Using an A/C adapter to light the 20 LEDs, how much WATTAGE would be used? Thank you.

Hi Muffin, The 4.5V AC Adaptor is not included, but when purchased provides electrical current versus a battery charge. Here's a WikiHow article - with pictures - about converting electrical appliances to run on alternate current applications including a wattage conversion discussion. Hope this helps. BTW, I love this lantern. Solid construction, bright and priced right. http://www.wikihow.com/Make-Battery-EliminatorsBest - Melanie

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.

The best information I can find is the LED string is about 1.5 Watts/ft.(4.8 W/m) So if you add 125 ft. it will use 180 watts. Looks like you will need a larger power supply or break your lights up into multiple circuits with smaller power supplies. 60 Watts will only carry about 40 ft. of LEDs.

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?

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.

I am using mine to run a 24 watts LED strip. The power supply is rating 60 watts, but is not a good idea to run any power supply to the maximum capacity.

"Wattage" is normally shown as "Max" wattage when in operation. If this product is listed as .8 watts (120vac x .067ma) then the "idle" current should be significantly less, probably about .020 amps/20ma or 120*.02= 2.4 watts. It could easily be less, depending on the circuit design. When the lights are not on, the unit is 1)determining if it is light or dark (dusk to dawn sensing) and 2)if there is "motion" in the vicinity. The energy used during this "idle" process is extremely low.

From my understanding 7.2 watts per ten modules. 20 sets of ten modules is 200 modules. Which mathematically needs 144 watts. I'm not an electrician but you might lose some brightness if you plan to string them all together. I've read about an amp you can wire in after so many strings but can no longer find that literature. -I'm not an electrician but hope that helps.

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.

You are dealing with two 27 watt lights and using a power supply rated at 12 amps. Be sure to check amount of amps to run the two lights. Theoretically it should work.

each 21 LED strip takes 1.5 watts and the typical power supply used (12 Volts at 1 amp) is 12 watts so the absolute maximum is 8 but I would not use more than 6 staying at 80% of the power supply rating. It typically looks like the supplier uses between 3 and 5.

I believe it's about 600-650w equivalent. Not sure about how many individual leds are actually there.

not sure I understand your question, if this is pertaining to the 48 it LEDs, it can take up to 1 amp @ 12volts.

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!

The LED lights operate on A/C voltage between 85v and 264v. The low voltage system output is probably only 12v to 25v so these would not work. Some low volt systems may also operate on DC

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.

20 x 10w = 200w, the LET151 only puts out 150w. Either use 2 w/ 10 lamps each, or find a 200+ watt transformer.
