Septon Posted August 31, 2017 Share Posted August 31, 2017 Hello, I am very new to RBG. I wanted to buy 2 RBG CMB24D is a 24 channel Direct Current Controller while on sale here today. BUT, I can't find the ribbons. So I found someone selling them and want to ensure i am not an idiot. I want to run 16 ribbons. RGB Color - IP65 White PCB - 5M 5050 DC12V 60LEDs/m 5m/lot With the cards can I use my 12V 30A 360W Power supplies I have here? One for each card? Can Someone respond back today perhaps? Thank you.

Mr. P Posted August 31, 2017 Share Posted August 31, 2017 I would need the specs or a link for the ribbons but I am guessing that they are probably 72 watts per strip since they are 60 LEDs/m. Eight ribbons at 72 watts would be 576w total so your power supply would be too small. I would highly recommend that you look for the 30 LEDs/m as they are usually around 36w per strip and you current PS would be fine. Link to comment Share on other sites More sharing options...

TheDucks Posted August 31, 2017 Share Posted August 31, 2017 you used the plural form: Power supplies You have 2 or 4 Each CMB can have 2 power feeds (1 per 4 out RGB bank/8 outputs) Do NOT join the Plus sides if you use 2 supplies, but DO with the negative (I think the CMB does that for you, but mine is mounted, so I can't verify) Link to comment Share on other sites More sharing options...
Septon Posted August 31, 2017 Author Share Posted August 31, 2017 How about 12v 50a 600watt? Would that do it do you think? Also, what would be the difference between 30/60, I figured the 60 would be better? Link to comment Share on other sites More sharing options...

I have a few power supplied, I have a couple of 12v 15a 180w I have a couple of 12v 30 360 Link to comment Share on other sites More sharing options...

Here are similar strips that I am only posting as a reference for detailed specs as they are very similar. http://www.diyledexpress.com/index.php?main_page=product_info&cPath=10&products_id=51 I run three CMB24's but I use the 30 LEDs/m on all of them. 1 minute ago, Septon said: How about 12v 50a 600watt?

Also, what would be the difference between 30/60, I figured the 60 would be better? 60 is not always better as many times they can be too bright even with 30 and the intensity will have to be turned down.

The price difference is not that much between them, see my example here at AliExpress.

Me personally, I will only use the 30 as they are plenty bright enough and for many of my sequences I have to turn the intensity down to 50%.

Hmmm then perhaps I should go 30 If I do, you think those power supplies I have should do, and if not I need 600w right? Link to comment Share on other sites More sharing options...

If you go with the 30 then the PS you have will be fine and you will only need one per board. 1 Link to comment Share on other sites More sharing options...

Next quesiton, I want to do a 40' stretch, I realize i need a power booster. RGB Amplifier Controller 12A For 3528 5050 RGB LED Strip Light DC12-24V I found that think it would work? Worst case i don't make it 40' but I know I need a boost. (and truly, thank you for your help here...) Link to comment Share on other sites More sharing options...
Mr. P Posted August 31, 2017 Share Posted August 31, 2017 If you are tallking from the board to the light string is 40' then that is no problem for 12v dumb RGB even without the booster. I have a run that is 75' with no problems. Link to comment Share on other sites More sharing options...
Septon Posted August 31, 2017 Author Share Posted August 31, 2017 Man that is great! One Last thing. I plan on putting my CMD Gigger on the deck. But have to go up 20' I plan on Just using 4 Pin RBG + Wire such as this. Is that a problem to use this as a power run? 2m/5m/10M 2pin wire 3pin wire 4Pin 5pin Extension wire,22 awg wire, RGB+White Wire Connector Cable For 3528 5050 LED Strip Link to comment Share on other sites More sharing options...

For the longer runs you want to go with a thicker wire, 18awg minimum as the issue with the longer runs is the voltage drop due to resistance in the wire. Thicker wire such as 18awg or better would mean less voltage drop over the longer span. Link to comment Share on other sites More sharing options...

Not a good plan to operate at 100%, so two 360 watt supplies would be better. Easy to hook up two supplies to the CMB24D too. The other thing to keep in mind is the total power limit of the CMB24D. 16 strips at 72 watts each would exceed the limit for the board. 1 hour ago, Septon said: Also, what would be the difference between 30/60, I figured the 60 would be better? The 60 pixel per meter strips are BRIGHT - REALLY BRIGHT! For most applications, 30 per meter is more than enough. That also solves the power limit of teh CMB24D issue I mentioned above. 1 hour ago, TheDucks said: Do NOT join the Plus sides if you use 2 supplies, but DO with the negative (I think the CMB does that for you, but mine is mounted, so I can't verify) TheDucks is right about the CMB24D.

Septon Posted August 31, 2017 Author Share Posted August 31, 2017 Hey One more question... I want to tape these lights to my house for year round. Any suggestion on the best tape? My pitch on my roof is really high! Link to comment Share on other sites More sharing options...
Mr. P Posted August 31, 2017 Share Posted August 31, 2017 Nope, sorry, I don't use tape. Mine are mounted year round but they are mounted on 1/2 inch pvc and clipped on. Link to comment Share on other sites More sharing options...

My pitch on my roof is really high! I don't think tape would be good. I use a lot of both smart and dumb strips for my year round landscape lighting, so they are left up year round. In all of my cases, the strips are attached to brick. I use GE Silicon II to glue the strips in place. Makes for a very low profile installation. Mr. P's suggestions would be good if you want to be able to remove them, but would be more visible..
