Scrubber build

Hmm unfortunately I have no equipment to test anything. I recently added another maxspect razor and unplugged the wire for a few seconds while the unit (and driver) of the maxspecr were still plugged.. could that have influenced the driver from the scrubber? I ordered 2x LPC-20-700..

Also checked the water quality. It is already quite "dirty" no3 4.0 and po4 0.1. So I will cut back on feeding and wait for the algae.

Unfortuntely not. I will have to wait for the drivers I ordered.

I wonder if I ordered the wrong driver... LPC-20-700...
10 x red = 0.7A x 2.5V = 1.75 W per led x 10.. is 17.5W. 2.5W remains. and the semileds 420-425 are slightly more powerfull I believe.. more than 1.25W per piece. I have 1 of them.. so.. think I will have to use 1 led less.. unfortunately.

That is a good idea! I'll do that. Regarding the violets. I could wire them parallel indeed, which would run them at 350mA.. and wire each 660nm in series.. I will end up with 3 driver that way, I believe the semileds at half power would be better for growth if I am not mistaken? Unfortunately I will have to remove the silicone though. the algae will have no light for 2 days at least (as I will need to let the silicone set) I do not know if the algae will be killed then... ?

The algae is growing slowly;

I forgot to mention that the lights are now running for 12 hours on.. 12 hours off.

No, I used packaging tape on the sides to make some sort of a mould. Used 2-component clear silicone and poured this over the leds, in a few days the silicone sets. It will attach to the alluminium very loosely. It is just there to protect the leds from moist and bumping. I removed the tape last time, but will leave it there so the silicone will stay in place better.

I never knew it was possible to connect 2 leds parallel within a serie. I think you just saved there, I can now use the LPC-20-700. I will first just attach the new driver as soon as I receive them and see if all leds still work.. if not I will try the battery thing to test each led. Do you also have a picture of the batterie device by any chance?

Thank you for your help!!!! Your the best!!

Kind regards,

Tim

 

I think I messed up somehow... this is what happens when turn on the power (new driver)

I could not find a 9V batterie yesterday.. I'll buy one today and test the leds.

Unfortunately I do not own such a meter. I will have to buy one if the battery test does not solve the issue. What you hear on the video is the power switch.. So as soon as I turned off the power the leds stopped glowing after a few seconds. I can onlu repeat the flickering after some time... if I would turn on the power right away.. the leds glow and nothing else happens.

I purchased a 9V today to test the leds;
as soon as the led is hit it burns very bright.. and quickly stops burning... I thought this was due to the fact that the leds were still wired. So I had one 425nm spare to test.. After a few seconds also this led stopped burning.. which made me realize I just fried all my leds.

Damn it.. I should have read the comments..

Make Your Own LED Light Bulb Tester From 9V Battery!

.....expensive mistake.
