LED strip

I am looking for a cheap but bright 1m led strip (red or blue) to achieve indirect "mood" lightening behind some shelves. I was looking on ebay and there a generally two tipes of this led strips:

http://cgi.ebay.com/24cm-Flexible-Car-Strip-Light-Waterproof-24-LED-Blue-/130459197624?pt=LH_DefaultDomain_0&hash=item1e5ff960b8#ht_3059wt_1135

 

http://cgi.ebay.com/Flexible-15-SMD-LED-Blue-Car-LIGHT-Strip-Blue-/170545850208?pt=LH_DefaultDomain_0&hash=item27b5532760#ht_3026wt_1135

 

Which are brighter? Also I read some of the led strips lasts up to 5000 hours, which is way too short for my ussage. Can you recomend any good (has to be bright and  last at least 30000 hours) that is also cheap - sub 10$? 

 

Thank you!

Just be sure to NOT order anything that plugs to 230VAC without a real valid CE! Otherwise the package will not import. (po domače: te bo jebala tržna inšpekcija z neskladnostjo z EU zakonodajo) In English: The lack of EU conformity will block the import and the goods will go destroyed.

I was thinking something like this should be ok to power 2 x 1m of led strip: http://cgi.ebay.com/12V-5V-AC-Adapter-Power-Supply-HDD-HARD-DISK-DRIVE-IDE-/260491050625?pt=LH_DefaultDomain_0&hash=item3ca679fe81

SIcer sem že naročil eno pištolo za lepilo, ki laufa na 230V iz DX, pa ni blo problemov (I already had ordered glue gun from DX that is powered from 230V AC and there where no problems with costums). Maybe I was lucky ...

Probably lucky. I believe that thing will not do the trick. You lack current regulation. Since it is powered at 12VDC that suggest that they are wired 4 in series (4x3V per led reasoning) and then the 4-stack in parallel antoher 6 times.

The thing will require something around 6x 80mA total=480mA (4x20mA per single led). So you better try a regulated 12V 500mA adapter! Otherwise it will smoke pretty soon i think. I'm not much of an expert but i believe there is some truth in my reasoning. Let's ask the real experts which lurks here often. Wink

You are probably right... How about if I buy 4 strips - 4x0,5A and connect them together - will than the 2A power supply with no ocurrent regulation be ok?

 

Off topic about glue gun: sicer pa sem tisto pištolo za lepilo + 2 palčki lepilo dobil za manj ko 4€. Pri nas sem najceneje videl okoli 8€ - je pa res, da pri nas dobiš malo boljšo kvaliteto...

Those 2A are probably regulated and that should work.

Btw! Why don't you get these? http://www.manafont.com/product_info.php/3meter-30led-bluecolor-holiday-...

For the little times you need that.

I think these ones are not bright enough (power from 3xAA)  + I will probably keep them on all the time + strip almost needs to be adhesive - to stick to the back of the shelfes. Otherwise these ones from manafont are increadibly cheap per m...

Or you can try get for a beer an adapter for T-2 ip-phones from a technician. Wink 12V-1000mA almost free if you have the technicians around. Smile

OK so in the end I bought something similar to this: http://www.dealextreme.com/details.dx/sku.23843  ofrom ebay for 6$ just because my mum bought the same lights from local store for something like 15€ and I really like them - pretty bright. Are this lights dimmable of 220V?

Lol this guy here: http://hdhl.de/index.php?option=com_content&view=article&id=11&Itemid=14 went a little crazy with those cristmas lights Smile

Our costums really sucks! To pa je bedno, sicer čisto razumem zakaj naj bi bile nevarne - laufa direktno iz 230V.
