Ciao guys,
these are some photos showing how I built the lamp...

Ciao guys,
this is another update of my nano tank. The pictures date is 01 May 2012

The lawn mower has passed...

What do you think?

Ciao and thanks... Christian

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

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?

BlackHoleVR · 05-01-2012, 08:37 PM

Tanks all.

- 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

Ciao Christian

Really nice ! Which driver did you use for the leds ?

BlackHoleVR · 05-01-2012, 08:55 PM

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

Ciao guys,
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 ...

Ciao ciao Christian

Ciao guys..

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

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.
