What is the ACTUAL power draw? I know they don't run these LED's at 100%, so 45 - 3 watt led chips does not equal 145 watts

I have taken this one apart and it had a 90 watt power supply. I have since moved on to better built lights and I am not a fan of these Blackstar units. Just fyi 45x3 is 135 not 145. Leds are not efficient being run at 100% of their wattage rating.

mine was super bright almost blinding but i got rid of it cuz i couldnt grow anything with it i went back to hps and mh as for the power draw mine was around 90 watts

You are correct that many LED lights are sadly lacking lumen specs. I don't nomally buy ones without lumen specs unless I don't have much choice for my application and then I cross my fingers or check a lot of reviews. High powered CREE LED's are more expensive than piling in a bunch of lower output cheap ones. Pick your price point and good luck finding lumen ratings.

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.

It's 30 watts. Watts is not a measure of light output but a measure of electrical consumption. LEDs are far more efficient vs incandescent. This LED light should work quite well for you as well as using 470 watts watts of electricity!

I don't know the answer, as I don't recall finding that info. I can tell you I've been running 8 LEDs and (5) 7 watt fixtures for about a year with no problems.

Its 3watts per chip at 100 chips is 300 watts i know i have been useing the light fot two plants and any closer then 18 inches will flat burn the the plants the lights work fantastic.they really only draw about 120 watts from the wall but the transformer in the lights puts 300 watts of power to the chips Powerful lights works for two plants.Hope this helps

The LED's will probably out live me! They get only slightly warm after running them for a while. They can run all night long no problem. Power efficient too!

It depends on how many LED strips you are working with. I have found these to only pull about 0.44 Amps for a 300 LED strip. You could have 10 strips tied together on one power supply and you would still only be pulling 4.4 Amps total. I have also found that when you tie full strips together you get a roll off on the tail end so the lights are not equally lit. You have to wire these parallel to avoid this issue, or that's what I found by working with these great new LED strips.

I am not sure wgich strip you are asking about. I bought the 300 led's and 600 led's. They are 24 watt and 46 watt. You need to use at least 2 amp for the 24 watt and 3.5 for the 46 watt. The formula to use if I remember it correctly is : Watts=volt X amp So, at 24 watt, you divide 24 watt by 12 volts and you get 2 amps Hope this helps

The manufacturer says, "The display card requires up to 225 watts of power". Most desktops with an i5 or i7 draw less that 100 watts. A 460 watt power supply is more than adequate. It seems people are always telling you that you need a humongous power supply but anyone that builds computers and/or uses them professionally like I do know this is just hype. I run two computers, a monitor, a 23" LED LCD HD TV, and a lot of other minor items behind an UPS and all of them seldom draw more than 300 watts combined. When playing a high GUI game the draw may go as high as 350 watt for everything. Fred Brooks owner and CEO, H&O PC Solutions

Their claims seem a bit off, it's more like 1200 to 1500 lumens. Elsewhere datasheets show 67 lumens per watt Epistar LEDs and current measurements show 23W INPUT, so you do the math subtracting for inefficiencies since output must be lower than input power. It's still a good lumen:price ratio but the actual lumen range is helpful to know for comparative purposes.

The answer provided below is incorrect. The LED is rated at 72W for 5 meter strip or 2Amps / Color. For RGB, you are looking at 6Amps at 12v or 72Watts. The included 60W power supply (12V @ 5A) is under powered for 1 strip and in appropriate for 3 strips. If you are using 5m RGB 5050 LEDs with 72W rating as what is described in this product, you would need 72W x 3 = 216W to adequately supply the necessary power to light up 3 strips that are 16' in length.

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

The 5 watts is about .4 amps or 400 milliamps. I have dimmer LED's in my RV and they run .2 amps. I'd rather use more of the less powerful bulbs, to get more even lighting.

Though I didn't actually measure the watts draw I would estimate they draw considerable less power than a normal bulb and puts out plenty of light and also very little heat. Led,s use so little power anyway, it's just a matter of just finding one that is a decent price while performing about as well as a standard incandescent bulb. Color, light output, price, and heat output, would be the most important things to look for.

no they lug into the card that fits the expantion slot and it uses at most about 10w led don't use much power but to be safe always have an extra 50 - 20 w of power extra for power jumps. 50 recommended 30 is the least i would feel safe with.

I was wondering the same thing and still am not 100% sure. But, from what I have read, each 5050 SMD produces 12-15 lumen per chip. This type of strip has 300 chips per 16.4 feet. Check my math, but this comes out to about 219 to 225 lumens per foot of strip. Its hard to find good info on LED strips. No one at Home Depot or Lowes seems very knowledgable. Here is the link where I got my info ... http://www.ledlightsworld.com/led-strips-flexible-led-strips-c-1_49.html
