How much power of the converter consume? I want make LED camping light adjustable but meanwhile don't want waste too much energy.

It's a buck converter, so it's just about the most efficient voltage regulator money can buy. Whereas a linear regulator works by being 'partially on', and wasting all the unwanted power as heat, a buck converter works by switching between completely on and completely off, hardly wasting any energy at all. The actual regulatory component, the LM2596, has an efficiency that ranges from 70-95% depending on input voltage, output voltage, and current load. You can see the efficiency curves for a full 3A load on figure 5 of its datasheet: http://www.ti.com/lit/ds/symlink/lm2596.pdf You'll also have very small power losses from the inductor and resistors, and the capacitors will need to be charged each time you turn it on, but those losses are not significant in most applications. I've used this device to step down from 12V to 5V at 1A, which would make a linear regulator boiling hot, but this regulator just gets mildly warm

I will vary depending upon the current load and the voltage out. one of mine is hooked to a 6 volt lantern battery and has been driving a led strip of 25 led's for over 10 weeks now and the battery voltage has only dropped .3 volts. I hope this helps.

No! My wife and I live in a small 1600 square foot home. We use all LED and CFL lightning and have just bought all energy efficient appliances. We have 2100 watts of solar (We can upgrade to 3100 watts on our system) and can supply 70 percent of our energy needs daily. We have 8 145 watt panels and 4 245 watt panels along with 5 kilowatts of pure sign inverters and 20 kilowatts of batteries. Hope this helps to answer your question.

If your camp is large or small you will need to know how many amp hours that it requires to fulfill it's needs. I currently utilize two slr125's to power my small homestead. I can run this energystar notebook computer all night long. I can also run a couple of 12 volt dc lights all night at the same time. If you require much more than that I recommend doing some research into how much power you need and how much you are willing to spend. Watts equal amps times volts. If you are wanting to run AC appliances you will need an inverter. my laptop-60 watts 2 light bulbs-30 watts 90 watts divided by 12 volts equals 7.5 amps. To run my computer and two lights for a ten hour night it takes seventy five amp hours. Also take into consideration that deep cycle, lead acid, AGM batteries are very sensitive to cold weather and should never be exposed to freezing temperatures unless fully charged. As a rule of thumb always double what you need. Those winter months can be long. Have fun camping!

I run #10 wire to a Power/Charge converter and connect that to charge my 12volt batteries (in series or parallel). To the 12 volt batteries I connect a 400 Watt or greater Power Inverter, one with both 110v AND 12 volt outlets. I use the batteries to run my camping trailer so most of my power is used there. But from the Power Inverter I can run an outside TV, Sirius radio, small fan and all kinds of neat stuff. As long as I keep my eyes on it I can go weeks on two batteries and one 100w solar panel (in camping/travel trailer)

Don't know Paul. But ran about 50 watts (fan and light bulb) for 5 hours off the converter. Best, Ron S.

I don't know - I only bought some - I think it burns about 18 watts but gives LOT of light - gotta cut down on the electricity bill.

Someone had left feedback about this. They said... I measured the current to the system and it was 1.25 A on hi, and 110 mA when dimmed which figures to 16 and 1.4 watts. By contrast my two dome light bulbs draw 680 mA each or 17 watts for the pair, more than the DRLs on hi.

I bought the very same setup but had not hooked it up till I saw your question. My 12 volt power supply is only good to 5 amps but the converter boosted the voltage up to 33 volts no problem and the light is blinding at 60+ watts. I didn't have a heat sink on the 100 watt LED so I could only run it a few seconds. THe buck converter has some good heat sinks on it, your biggest issue will be to cool the LED. I have used a CPU cooling fan and run my other 100 watt LED as an adjustable lab bench light maxing out at a de-rated 30 Watts, it works amazingly well. You might want to put a small fan on the boost converter as well since 10 watts of dissipated power does add up. I bought the very same setup but had not hooked it up till I saw your question.

Even if it were actually "lit" by LED, the amount of power used by a single, tiny LED is NOT enough to drain the batteries in any measurable period of time. We're talking at most, a few milliwatts (thousandths of a watt).

From the spec sheet. Voltage: 12-30 DC. To keep 10 watts, if you lower the voltage it increases the current through the electronics to run the LED

I'm not sure what you are asking. The LC2400 unit is rated for 2400 Watts (20A) total draw when plugged into a 20A dedicated circuit. I do not know how much power it draws on it's own just plugged into an outlet or how much it adds to the total power consumption; it does have some electronics to monitor the incoming power, but I would imagine it consumes very little on its own. You should contact Tripp Lite directly if you are looking for more specific information.

Hi Nigel - You'll have to let me know how your solar panel / LED shed light project turns out. I've learned much and had fun with my 50W setup. Let me know how yours ends up. ~Bryan ;-)

I would say a lot more. A 40W equivalent LED bulb ranges from consuming anywhere from 5W - 7W. That's about 8x more consumed power.

You need a NinjaMcPowerConverter. But seriously....the simplest way is probably to get a cheap dc to ac converter from Northern Tool and just plug in the existing power supply. There are better ways, but not as simple, and I think you want simple. About 20 bucks gets the converter. It's cheap, and won't even turn a screw-gun, but it will power low-amp lights.

In general, yes but----. The Intermatic is a bulky expensive unit meant to power up 6 outdoor halogen lights for a total load of 120 watts at 12 volts. Although there is no spec on the power consumption of the LED string, it is probably a lot lower than 120 watts. The other issue is the means of connection; the Intermatic uses screw terminals but the LED string is unspecified and might be a problem to connect.

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?

I've read that you should only use a converter for up to half the rated power output, so anything up to 150 watt would be OK. So, I'd suggest you get a more powerful converter, e.g. 500 W.
