Mikaila: First none taken, This project was done in a effort to offer something that I felt the masses could do. I do know that with the LED lights you talk about would require some solder, an iron and some know how in electronics. If you were to do just the 4 or 5 moon lights then it would be easy to wire up with very little work but anyone who would try it would have to understand the placement of the resisters, serial, and/or parallel configurations. Now when going into a much larger configuration such as this project with 200 LED's it is worth the extra cost to have that wiring done if the Person doing it doesn't understand resisters, Ohm's law, etc. that way they don't not have to worry about it. Now you can also go to ebay and find the LED lights in 100 count strands for under $5.00.(it can also take up to a month to get them) I could have went that way but I like to support my local small town hardware store. It's up to the person doing the project to decide if it is worth it to them. this project may not be to your standards or done the way you would do it but to others it may be right up their alley.

I also want to thank you for posting and I hope you have a wonderful day!!!

i think moonlights in general are bad for live plants, it kills their dark ours and they dont grow properly. I think you should leave the wirenest... looks kinda like your growing a curly chia-pet on top of the light fixture... I really like this project.

I would like to ask a question though, if one of the leds burn out, how do you replace it without taking everything apart? I feel like pulling one light up to change will make u pull out several and then you gotta put em all back in... etc.

And an upgrade tip, if you line the pvc with aluminum foil, or any other shiney reflector-like material, you could have probably gotten away with less LEDs for more light. White surfaces are good, but metallic ones are better. Also with the foil, you can get the ripply water effect, <-- i dont know what its actually called, but u see them in pools in bright sunlight...

I think i will be adding a smaller version of this project to my to-do list... maybe like 3 leds for my 1g tank. Does anyone know where individual LEDs can be bought? and how to wire them?

SinCrisis: there are 3 inches between each light so its not hard to pull one and replace the led. It plugs in the same way as the older Christmas lights. I had to pop a few when i started and I just used a small pick that I have to push it back out. It works great. I have a site I like to use to run calculations with and it shows some of the basics of wiring them up. If you would like I could send you a link in PM. If you are only doing 3 it will be super easy. The power source and resisters will be determined by the type of LED's you chose.
I'm sure between myself and many others on here we can help you get it done

Yeah I don't have a reasonable answer as to why I didn't use the foil. I knew about it but when I was working on it I just forgot about it.

Thats fine if people want to use this method. But how big is this tank? Moonlights IMO are suppose to be dim enough to still allow the fish to sleep. Brighter ones can be used you just need to make sure your fish do have a period to sleep. Also I am much too lazy to even use the cordless iron we have. I believe in the power of tape and hot glue!

Moonlights won't hurt live plants at all. They probably won't even notice the light. Wild plants grow under the moon just fine...

its a 29 gal tank. the moon lights are on a timer along with the other lights. they get white light for about 12 hours then get moon lights for about 4 hours then it all shuts down untill the next cycle starts. I do think that 100 blue led was too much. It's something that I learned after the fact. I really didn't expect them to be so bright. If it was a larger tank they may be fine. On this 29 I think the blues are too bright. If I was to do it over I would go with a strand of 50 or 60 blues

Yep. :)


Also, the real funny thing about those lights, is that it actually IS fairly close to one of the spectrums for plants. 440nm (blue) is one of the frequencies in the highest demand for photosynthesis. Of course, there are several other frequencies that you need (660 being another important one.) to balance it... If you have too much red, blue, green, or orange, then algae takes over.

Just wanted to correct it. :)

Which I find kinda amusing considering the cost of the camera you used to take a picture of it
