View Full Version : 6' Artificial Tree Pixel Question

So I was at Walmart yesterday and they had trees half off. They had some nice looking (at least the pic on the box) un-lit artificial trees for $10 on sale, so I bought four of them. I plan to toss these in the yard next year with some pixels but don't know how many would look good on each tree. I was thinking maybe 100 pixels each, but maybe 50-75 would also look good? Any more than this and it gets expensive. LOL. The trees are 6' tall and I believe the box said about 2.7' wide, so they are pretty narrow.

I assume you are talking about actual trees with branches, correct?
If so, i think you could probably do 100 pixels and it would look good. The thing is with pixels they usually come in strands of 25 or 50.
With the thicker branches, I think you'd need atleast 100 pixels.

I know the 5v ones I purchased from Amazon here (http://www.amazon.com/100pcs-Diffused-Digital-Pixels-Addressable/dp/B00MECZ06G/ref=sr_1_1?ie=UTF8&qid=1419862883&sr=8-1&keywords=ws2811) are 100 pixels total (2 x 50px strands) shipped for about $50.
Also, check out my thread here (http://doityourselfchristmas.com/forums/showthread.php?36718-WS2811-Pixel-Spiral-Trees).
These trees are 6 foot spirals, and I used 100 pixels each and they are really bright, but theres not branches to diffuse or block the light of the pixels.

I believe these are the ones I bought. With how narrow they are, I was thinking 100 pixels would look good. I don't want these to over power the main pixel tree, which this year was an 8' tree with pixel strips. Next year's show, this might get changed to individual pixels and the strips re-purposed to arches.

As far as the pixels, I bought two 100 count strands from Ray Wu for this year's show. One of them I used to wrap a tree trunk towards the back of my yard and it wasn't that noticeable since it was behind everything. I plan to re-purpose this strand.

These are 4 foot trees with 50 pixels each. I'm going to add 50 more to them this year. On a 6 foot tree I'd go with atleast 100... Probably 150. 26668

Just like DS just posted, I did 50 pixels on my mini artificial trees that were three foot tall. For three foot, it was just right. I think DS could probably go with 75 on those trees. And 100 might be cutting it close on a six foot tree... If they really are that skinny, 100 might suffice.

What I did with my mini trees, since I was doing 48 of them and wanted to make sure I ordered the correct number of lights the first time, was to take a string of 50 and see if it made me happy. It did and then I did the same in figuring how many lights to put in my two foot artificial micro trees... that number ended up being 25.

Here's some videos

Thanks guys! I guess I could always open up one of the trees and test fit a strand to see how they look.

Louie,

Very nice setup.

What controller are you using ?
Are your pixels DC5v or 12v?

What type of connectors / gauge wiring you using ?

I had some issues w signal loss on my 20gauge wire and I wasn't running nearly half that length. Jw

Thanks,

Brad

Brad,

Those videos were recorded with the trees hooked up to a j1sys p12s controller, but the trees ran in the display with an advatek pixlite16 controller (controlling all 48 trees using dual 350w power supplies). Those pixels are all ws2811 5V. There are 16 outputs on the pixlite16. 8 for the 16 three foot trees and 8 for the 32 two foot trees. Each output is in charge of only 100 pixels with data+power connected at pixel 1 and power connected again at pixel 100. All supply cables and extension cords in our display come from Ray Wu. These were the standard black 3-core waterproof type, let me know if you're not familiar with those. I think they're 20AWG. I run 5 foot pigtails from the controller out of the case and then a 10 foot extension cord to pixel 1 on the string. Controller is placed in the center of all the trees so that every tree is reached with a 10 foot cord for both data+power and power injection.

Louie,

Awesome setup and good stuff on the detailed info.
I am def going to use it to help with mitigating data signal loss in my display next year!

Thanks again!

I have 16 - 6' trees in my display with 100 count M6 Led's and they look fine when only one color is on.. I did cut the bottom tubing down to about 4 " just enough to put the base back on so that they sit lower to the ground like a real tree might Also i punched out the center of the plastic base and then drive a 30" piece of rebar in the ground about 15' and then set the tree tubing/base over the rebar. Even with 50 to 60 mile and hour winds they will not blow over. I do spay paint my rebar to reduce grounding.

I went ahead and unboxed one of the trees and wrapped it with the 100 pixels that were on my tree trunk. I think it's perfect.

The trees aren't really 6' either. There's a top limb that is way longer than it needs to be adding an additional 6" that doesn't look right. I'll also be cutting some of the base off to get them closer to the ground and they will end up about 5' overall, which is closer to what I was after anyways. I'll need to reinforce the trunk since it's pretty flimsy in the wind and anchor them to the ground, but for $40 for all of them, I'm pretty happy!

Looks great!

I think those look perfect! Congratulations! That is about the perfect light density for my taste, similar to what I had in my video for the shorter trees.
