LED true wattage misleading

[Sugarleaf]

Its seems the best measure of true light strength and intensity with led lights without getting into par and lumen specifics is how many watts the led pulls from the wall v.s. what's advertise or marketed. Is this a safe assumption?

For instance my mars hydro eco 300w pulls 110w from the wall. Then its safe to assume that im getting at least 110w output, no less to my grow space, which is nearly 1/3 of what's advertised.

They base the lighting off diodes.

Say 3watt diodes, and there are 5 of them, they will advertise as 15watt light, when in reality they only draw 5 watts from the wall.

The diodes are "equil to" x watts.

If you look at cfls at the store, it is the same idea. 5watt light replaces a 70watt.

With leds always look at actual draw unless you have a par meter

So far I have only seen one company advertise the true wattage with leds. Its CGE (running a light of theirs now).

I dont know about QB etc as I have no experience with them yet.

Correct me if I'm wrong Honest, I've also read that the 3 watt diodes are optimum, and that despite this (whether 3 watt or 5 or 10) the intensity in PAR will depend on "how hot" these diodes are wired, and that in terms of efficiency the 10 watt double chips are the least efficient. I recently ran across a light I hadn't previously come across whose PAR values were double what is common for their draw--when I read the negative comments at Amazon some users said the lights were actually weaker in use than comparable draw lights. One article I read said they'd never buy a light that didn't list PAR, and I found it curious that the Platinum line doesn't. I've also seen false comparisons with "equivalent HID replacement" in watts even in our own light--Amazon and other reviews all had it compared with a 600 watt HID when the company's own website expressed it as a 400 watt equivalent. Just bizarre. Guess we're lucky to hope that even a company's published numbers are accurate?

I don't know about today but it used to be that 100watt led meant it was equivalent to 100 watt incandescent bulb. Basically that "measure" started with cfl and halogens. Think that's bad, look at how companies determine wattage in music amplifiers.

Truth in advertising, does not exist. Fake news, fake advertising, it's all a bunch of shit. Someone please pass me my pipe

We all are aware of misleading led labels but some of us have really found that they do grow some weed very well.
I replaced my 400w hps with a cheapo "600w" led , draw is actually 125w....but my next grow revealed how impressive even cheap leds are so I bought another 600w led.
So even though I'm drawing only 250w for two leds, in results, I've far surpassed what a 400w used to do.

Very promising Automan. I'm definitely encouraged for our first grow, and our space is so small that I scarcely gave it a second thought. Though I was a lil disappointed when I came across 1 strain that explicitly recommended 1k lights to maximize its potential.

Hps rule of thumb is 50w per sq foot, good led can run between 25w and 30w per sq foot (wall draw) with roughly the same results.

When I switched over this issue finally drove me to DIY.

If someone says to me its "just like".... I get real suspicious.

We're at 50w/sq ft with a decent enuf blurple I guess. I liked the middle spectrum size and included UV/IR. Learning a lot here since. DIY-ers w/ electronics always impress the hell outa me. In a year I'll know better and tech will have improved even more, but 1 thing that won't change is our grow area unless we find a cheap farm and law keeps pace. But 4 sq ft is what we're tryin to maximize. Should be germinating in a week and I'm as uneasy as an expectant father.

All led when you buy, do not think that his name is watts, like we will put the actual watts on the site, some sellers may not. Now there are a lot of sellers on ebay who say their lights are 1,000 watts, but they're only 100 watts.The name of the product is sometimes for SEO, in fact, the wattof each lamp bead is 5w, or 3w, but when you use it, the actual output of the lamp bead is only about 30%. But it also makes the beads last longer
