Lefik Great guide!

Forgive me for being a little slow, but I had planned on running some 3528 @ 30 per metre from my cases in built fan controller (3-pin). So When I ramped up my fans speed, my LED's would also increase in brightness. From what you've said would that mean that the lower settings on my fan controller would not light up the LED's? My case is an NZXT Phantom 530, so it has a 3 stage fan controller (possibly 5v, 7v and 12v?).

Nice guide btw smile.gif

doyll Nice tutorial. thumb.gif

Just got 5m 5050 RGB kit with remote. Now need to get some 4x lead wire and start playing.. I mean building. biggrin.gif

Belial Comparison of LEDs:
NZXT White 1m LED:

3528m LED stripk not even aimed on the board.

On the NZXT led strip, the white light is kinda overriden by the blue glow from my fans, there is definitely a white light to it (like the 2nd image), but I think the 2nd image pretty clearly shows the strip is far worse then just some 3528. Literally just having like a 6" strip of 3528 on the top of your case is more lighting then an nzxt led strip set up optimally.

Belial Hm I'll edit to go more into it, but I thought I was clear on that. i describe the NZXT and Bitfenix kits, where they are good or not. The problem is that they really pale in comparison to 3528s.

Like you should never buy the bitfenix kit because of 3528. It's literally just a small piece of 3528 with an insane markup, there is absolutely no reason to get it. And then the NZXT kit is kinda okay.... but when you really get into it, 3528 is still better. Maybe the 2m kit.... I still have my nzxt kit hooked up but I'm probably going to toss it.

But for quick easy leds, sure, nzxt kit is what I'd recommend.

Noskcaj Maybe add a comparison or some recommended kits? nzxt, bitfenix, and icemodz are the companies i can think of.

Belial yeja you'd need a resistor, probably just work off the 5v line to drop it. I'm not sure what your purpose is though, what are you trying to do. I've never used a 2v led before.

They are 2v 20mA LEDs. The third photo has the resister info. Some sites have "12v" LEDs but seem to have the resistor built into the bulb somehow according to the diagrams and still output 20mA so I'm guessing they end up being roughly the same. But I could be reading or understanding it incorrectly.

Skuli Belial, perhaps you could add info on wiring individual LED's.

I've been researching them this past week and have ordered 30 "5mm Straw Hat Wide Angle Red LED - Ultra Bright" and a bunch of "510 ohm - 1/4 Watt Metal Film Resistors". I also got a 5m strip of 3528 LEDs as well. Based on what I could find on the website I need to include a 510 ohm resister for each LED when using a 12v power source. Prewired LEDs seem to have one included. I have a solderless breadboard and if all goes well, I'll just be soldering the resistors and wires to the LED's and "plugging" them into the breadboard which will be connected to my PSU.

I say "I'll be" above, but really my daughter will be doing the lighting. She has more recent experience soldering anyway. smile.gif

So, does it sound like I'm on the right path to you? I'm a complete noob when it comes to this stuff.
