Anyway, back to the subject at hand. It's just weed guys. Even gramma's are doing it. Not A big deal.

Most blurple growers don't know what their light is putting out. Maybe weed is just weed, but lights are not just lights. For instance, the Twilight blurple guy posted specs indicating 36 LPW. I have a 720 watt COB setup. It's almost 4 times as efficient as the Twilight lamps. I would need 3000w of Twilight lamps in my closet to get the same results I'm getting now. Over 5x as much heat and 4x the electricity for the lamps alone plus the extra expense of heat removal.

To replace the 200w Twilight lamp I could do it with a single 50w COB. It would cost half as much and use 75% less electricity.

While what you're saying is true (blurple users rarely know the specs of their lamps), lm/W really isn't a good way of rating a blurple lamp. The reason is because the LER of those 2 wavelengths are significantly lower than the LER of the cree 3000k 80cri SPD. An 80lm/W blurple lamp would be over 100% efficiency, which is clearly not possible.



This means that 1W of 555nm radiation will be 683lm/W while 1W of 660nm radation will be more like 42lm/W, and quickly tapering off as you leave the range of human vision. This means a 42lm/W 660nm light source is 100% efficient.

You can see the problem here. How would you measure 730nm and 400nm in lumens? 1W of 730nm radiation is practically invisible (0.355lm), but it's still 1W of radiation! A 0.355lm/W 730nm lamp would be a 100% efficient lamp!

Perhaps not totally fair, but easy.

Do you have general estimate of blurple to full spectrum phototropic efficiency?

For narrow band emitters, sometimes manufacturers list output in mW rather than lm. It's really nice when they do this, because then calculating efficiency is just a matter of putting the listed output over the input power, no bullshit LER calculations needed (which is sort of like mccree for humans).

The 730nm leds I got from LEDEngine didn't even list lumen output (i guess they figure it would make them seem weak).. only mW output. It made it very easy to calculate efficiency. mW out / mW in!

Calculate efficient. BS. Like I said, you don't have an education. Those spreadsheets are just BS to convince uneducated peoples to buy yet another Light. Sorry folks. Ain't drinking the kook aid. It's just another light. And all this spreadsheet crap is just a ploy to make uneducated pot heads think their smart when they shell out more dough for snake oil. lol.

Useless fodder to say the least.

Stop trying to pose like your a qualified EE. Your just a bunch of pot heads and thank Gawsh it's so easy to propagate weed because that means even you

@churchhaze @KarmaPaymentPlan

Can do it too. Along with everybody else in the world.

I seriously doubt many of you could pass even the most basic Electrical Tech classes.

awww!!! someones jealous!

why not talk bad about the 99% of commercial lights that aren't built as well...ya know...aluminum plates with no fins...sinks with a hole under the chip...bottom of the barrel drivers...$.10 leds......crappy fans....

ummm yea...you can shove your certificate where the sun don't shine


uneducated potheads huh....lol. watch out for karma..sounds like you know her well...:)

jealous of what? No. I'm trying to make sure the word is out so other noobs don't jump into this spreadsheet crap and waste money on yet another light simply because some pot heads are clever enough to read some spreadsheet crap, buy into it and sell it off like its some kind of miracle. It's just another choice in light to grow weed.

NO WONDER THE NOOBS ON TROLLITUP HAVE SO MANY ISSUES. THEY BUY INTO THIS CRAP SPEWED BY OTHER NOOBS.

Bottom line. You don't need an education to grow weed because it easy. That's why they call it weed. lol. People everywhere are doing it without the noob miracle lights.

And, why hasn't anyone shown a miracle plant under these? The only thing I've seen are decent plants grown under them. Comparable to decent grows with any of the other choices. Nothing special from what I've seen. Not drinking the noob kook aid. Nor should the noobs.

There are about 5 or 6 noobs who started a COB clique and pump the COB. It's just a light. Not impressed. Def don't wanna join this noob clique.

extraWOW!
:shock:



maybe you can tell us if some lights are better for this function than others?:idea:

Not even gonna waste my time looking at COB anymore. Reading all this pumped up crap and seeing average grows using it, I realize my Blurples are doing better than I even thought. That along with trying some top shelf from the dispensaries has me convinced that many of us amateur growers on the TROLLITUP are doing just as well quality wise as the commercial guys.
