DIY Multichip LED Build

[007Bond]

Cool idea! Be neat if the two were threaded... twist to the right, twist to the left you could change the optic degree. Would fit a lot of different solutions. Is AC-RC going to be selling them?

[ronreef]

Yes, AC-RC will be selling the adjustable lens. The two parts move. You have the right idea

v2 is on the back burner at the moment.

AC-RC will be selling a kit to attach the coolers they sell to the goosenecks they sell.

Early design of the adjustable lens.

They'll also be selling a multi-channel controller. Neat!

I'm building one of those Jarduino's. It dose a lot of cool stuff, especially with the 5 channel DC. Going to drive it with the LDD's

Please post when they have the adjustable lenses for sale.---Rick

Good to hear about the new things AC is developing.

Can any1 share how your red corals doing under the dream chips?

Mine seems "washed out"

[Lasse]

Which type of corals? I have rusty red mushrooms, an orange-red ricordea and fishes with red and it works good in colours for me. I have one Dream Chip with red in it (630 and 660 nm) and I have tried to compare the different chip´s but I can not see that there is any major difference. But maybe you can get that effect if you have corals with a lot of reflectant red pigments in it. Is there any differnces if you run with a lot of blue or with a lot of white lights?

The coral I'm referring to is a red lobophyllia which used to be a very red and now is a pinkish colour, my mini carpet anemone used to be a deep maroon color but now lost most of its red colour.

I want to show you how I built my multichip fixture.
I have used Janne_68 control cards and driver board and 5ch driver board.
2 pcs dream chip and 32 pcs 10W led is what I have in the ramp.

This is the spectra comming out from my 120 gallon´s front glass. Two 100 LED Dream Chip and one 50 LED Dream Chip.

Hi

I´m comming back with more experiments with my spectroscope. This type of capturing a light source spectra is a low cost and a simply method. I do not suspect that I will get a exact figure of the actually spectra but it will give me a hint. The Public Lab Desktop Spectrometry Kit is easy to mount and rather easy to work with.

The other day I made some measurement and I star to take a picture from the sunlight outside my window, just to get a reference. The web cam I use has a IR filter and I did not take it away. Probably this filter is the reason why I do not wavelengths higher than 650 nm.





It is very difficult to mount the spectroscope in such a way that you do not get to much intensity. I decide to take my spectra on the light coming out of my tanks front window and to run my three dream chip at 30 % of a total input of around 440 Watts ( around 130 W) I took my measurements at the middle of the tanks front window. I had the spectroscope mount in the same way in all of the following measurement. it means that you can compare them. At the first measurement I run all channels at 30 %



After this I capture the actinic, the blue and the white channel by them self and put them together in one graph in order to compare each main channel contribution. (Each line is the channel named in the legend - forget the 0 % - they are all run at 30 %)



I was also interested to see what happen if I varied the intensity of blue and white channels. This picture shows how it looks like if the blue channels (actinic + Royal Blue) was run at 30 % and the white channels at 70 %.



And this picture show the opposite
