12 or 24V ~ LED strip lighting

[CNX69]

I need to install 22m continuous strip ( 60/LED per meter strip) +  Transformer/Driver( = ?Amps per meter)

 

Dealer recommends 24V and I65 LED. It will be interior install and i do not think i need water resistant LED. 

 

Thank you in advance

Is that the question ?

if so  then I think you are correct you don't need waterproof LED's ????

IP65 would also give better mechanical protection, the bare LED strips are easily damaged (think cleaning operations).

It depends on the location of the strips, most of mine are in ceiling lighting so no chance of them being touched.

20mA per led on 12 volt.

With 60 leds every meter, only one color, that's 60x20=1200mA=1.2Amp

22meter = 22 x 1.2 = 26.4 Amp.

 

For RGB, multiply with 3 and RGBW multiply with 4.

 

On 24 volt, divide current by 2.

24 volts the current can travel far more then on 12 volt without issues, as it is the half of that on 12volt.

 

But either way, it's suggested to have taps each 5 - 10 meters with a separate wires feeding DC to them.

Otherwise the first meter would carry all current for the whole string. and at 26 Amp, that's a lot.

 

To be uniform compatible with available supplies and strings, I'd go for 12 volt system.

Depending on the kind of ledstrip you want to get.

 

   

The one in the reel is a thin flexible pcb led strip and the other has two thicker wires run trough.

The first one definitely need taps each 5 meters while the latter can run for several meters, even up to 50m, without the need for taps/DC-injects.

The problem with a lot of the waterproof strips is the silicone/rubber compound used to encase the LEDs turns an ugly yellow, sometimes in just a few weeks. The quality of the light output therefore degrades very quickly. Amber/brown lighting is not pleasant.
