|DanW11||This looks outstanding, the LED lighting has definitely worked well! I'd say this is one of my favorite 'tree' scapes in a nano tank, nicely done.|

Another update of my nano tank. The pictures date is 19 May 2012
The pic. show clearly the rate of growth plant after pruning (1 May 2012)...
I'm very happy. I can say that the "led" experiment is successful!!
Ciao and thanks all... Christian

we calculate the consumption of the led light.
The image shows the working point of an LED (extract from Cree XP-G led datasheet). Each LED is powered by a constant current of 700mA. With this current, the voltage across an LED is equal (approximately) to 3.2 Volt.
The power consumed by each LED is given by:
P = I(current) x V(voltage) = 0.7(Ampere) x 3.2(Volt) = 2.24 Watt
The total power consumed by light is only:
Ptot = P x num.leds = 2.24 x 5 = 11.5 Watt
I leave you comments ...

The led driver is 700mA (28 Watt) constant current driver without dimmer.
The my model is: http://www.bizetashop.it/shop/20000-...-drv-700ma-28w

|ptr||Really nice ! Which driver did you use for the leds ?|
|05-01-2012 08:37 PM|
- Components are buy here (sorry but the sites is in italian language ):
1 - Heatsink buy here: http://www.xled.it/prodotti/accessori/#ar03s --> Dissipatore per led 3-5 Watt
2 - Cree LEd buy here: http://www.bizetashop.it/shop/10000-...0-r4-xpgwht-r4
Is not possible attach the led directly on the aluminum bar because the profile is too thin and therefore not able to dissipate the heat produced by the LEDs

|kuro||That tank look really good. The diy led where did you get the heatsink from? can you skip the heatsink and just put the led directly on the aluminum bar?|

|Hadouken441||This looks great. Im going to have to try this DIY led thing. Looks amazing|

this is another update of my nano tank. The pictures date is 01 May 2012
The lawn mower has passed...
What do you think?

The moss is Taxiphyllum barberi.

If you hit the alert button and ask there, they should move it for you. I've seen them use the alert button this way in the past.
Nice tank. Do you know what kind of moss you have?
|04-20-2012 07:23 PM|
Sorry for my second request....
Is possible to move the my thread in the tank journals section??
Ciao and tanks...
|04-18-2012 07:14 PM|
I ask the moderators or administrators to move the thread in the tank journals section.
Ciao and tanks Christian
