how many amps does this 300w led pull?
875756
I measured 1.46 amps at 120v, so 175.2 watts total... hardly 300 if I understand simple comparisons.

I haven't measured it with a meter but the literature says it uses 170 watts. If that is accurate it equates to 1.41 Amperes.

probably around two two or three. My LED had a sticker that told me how many... I don't have the 300 though.

Hello,it use the High Quality brightest 5050 SMD LEDs,The actual luminous flux about 320-350Lumens at 12v ~30v ,thanks!

The 240watt designation is for the 80 units of 3watt diodes that go into the light. Actual power draw is always less and varies between 1.8-2.5 wattss per diode so the actual power draw for this light is around 150 watts. Besides power draw what is important is the technology that goes into the spectral ratio and this light is made with G8LED Optimal 8-band technology. Any light at 35watts is not comparable to this LED grow light.

(5-smd led lamp / .05 amp x 12volt = .6 watt) ( old incandescent bulb / .25 amp x 12 volt = 3 watts ) The led bulbs look to be as bright as the incandescent bulbs but it is a white light (led) not yellow (incandescent)

This is a delayed contact closure, not a power supply. You have to supply power for it to work.From the picture it can handle upto 10A. Your led only draws 2A.

Dear Mstruyf , Nice day. Thanks for your interest on this item. This is Lydia from customer service team, it's my pleasure to help you. So you mean the size or the watt of the LED? If for the watt of the LED, 250W or 400W is much better. Thanks for your time and best regards! Lydia

Here is a link to the most extensive testing I've seen with these lights (although the link is discussing the 300 LED version, so you'll want to do your own calculations based on these numbers.) Basically the spec sheet states .24 watts per LED. Of course you'll have to take into account the voltage drop, and with 20M of them you'll definitely want to look into dual-feeding to keep consistent brightness/color value... but all of that is explained in the link below much better than I can do here. Hope that helps! http://electronics.stackexchange.com/questions/19413/why-doesnt-my-5050-led-strip-draw-as-much-power-as-i-expect

In places where we still have incandescent bulbs (1141s) - the amp draw measures ~2 when on. These LEDs, by contrast, do not draw enough to even get a reading at all on my equipment. Really - almost nothing.

This is a 30 Watt supply. It is fine for one 16 foot 3528 LED strip (typically consumes about 16W) I have also found that it is OK for one 16 foot 5500 LED strip (typically consumes about 22 Watt). This supply will not run even one 16 foot, high-power LED strip. (I have found that 5630 LED strip (16 foot) can consume as much as 42 Watts - The 5630 LED strip definitely overloads this supply)

LED'S draw much less current than a standard incandescent bulb. That's why they hyper flash when you install them without resistors. LED watts are measured in milli-watts. It depends on the LED lamp you buy. If it is a 1W lamp, then divide it with the number of diodes. These LED bulbs are probably no more than 2W or 3W bulbs. Hope this helps!

Don't know amp draw they are led so it's pretty close to 5 to 10 amps per light they throw a beam about twenty feet behind the boat I only have two lights I think the package said that they are 600 plus lumens

300 Watt or greater power supply with a minimum of 18 Amp on the +12 volt rail

I'd say that was close. I used 1 roll to make 5 light fixtures (for my motorhome), and they each draw just under 1 amp. 6 rolls would get you pretty close to 30 amps.

I believe 200. We put 4 of these on the sign at the entrance of our subdivision, powered by solar charged battery system. They draw only .25 amps each at 12 vdc and fully illuminate our sign

I didn't see actual specs on the light confirming the information, but a quick count would say about 300 leds and approximately 600w of lighting. It has a variable brightness knob on the back. I have used it with a battery pack and the power supply. It seems brighter with the power supply. Hope the info helps!

Manufacturer's rating is 300W / 2.5A maximum load. It is *NOT* for high current applications. I use it for controlling exterior lights on a detached garage. Look here: http://ecx.images-amazon.com/images/I/91WEInllQDS.pdf

I am using 300watt equivalent LED bulb but it actually only use 40 watt energy.
