I have a 30-watt LED floodlight that I wan't to run with a 12-volt 2.5-amp 30-watt power supply, but the LED runs on 24-30 volts.Will this board work?

Yes. If your LED is 30W and runs on 24-30V then it draws 1.33-1.0 amps respectively. The converter can output 3A continuously and the requirement on voltage is that the maximum ratio of output voltage to input voltage is 3. So since you're putting 12V in, you can get 24 or 30V out easily, and this still keeps you under the current limit. Hope this helps, the converter has been good for me, it's very stable on the output despite a changing input. If I can be anymore help let me know. -Brian

Yes. Although you may want to overestimate your requirements for that power supply. These boards are quite efficient, but not 100%, so your supply will need to provide &gt;30 watts to get 30 watts to the LED. Anyway, in all cases it is a good idea to have 30% or so overhead on your power supply.

I'm not sure but it seems to me that if you split the 240 v line into two 120 v lines you could use one of these lines to power the floodlight.

Look up the 12 volt 48watt power supply that's the one I use with mine it's also prett sweet to have the led dimmer I believe led wholesalers is who I bought from through amazon

Yes. I have done exactly that by replacing the two flood light fixtures (on a standard motion sensor light kit) with two of these LEDs. It works perfectly. Just pay Attention to the wiring!! and do one side at a time. :)When motion sensors trigger they simply send 120v (in USA) to the existing flood light sockets so that the bulbs light up.These particular LEDs can handle anywhere from 80v all the way up to 240v if I recall correctly.So make sure you hook them up on the two wires going directly to the old socket connectors and you will be fine.

yes, it should work fine,Leds are very low amperage, you might have to use a resister to limit voltage depending on the LED Rating.

Short ans. NO The literature says it draws 18 amps at 12v. That works out to just over 200 watts or less than power to supply a 300 watt light bulb. The 2 amps is way to small a capacity

Should run lights with no problem... 25A is about the equivalent to a power point...

I don't know. You'd have to do the math w/ the watts and amps this power supply supplies. My advice would be to find the needs of your light strip and then search based on those specs. That's how I found this wall wart for my wall clock.

LED's come in all different voltage ranges , most commons being 1.5 volts, 3 volts, 9 volts, and 12 volts. The output from the LED driver: *Input Voltage:110 -130 Volt*Output Voltage:12V DC*Power:150 Watt 12.5Awould imply that you are within the working range of the LED driver in that you are not exceeding 150 watts. Watts = volt amps, therefore amps = 60/12 = 5 amps. LED driver is limited by 12.5 amps, therefore you ar within the working range. Don't see a problem with your planned setup.

My lamp, shipped 7-2012, uses 3.24W, 270ma @ 12VDC. You have brought up my only complaint with this item. Because these SMDs are wired as 12 sets of 3 chips in parallel, and each chip should be driven at 20ma max, optimally this board should be configured to draw 240ma, which it does at 11.75VDC. At 12VDC each chip draws 22ma, or 10% over its design specification. Since autos often supply 14V, in some applications the 'bulb' will run hot and not last as long as it should.

Yes. You'll be fine. Max amps are 20 for this controller. With optimal lighting your panels may never even actually reach 3x 5.57 amps. Also, since this controller will charge 24 volts, you can actually run twice the panels at double voltage and still keep amps under 20. Read the manual!

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.

Ouse standard 4w 12v bulbs. However I would think any led that had the correct base and rated for 12 v yes would work. Not much help.

I expect it will work, but won't be as bright as the 18v transformer. The bulbs are rated at 14 volts and they are in series so in theory the fixture could handle twice your 12v source.

About any of the led strip supplies will work for this / these. I use the ones that look like PC lap top supplies. Lighting EVER® Power Adaptor, Transformers, Power Supply For LED Strip, 12V, 3A Max, 36 Watt Max . These are about $10.00 each. You will need about 30watts (<3 Amps) per strip. I have found the supplied controller will drive at least 2 strips pretty well. It is recommended not to use more than 2 strips in series (one plugged into the next.

This is 150 watts and don't know if that is the same as you are needing. It is a medium base that fits all flood lights.

Yes, you can use this for anything that requires a 12 volt input, just keep in mind you want to keep the load at or less than 75% of maximum. Although mine has been operating just fine powering my led controller and 150 watts of strip lights
