Is this led any good?

I am checking into getting a led for a possible veg light I don't know a lot about them but this one has 5 watt led and uses 450 actual watts the link to it is here does anyone know of a good light that will give me similar results as a 1000 hid would. http://www.dhgate.com/product/2014-best-mar-ii-series-5w-chip-led-grow/178692899.html#s1-7-1|2121081798

400 watts of actual dissipation, that will veg for sure. It is packed into a small footprint though. Would be much more useful to have those watts spread out and closer to the canopy.

agree, its a lot of Watt put in to one unit, and I bet its not all quality parts inside, I could easily find better quality out there for about the same money, on less watt but Im sure they do just as well, using less power and maybe have less chance to break down with a much better warranty if they did

also notice they measure in Lumens and Lux, find a LED seller that use Umol and Par to measure there lights

thanks for the info guys

np.

if you don't want to build it yourself and just want to buy a panel ready for use I would look in to Hans panels or Area-51

both have different setting for Veg and bloom

if you just want to Veg with em and don't want to trow to much $ at em I would look in to some DIY LEDs even the normal household LEDs can be used

can get em with 3 or four 3W LEDs (guess they run at about 6-8 true watt) a few of them in 5000K could easily Veg a plant

Somebody on here mentioned the other day that people tend to shop for watts, which is a bad mistake. I agree. Wattage is a measure of work. Wattage is NOT A MEASURE OF ILLUMINATION. Motors are usually rated in horsepower, but they can also be rated in watts. What, you say? That's right, google horsepower to watts conversion. One HP = 746 watts.

A device's rating in watts only tells you how hard the device is going to spin your meter. That's it. If people want to believe that the CannonFodder 2000 is better than the HappyHappy Tiger 1900 because it uses more watts, then that's how the sellers will pitch them.

I'd like to point out one thing in the marketing for that dhgate "2014 best Mar II" light. Well, two things. Right at the top - 900W. Holy cow, that's gotta be one serious light. Where's my credit card. Oh, no, wait, it's really 445W +/- at 110V.

Scroll down a little. They claim a lumen output. Lumens are a measure of light as perceived by humans, not plants, but it's more useful than wattage. 24,300 lumens. 24,300 lumens divided by 445 W = 55 lumens/watt. That's pretty darn uninspiring. 55 lumens/watt is CFL territory. Any off-the-shelf Home Depot LED does better than that.

Of course, who knows if the light actually puts out 24,300 lumens. I'm giving them the benefit of the doubt.

They're put out by lg-led solutions out of china, I've got one of their 600 watt reflector panels and I'm pretty happy with it so far. It does good in vegging and so far it's doing good with flowering. Their website is www.topledgrowlight.com and they've got a warehouse in new jersey so shipping's not too bad time wise. As Mellodrama pointed out allot of led panels only run at 50-60% of their advertised wattage and watts doesn't mean everything. Some companies will stretch the truth on what their products can do but I'm happy with the one I've got and am actually considering getting a couple of their mars II panels when I build a new flower room just to test 'em out

I study electronics and have alot of tools/help available what's this about constructing my own led light, is it worth the trouble?

Yes definitely worth the trouble. You get 25% increase in efficiency for about half the price.

I wish I could give you my input, but I'm trying out my first LED grow so I can't give any useful info other than that it rocks in veg so far
