how many 2.5 amp led lights will this unit drive??

I(A) = P(W) / V(V)orWatts = Amps * Volts30 watts = 2.5 amps * 12 voltsThe power supply is rated at 30 watts, and the voltage is 12 volts, which comes out to 2.5 amps. So the answer is one 2.5 amp string per power-supply.

I have 200 I think, and it does fine. You have to solder or electrical tape it though.

Be sure about how much load your LED lights take. A 2.5A LED light would be huge. Most BR30 bulbs are in the 10W ballpark @ 120VAC, which means < 90mA load. An under-cabinet puck LED light I'm looking at buying is 2W @ 12VDC, which would be 160mA - nowhere close to 2.5. A 12V LED @ 2.5A would be a 30W light.

How could it be 2 amps at 12v - that would be 24 watts of power consumption. Say we have 1.7fv at 60ma on each of the 48 LEDs. With resistors (as opposed to a CC power supply) this would consume about 420 mA. How do you get to 2amps?

That's what this is used for...outdoor lighting. And, I am not an electrician, but I think a 15 amp unit will support around 1500 watts of lighting needs.

3 double A's and i have had NO.....NO... problems with it .... yet the LED lights sue minimal power

The halogen bulb receptacle will accept the LED unit. The question is whether you have enough space to accommodate the other parts, ie. the LED device has a small fan that screws into the back of the LED lamp. you also need space for the ballast. The difference in brilliance is worth the effort. I don't know the amperage but I suspect that it's considerably lower

Yes! It really depends on how many lights you install. One or two would be fine.

Don't know. I have 1 controlling LEDs around my RV. Its outside and has worked well so far.

I checked the box that my lights came in and it says 1.9A @ 12v, 0.8A @ 24v. It seems like when I installed them I checked the current draw and it was about 1.0A but can't remember for sure. However, using 27 watts and 12 volts it calculates out to 2.25 amps. I know mine are not drawing near that much.

You should use good gauge wire and a relay they pull a lot of amps .if you can afford to get the led light bar they are brighter and wide angle and spotlight in one light.

It would depend on the voltage, the lights are 27 watts so in a 12 volt system they would draw about 2 amps.

I have 2 amps connected to mine and it works pretty good. my lights stopped flickering.

The unit is 240 Watts. If you are using 12 volts DC for the lights then you will need 20 amps to operate. The formula to figure out the amps is Watts divided by the Voltage.Your remote controller can only handle 6 amps. To bypass this, use a 50 amps 12 volts relay. Switch the relay with the remote and wire the LED bar through the relay from the battery. Make sure you fuse this installation.

The system is designed for the 2- 55watt lights that come with the kit only!!!

Hi Zac - I havent actually tired this, but here's the issue - USB power requirements can be variable amperage. It is very rare to see a USB device which needs over 500mA (1/2 amp), in which case if all 4 of your lights are within this spec (as almost ALL USB lights are) you will be fine - all 4 will be bright. However I do know of some USB lamps which draw 850mA, in which case you could plug only 2 of those in. If they are the usual USB lights I'd not worry, should work fine. Let us know!

Yea, just use a single throw 10 amp DC switch (there some that Amazon sells) which will allow you the ability to add more lights if needed.

HI Stew. I used 200ohms to drive 4 RGB leds in parallel with source of 9volts. All four connected to same resistor. I haven't measure current or voltages but they bright pretty good. let me know if you need any measure.

Hi More than enough if I counted my fingers correctly (ha ha) those two should draw less than 5 amps together(4.7 amps) this power supply will more than run the lights. You picked a good choice! I have one, love it!Oh! I almost forgot make sure you are using #14 gauge multi strand wire with an inline fuse holder with a 5 amp fuse it it blows go to 7 amp fuse.
