has  conked  off  and  the  led's!!!!   Thumb Down

 What  some  people  fail  to  realize  is  that  its  not  the  lights  that  are  the  most  important  thing.  CO2,  ferts  and  flow  also  have  a  huge  impact.

 I  checked  up  with  a  reputed  LED  dealer  in  Mumbai  who  sells  LED  flood  lights  with  Japanese  (Citizen  make)  COB.
 
 He  claims  Chinese  LED  flood  lights  produce  only  50  to  60  lumens/watt  and  there  is  a  deficit  in  lumens  comparing  to  original  ones.
 
 The  original  ones  produce  90  to  100  lumens/watt  and  the  price  is  4  times  higher  than  Chinese  one.  
 
 He  is  ready  to  accept  orders  for  customized  LED  fixtures  for  aquarium.   One  can  achieve  the  right  spectrum  for  plants  by  combining
 
 cool  white  +  warm  white  and  royal  blue.   IMO  you  have  to  choose  the  right  and  quality  one  if  you  go  for  LED.

 Plus  also  mention  Veeral  what  the  size  of  your  tank  is  and  how  many  watts  of  the  flood  lights  you  are  using.  It  looks  like  20W  over  a  nano  which  well  doesnt  look  to  good  in  favour  of  the  floods
