 Two  Foot  stick.  Super  Bright.
 
 
 Check  out  the  other  LED  Items  this  guys  is  selling.
 
 First  I  thought  of  doing  my  own  LED  lighting  in  diffirent  colors.
 But  this  cuts  out  all  the  headache
 
 And  you  can  get  them  in  different  colors.
 Ive  placed  an  order  and  will  take  some  pics  as  soon  as  it  comes  in.[url=http://cgi.ebay.in/LED-TUBE-50-white-led-encapsulated-in-0-75-pipe-2-feet_W0QQitemZ140319850862QQcmdZViewItemQQptZLH_DefaultDomain_203?hash=item140319850862&_trksid=p3911.c0.m14&_trkparms=66%3A1|65%3A1|39%3A1|240%3A1318|301%3A0|293%3A3|294%3A25#ebayphotohosting]LED  Strip[/url]

 Hi  Chinoy,
 
 This  is  similar  to  the  LED's  strips  that  we  sell  except  ours  have  LED  drivers  and  these  have  resistors.  However  these  are  only  good  for  moonlights.  Will  not  replace  a  regular  tube.
 
 The  pictures  that  you  see  are  clicked  when  the  room  lights  have  been  turned  off.  Also  LED's  are  extremely  directional  unless  you  have  a  diffuser  on  it.  However  if  you  use  a  diffuser  then  the  depth  will  reduce  extensively.
 
 Cheers

 Cool  I  will  check  them  out.
 Ideally  Im  thinking  of  a  PIC  controller  to  cycle  the  colors  based  on  time.
 With  Blue  and  white  being  the  two  colors.
 
 Im  thinking  of  2  or   3  strips  along  the  bottom,  and  top  and  sides.  This  is  in  addition  to  the  lighting  on  the  cover  of  the  tank.
 Which  will  be  one  or  two  tube  lights.
 These  strips  will  be  hidden  along  the  sides.  Behind  the  Black  tape  I  plan  to  put  to  cover  the  epoxy.
 
 This  would  give  enough  light  for  night  time  viewing.  During  the  day  the  tank  has  sunlight.
 
 Do  you  guys  stock  the  5  watt  Leds.
 Ive  e-miled  this  guy  to  find  out  how  many  watts  these  bulbs  are.
 
 Ive  sent  you   a  PM  on  what  my  plans  are.
 
 Since  your  in  this  line  please  try  and  import  that  Ammonia  alarm  I  had  posted  a  link  for.  Which  was  removed  I  guess.
 Its  only  4-5$  and  it  works  for  a  year.  warning  you  of  your  ammonia  levels.  It  shows  from  low  to  high  4  levels  are  displayed.
 Im  sure  it  will  sell  well.  I  will  buy  one  for  sure.

 These  LED's  wont  be  in  Watts.  Their  specification  says  the  total  consumption  is  10W.  If  it  has  50LED's  then  it  can  be  Watts  ..  These  would  be  either  5mm  or  8mm  or  10mm  LED's.  Such  tubes  are  available  in  Delhi  at  the  local  market  at  probably  1/2  the  price  mentioned  on  Ebay.  But  none  of  them  have  had  a  longterm  life.  This  however  is  my  personal  experience.  May  differ  from  peice  to  peice.
 
 As  far  as  your  placement  of  these  strips,  I  am  not  sure  how  it  will  look.  Is  this  tank  at  your  home  or  a  hotel.  The  reason  i  ask  you  this  is  cause  at  home  it  wont  look  too  sothing.  At  a  commercial  place  you  could  try  to  attract  the  attention  of  the  eye.
 
 If  you  want  night  time  viewing,  i  would  suggest  you  just  fix  the  strip  inside  your  hood.  Just  one  Make  a  combination  of  blue  and  white  LED's  in  the  strip.  This  gives  a  fantastic  moonlight  effect.  
 
 However  the  above  is  just  my  opinion.
 
 We  dont  stock  5W  led's  cause  they  are  too  expensive.  They  are  available  in  India  at  some  manufacturers  but  the  quantity  you  would  need  to  buy  from  them  is  in  1XXX.  The  price  of  each  are  also  X,XXX

 Its  for  my  home.
 So  your  saying  one  strip.  Along  the  roof.  One  strip  of  blue  and  one  strip  of  white.
 
