Reddit mentions of LEDENET Super Bright LED RGBW Strip Lights 5050 12V 5M 300LEDs RGB White Flexible Lighting

I am using FLS-PP with this strip - http://www.amazon.com/gp/product/B00HBMN4YO?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s01

I also have the new Philips Hue Strip.

Besides being cheaper when you have lengths of 5m or so, the FLS-PP with this light strip produces much better bright colors. It is hard to describe, but while Philips Hue strip produces nice deep dark colors, it's brighter colors look washed out compared to the custom setup.

There is another slight minus of Philips Hue Strip, it's power adapter is producing a slight noise. Something you will never notice in a living room, but might be annoying if you will place it in the bedroom.

I have about 4 different locations with these LED strip lighting. I use Cat 6 cable to do the runs. For example many of my LED strips are RGBW so you need 5 wires to make them work. Well cat 6 or even 5 as you know has 8 wires nice solid core stuff that is easy to solder. I've even contemplated using a patch panel as a DC distribution point and using RJ connector but have not done that yet since I'm pretty much done adding LEDs. BTW old desktop power supplies make great 12 volt power sources. As a controllers I use this with my Veralite system.

I'd run some 12 volt tot he kitchen for sure for under cabinet lights. Stair ways are also a nice touch

This is dimmable LED tape

First, even though those are listed as waterproof, it is IP65 and it says not to soak/submerge in water. Not sure what your plans are there.

That aside, I think the general guidance is that these strips are limited to about 10-15m (2-3 strips) of length before the voltage drop is too much since the conductors in each strip is very tiny. If you are intending to run 30 m long, you may need to use separate 10m lengths with thicker conductor supplies running with the strip.

I recommend you ask the seller what the rating is for max number of strips that can be put into a single run. I would also ask what the wattage per 5m strip is for the RGBW. That will tell you if your power supply will have enough. I couldn't find it in the listing.

My bigger concern would be that a long parallel run at 50A might be a very hot cable and those strips may not be able to handle it (don't know the actual current draw because we don't know per strip max wattage). You might want to do a parallel/series arrangement to bump the voltage to 24V or 36V so you can cut the current by half or two thirds and use smaller conductors. There are similar power supplies in 24V/25A/600W and 36V/16A/600W configurations on amazon if you search.

​

For example, this similar strip of RGBW on amazon (not waterproof tho):

https://www.amazon.com/LEDENET-Bright-Flexible-Lights-Lighting/dp/B00HBMN4YO

Says per 5m roll: 5A draw, 12VDC, 60W per 5m

The question/answer section says no more than 2 strips in parallel long run.

If you were to take this example and just connect 6 strips, 30A total at 12VDC for a total of 360W. 30A seems like a lot of current. You would need 7 AWG cable to carry that which is 3.6mm thick (conductor without sheath). If you were making a tight array in a square light panel, you could get away with chassis current rating of 14 AWG but that is still pretty thick.

​

EDIT: If you already bought some of these strips and have them. You could use a bench power supply to find out exactly how much current each strip draws when 12VDC is supplied them.

Here's some of what I was looking to add to my case eventually.

NZXT Hue

LEDENET RGBW Strips

SuperNight RGBW Strips

Phanteks RGB Strips

1-2 RGBW Splitter

If your mobo doesn't have an rgb(w) header, the nzxt hue+ would be a good option. I believe there's CAM software to control the lighting, opposed to a physical controller which you would have to route outside your case or open it up to change anything.

If you do have a mobo header for LEDs, check if its RGB or RGBW, then grab what's needed. I believe the splitter would allow you to run two off of it (I was gonna do one inside my case and route one outside the case around the desk.)

Out of curiosity, because I'm looking for a cheap alternative too... Why did you suggest the AliExpress over Amazon ones such as this:

Also, do you need to purchase a power supply with either led product?

Thanks!
