Diy LED light for a nano aquarium

[chuande.petrauskas]

So just finishes a build or like i call it fast mockup of light for my 27 l nano aquarium, dont mind a scape because its a temporary home for a shrimps. LED's i used was some 1w 6500k warm white ones, also there is a one 4000k cold white, still waiting for myred's to come and another heatsink to do a another with proper optics and dimmable.

Looking very nice.
So 'just' a pcb attached to a heatsink attached to a gooseneck?
All home made? Looks like that gooseneck is made from a piece of metal piping coming out of a project box.

Its a LED stars attached to a heatsink and all wires goes to a aluminum pipe bent with bare hands ( this is how men bend pipes ) and then yeah to a project box which contains a driver and also added a improvised dimmer which also must be placed into that box, also added a small fan because 6w of LED's heat a lot on that small heatsink [DOUBLEPOST=1409133129][/DOUBLEPOST]Almost all things were idy, except heater and filter

This is how it looks inside, actuali just finishes whole wiring thing and some other things, now its up and running

So after adding a two 4000k ones and two red's 660 nm i need another driver for them, because at full power they start to blink so im guessing that a driver is not capable enough to pull them all at full power, also changed a heatsink and looking at my stash another fan, a bit thinner and more capable to not be a loudest thing in the room even at low voltage levels its kinda strange because this driver is rated at 18w and im not even at half of this all with 8 led's