 Im  glad  I  made  this  post.  It  led  me  to  your  site.  Which  has  some  interesting  items.
 Had  no  idea  that  people  where  allredy  selling  this  stuff  for  the  hobby  as  I  didnt  see  it  in  any  of  the  LFS.
 
 Can  your  strips  be  placed  under  water  ?
 
 I  have  some  contacts  in  the  electronics  field  so  will  try  and  source  a  few  5  watt  Leds.
 They  would  make  good  spot  lights  on  the  caves  I  have  planed  with  the  right  diffuser  off  course.
 
 I  have  see  some  single  LED  key  chains  where  a  single  LED  can  light  up  a  room.  (When  dark).

 Another  interesting  LED
 
 http://www.dealextreme.com/details.dx/sku.20999
 
 They  even  have  one  which  gives  you  the  equivalent  off  a  10  watt  CFL  from  a  single  LED.
 Prices  are  high  on  this  site  because  it  includes  shipping.  
 
 If  you  can  find  a  source  in  India  it  would  be  way  cheaper.
 
 Ps:  I  tracked  down  those  super  bright  LEDs  22000  MCD  not  a  joke
 
 http://www.lsdiodes.com/shop/index.php?main_page=product_info&cPath=14&products_id=37
 
 And  a  really  cool  place  for  all  things  light.

 Ron,  I'd  love  to  see  the  tank  once  you  have  the  LEDs  up  and  running.   Very Happy

 Lsdiodes  no  longer  sells  LEDs  anymore.  As  far  as  the  high  power  LED's  goes.  They  all  heat  up  extremely.  Thus  making  a  compact  fitting  to  suit  our  aquarium  need  may  not  be  as  easy  as  it  looks.  
 
 Also  if  you  consider  the  cost  factor  of  these  LED's  vs  Life  of  high  power  led's  in  our  moisture  driven  environment  may  not  be  really  that  long  as  we  may  believe.

 sure  nash  all  very  valid  points  I  will  probably  go  with   your  strips  only.
 
 
 Today  was  the  deadline  by  which  I  was  supposed  to  have  the  stand  done.
 The  wife  was  not  impressed  that  my  load  analysis  module  in  auto  cad  wasn't  working.
 
 So  a  local  stand  maker  was  called  in  and  my  cad  drawing  was  handed  over  to  him.
 Lets  just  say  the  stand  has  landed  up  costing  more  than  the  cost  of  the  tank.
 And  the  filter  is  going  to  cost  more  than  the  tank  or  the  stand.
 
 So  much  for  budgets.
 
 
 Now  I  have  to  sort  out  the  filter.
 Very  tempted  to  just  buy  something  ready  made.  vs  trying  to  build  a  sump.
 Budget  for  the  month  blown.     Crying or Very sad

 A  lot  of  people  in  the  UK  have  used  Dealextreme  for  making  High  power  LED  units  with  proper  heatsink  and  acrylic  enclosures.  I  have  however  yet  to  try  it  as  the  cost  of  the  Cree  bulbs  +  heat  sinks  +  Drivers  +  enclosure  makes  the  unit  very  expensive.
 
 Does  anyone  in  india  do  such  units?

 Hi  Nimat,
 
 I  have  sourced  some  Cree  bulbs  here  in  india,  1W,  3W  and  5W  and  some  experiments  are  on  in  my  DIY  center.
 
 Challenges  that  we  are  currently  facing  is  surely  heat.  However  we  have  now  taken  care  of  that  by  using  the  CPU  Intel  Fans.  Enclosures  is  the  last  thing  we  will  make  based  on  the  final  design  we  come  up  with.  
 
 However  still  in  comparison  to  MH  or  other  bulbs  the  light  spread  is  definitely  not  upto  the  mark.  I  am  awating  an  LED  diffusor  that  i  have  ordered  from  HK.  Hope  fully  that  should  do  the  trick.
 
 Warm  Regards
