    hi all

    i wanna share with everybody my custom LED light project. as the title says its a re-build because i bought the light from a MASA member and because it was not gonna fit the tank i wanted to use it on i decided to completely re-build it using all the old parts. So thanks to @Shaun88 for selling me his DIY unit which was so well build.

    in my re-build i'll not use all the LEDs that came with the original light. my unit will consist of

    22 x 3W CREE XT-E Royal Blue
    16 x 5W CREE XP-G R5 Cool White
    6 x 3W Red
    3 x 3W Green
    2 x UV
    4 x Moon Lights

    also i have:

    4 x MeanWell ELN-60-48P Dimmable Drivers
    1 x Typhoon Controller
    2 x 8cm Desktop PC fans (12V)

    the plan is to have two of the MW Drivers running the blue LEDs with each controller running 11 LEDs @ 1200mA and both controllers connected to Channel 1 on the Typhoon controller. The third MW driver will run all 16 cool white LEDs @ 1200mA on Channel 2 and the fourth MW driver will run the six red, three green and 2 UV led @ 650mA on Channel 3. The moon lights will not be connected to a driver but to a 12V power supply instead. the reason for that is because the MW ELN-60-48P should not run less than 8 LEDs connected to it and i felt it would be a waste of time and money ordering just 4 extra LEDs from RapidLED.

    the light will be used on my new system (i'll start a thread later). i wanted use it on a tank of 120x43x53 but because my house is too small and my girlfriend was complaining that the new tank was gonna take up half if the living room area i decided to build a smaller tank which will be 100L display volume.

    pictures to follow :)

    ok it all started with removing the LEDs from the old heatsinks, cleaning them and testing to see if they all work

    also few different layouts for the new build

    to test the LEDs i used 2 x AAA batteries connect one wire to the + and the other to - and the LED should light up if its working

    next was to organize a new heatsink.. after a long search and almost getting to the order the expensive heatsinks RapidLED sells someone on this forum suggested i check at MANTECH

    i bought two 100cm x 10cm heatsinks because i wanted to make the light 1m long to fit over my 1.2m long tank. Each cost me 337.44 incl VAT which i thought was a great price

    so i took the two heatsinks to a friend of mine who has an engineering shop and he welded them together so i can have one heatsink of 100cm x 20cm

    sounding interesting, so I'm definitely going to track this as I'm about to re-build my own DIY LED build! I've just been searching for an aluminium distribution company that sells heat sinks - to no avail... So I'm over the moon that you mentioned Manco, I will contact them...

    From what I've heard aluminium welding is quite specialised and tricky, so it's a good job you had a mate who could assist you!

    @coralline im not sure if its really that dificult or even different from normal welding.. i think the main difference is in the welding rods, i think aluminum rods are more expensive. any engineering workshop should be able to assist you

    so after deciding not to go with a 1.2m long tank i had to rearrange my plans for the LED build.
    this is the tank that the LED are intended for now

    IMG_20131011_210833.jpg

    its an AQUARIA 102 liters that i have removed the hood from and the back compartment. i have and overflow build and will have the sump and all the other equipment in the cabinet under the tank

    so i took the heat sink back to my friend from the engineering shop to cut it for me.. and this is the result

    IMG_20130917_143249.jpg

    i drew a grid on the heatsink so i can make sure that all the LEDs are aligned properly
