WHY do CFL's suck?

See this is the argument that I've also seen, but I've seen charts supposedly proving that light is "additive" meaning that if you were to put together 4 250w CFL's you would be able to produce 80,000 lumens and the fact that you could get them so close would offset the loss of 12,000 lumens. It seems to me like the real answer is that light IS NOT additive and just doesn't work that way.

Light is to some extent additive, but it doesn't seem to work in the practical application of CFL's. The intensity still diminishes far too quickly outside of the optimal distance.

If it were "truely" additive, this wouldn't be the case. The light would become "brighter" and therefore the degredation would be similar to an HID.

Maybe the answer lies in the right kind of reflector that can house multiple CFL's in a certain type of pattern. I don't really know, but I know that what we've got now doesn't work and doesn't appeart to be "additive" in the sense of growing marijuana with them.

So why do we use foot candles? Where 1 lumen/sq ft = 1 foot candle.

When two identical, in phase waves, interfere, they double in amplitude.

When 10 CFL's are put together, they don't penetrate any further than the original 2-4" efficiently. Why?

They do, actually. Just as adding a parabolic reflector would increase penetration. This is how flash lights work.

This is how LED flashlights work, multiple LEDs. This is how LED panels work. Multiple sources.

You're telling me one 1 watt LED is just as bright as a panel of 100 x 1 watt LEDs? You're not living in the same universe as I am, apparently.

you idiots arent thinking in terms of PAR.....lumens and par DO NOT ADD......period.




adding lights (of the same intensity) just spreads the luminous intensity more evenly...THATS IT. lumens will NEVER ADD, because the PAR value of the lightsource is the same.

why dont ONE of you tards go out and buy a lux meter and try it.....

Why don't you learn how to use a lux meter correctly? :roll:

Par is measured in micromoles/area/time. Overlapping light source add their micromoles, over the same area, in the same time.

What happens when you turn 1/x to 2/x. It doubles.

I'm experiencing the same thing, and I mean no one any disrespect in any of today's goings on (this isn't the only thread about this).

I really was looking to gain a better understanding of why it doesn't work, but TTO is too convinced it does to understand that the charts don't matter without results. You have to prove it DOES work before you can try to convince us about WHY it works.

parabolic reflector's are shit! they are the least efficient reflector. double parbolic are better with the bulb hung horizontally wich you can't do with a single parabolic reflector. there are far better reflectors than parabolic even the double parabolic.

at the time i had a book about the best reflector ( ill post links later) the best reflector on the market was this and that was over 10 years ago! things may even be a little better now?

[FONT=Verdana, Arial, Helvetica, sans-serif]UltraLite Pro Reflector

​
[FONT=Verdana, Arial, Helvetica, sans-serif]Award Winner - Most lumens from a 600w lamp![/FONT][FONT=Verdana, Arial, Helvetica, sans-serif]
[/FONT][FONT=Verdana, Arial, Helvetica, sans-serif]
[/FONT] The Power Plant Ultralite Pro is a high performance, light-weight reflector with patented design.​
Its eight-sided symmetrical design is made of high purity textured dimpled aluminium for maximum reflection and diffusion.​
The unit is ready assembled complete with lamp holder, supply lead with IEC plug and is supplies with full instructions for use.​
The lamp holder can be custom fitted for any size lamp ranging from 250 - 1000 watts.​
George van Patten's light test on reflectors from around the world (see Gardening Indoors with Lights, page 105), found the Pro-Ultralite gave the most lumens output from a 600w lamp for a 9sq meter area out of all reflectors tested.

The Hydrofarm Pro UltraLite offers top performance at an affordable price. Sold complete with reflector, ballast, bulb and socket. The UltraLite reflector weighs under 5 lbs. and is constructed of specular aluminum for maximum reflectivity. High Pressure Sodium (HPS) Lamps have initial lumens between 120,000-140,000 lumens and deteriorate slower than metal hallide lamps. They are dominant in the red-yellow spectrum and possess minimal amounts of the blue-green spectrum. The 600 watt HPS lamp has the best lumen-watt ratio, making it the most efficient to run. Up-grade your HPS lamp with a Hortilux lamp providing a ceramic instead of glass insulator, a longer contact end, ~5000 extra lumens, slightly enhanced blue-green spectrum, and an enhanced yellow spectrum

Seriously, this is basically addition, and it flies right over your head??

http://en.wikipedia.org/wiki/Lux

It is analogous to the radiometric unit watts per square metre, but with the power at each wavelength weighted according to the luminosity function, a standardized model of human brightness perception.

More watts, same sq meter, proportionally higher lux.

Take a mirror. Shine your room's light onto the wall. Look at the bright spot. PROVEN!

Take a flashlight, shine it on the wall. Look at bright spot. PROVEN!

Take a magnifying glass and burn yourself with it. PROVEN! :fire:

Use a reflector. Grow bigger plants. PROVEN!

I just proved it FOUR times, in four different ways.

You all are fucking ridiculous. You all are going on a rampage and trying to belittle this man because he does not have pictures. Everything he has said through out this thread is reputable.

I think it's funny how you all go on about how you want to see pictures and how fucking light is not additive? Are you fucking kidding me?

We have stuck information in your faces time after time yet everyone pulls kiddy bullshit. I guess this makes me crazy too...?

I can't wait to see what you label your damned selves. You must be something close to fucking retarded.

Not that I really feel like continuing this conversation anymore. My point is that light is additive, light isn't, flux, PAR, etc. why does HID STOMP CFL's in Grams/Watt?

Why can't TTO show us his grow where his Grams/Watt where fantastic?

That's how you motherfuckin' prove things you donks...anything else is theory, proof is in results.

PROOF PROOF PROOF, not theory or applied theory, or even application of information.

Fine, light is additive. It still doesn't grow MJ in comparison to HID, WHY NOT? Another wording of the same question and you have successfully taken over this thread AGAIN with rants about facts that you seem to know (whether they are true or not, and I don't really care) but none of them address the question of WHY DOESN'T THE APPLICATION OF THESE FACTS = BETTER RESULTS.

If you can't answer THESE questions, please TTO for the love of God, stay away from my thread.

Let's start with this, since I don't have adequate space or material to show you why your not getting the results you want, how about you show us ANY CFL grow you have done so we can crack at everything you have done wrong??
