I’m looking to connect 8x 1m led strips which are at 400mA, 4.8W/m and 12V, I’m trying to connect these to a switch in the room what driver should I use?
I have just replaced a 50W halogen bulb with a 5W (35W equivalent) MR16 LED bulb. I have also replaced the driver with an Aurora AU-LED 16T constant voltage driver 12V 1-16W. The bulb strobes like a disco . Can anyone tell me what I have got wrong.
Kitchen fitters put led strips in our kitchen, and after 6 months, the lights went dim. Fitter has us used a 12v DC 30w LED Converter 2.5A, 100-240v AC. Is this led transformer the correct specification do you think? It's a small to medium-sized kitchen and leds just run under wall units and inside a glass cupboard.
Let's first think about a constant voltage source, which is something with which you are more familiar. If the voltage source powers something, it will try to give whatever current is needed. How does it know how much current to give? It looks at its output voltage. If it's less than it should be, it gives more current, and if it's more than it should be, it gives less current. This is basically the definition of a constant voltage source. It does whatever it can to maintain a constant output voltage. The LED driver we're talking about here is a constant current source. It does whatever it can to maintain the specific current by adjusting the voltage. That's the definition of a constant current source: the current is constant and the voltage varies. An LED connected to a constant voltage source must have a resistor in series to limit the current. A 5v or 12v or 24v LED strip has tiny resistors among the LEDs. LEDs are more naturally driven by a constant current source. No resistors on the strip. It doesn't matter how long the wires are (no power injection needed).
Can we connect a 3 meter or 5 meter led strip (12 volts, 20 watt per meter , 240 led per meter ) to a 12 volt car battery directly without drivers , assume passive cooling is provided for led strip.
hello im a bit stuck on this ive got 23m flexi strip lights they run at 30w for every 5m … not sure of the mA ?? I need to connect all together … im sure I need a constant voltage they are a 12v output … can you recommend a driver for me please
Hi I have a question. I have 9 led downlights of 24w each with its driver. I wanted to know if I can replace the nine drivers that each one comes with and power them all with a single 300W driver.
Hi, it depends what output of your nine drivers, could you take them out and check, then I would know what parameter of the driver you can use to driver power 9 led downlights.
@@wenyingjiang504 Thanks for your interest in helping :) The driver specifications for each downlight say: LED DRIVER, MODEL: (19-24) X1W, PRI: AC85-265V 50 / 60Hz, SEC: 280mA ± 5%, OUTPUT LOAD: DC57-96V.

hello. if I have 6 cree leds 3w 3.3v I can use a 30w led driver 22-38v (constant current)? summarizing the voltage of the leds we have less than 22v. it can damage the leds?

Wow, I cut my 16ft LED strip into 2 halves as a portion near the incoming power supply from a 12V, 6A unit, changed from the blue to a yellowish color? Any idea why? The incoming Voltage drops from 12.32V (No Load) to 11.85V when the 8ft. Strip is on, and, the Voltage at the other end of the 8ft. Strip is 10.30V. Is this the norm as I presumed in a parallel circuit the Voltage remains constant? By the way every section where it says U can cut the strip has 3 LEDs.
1) changed from the blue to a yellowish color? Probably the voltage /current is too low. This can occur when dimming at extremely low levels 2) incoming Voltage drops from 12.32V - unloaded (no load) voltage is often higher, especially on cheap power supplies 3) other end of the 8ft. Strip is 10.30V - indicates a cheap strip as the copper buss carrying the power is too thin/narrow
The one bit of info I wanted was not covered. For the power supplies with variable voltage, how do you actually set the output voltage? Is there a knob? A screw? A selector switch? How does it work?
Kenn, what would happen if I used a 34v driver on a 36v LED ceiling light? They are the same brand and the plugs do fit each other. Would it be dangerous or just slightly dimmer than it should be?
