Since i have 2 led bars with 27cm, if i get 2 heatsinks with 30cm each, that´s ok. I´m frustrated because i can´t find anything. I read in the net that the heatsinks sold by lumitronix get to much hot, so i suppose i need a heatsink with more surface area. i discover one case with heatsink, but i´m ...

Here in Portugal there aren´t heatsinks in bars with 1m. The only heatsink that i found in the best electronic shops, are with 10/15cm lenght. There is a Fischer importer but the minimum quantity to import is 3 bars of 1m, with a irracional price. Does anyone know where i can find the SK25 or the SK...

Where can i buy a heatsink like that?

Does anibody know where i can buy a heatsink like the one for SMD leds, but with more dissipate power.
I need one with some kind of place to put a acrilic cover to isolate the led bars from humidity.

Ok,

So this means that i need to buy another heatsink.
And about the power supply that i have 24V, 2.1A.
If i get another heatsink, do i have to change the power suply?

Tank you

For the two cree bars and the heatsink/case that i mention do you think that is better to change the power supply (if necessary i could change it in the store)
If so what do you advice from this: http://www.mauser.pt/catalog/index.php?cPath=23_722_723

Sorry but i don´t understand German.
I try to translate the text to English and Portuguese but it was not accurate.
It´s possible that i understand that the cree bar work 24v with 500ma?

Sorry about all this questions but this systems are a bit expansive and i don´t wont to make any mistake.

The tech spec of the cree bar said that the current must be 600-1400 ma. and the voltage 15-30v. http://www.ledrise.com/product_info.php?info=p251_Extreme-Line-Plus--Warm-White--8-CREE-X-RE-Q2-LEDs--960lm--90--176---powersupply-included-for-15-30V.html The Ledrise shop wasn´t very accurate about the...
