After analyzing the images. I have some findings to report:

The white reflector creates maximally ~11% brightness on our purple wall. And does this over 450 pixels(about 21x21 pixels). Pixel intensity: 27 and below.

The aluminum reflector creates maximally ~13% brightness. And decays to ~11% over an area of ~11,780 pixels. Pixel intensity: 33 to 27.

Or nearly 26 times increase in the pixels(area) with 11-13% brightness.

Without a reflector is maximally ~9% brightness. Pixel intensity: 22 and below.

The aluminum reflector has an area of around 22,000 pixels with over 9% brightness.

The white reflector has an area of around 7,600 pixels with over 9% brightness.

The aluminum reflector has around 290% increase of brightness per area.

Maximums:
Aluminum's 50% increase over nothing is governed by the 45 degree angle.
A 23% increase over nothing is gained with matte(specular overcoat) white and a 45 degree angle.
If I made the reflector parallel to the purple plane these would likely double(very close).

Think I could convince you to Simulate with LEDs?

Also have another question regarding another statement you made.

Is it the light that destroys the THC, or a component of the light, like UV Radiation, or IR Radiation, or some other radiation?

(Sorry, I know this is a noob-type question)

But are there any filters that could filter out UV or IR Radiation of that is actually what destroys the THC?

As far as I know, visible light will degrade it. As will IR and UV, quite likely. Probably from microwaves to gamma waves.

That sucks...

So what about simulating it with LEDs

Yeah, they have more expensive start up costs, but long term utility costs are a lot lower than CFLs, and the lifespans are a lot longer.

just found on ebay you can get luxeon stars 5 watt and over 100 lumens per watt. only 3000k colour and 6500k colour are that lumen output. they are now only 3 dollars. you may get a discount to if you buy bulk. They are simple to wire and can be placed densely together. also the lumen output is taken with the built in reflector so its more accurate. they also come in various beem angles i think. Personally i think these will blow away any of those purple or red led bulbs. I want to wire about 150 of those 3000k together. might try it. the price is right.

Sorry to bring this thread back to life, but there is something people need to understand about this.

As you guys can see it does not matter how many lumens your HPS or MH are putting out, because you are not absorbing the lumens. At 239 watts with fluoros on each side you would absorb the amount of light of the very highest end 750W MH you can find in production. Put one set of 4 bulbs on each side and you literally have 350W Veg side lighting, and then of course can put cfl's above, between or anything else.

So, everyone believes HPS/MH is far superior. Look at wattage, think of all the side lighting youve never gotten, you guys imagine what you could increase by at least trying to add fluoros or CFL's. They arent just supplemental. If someone were to run fluoros alone you could get the 8 X 4 Ft. HO T5 on the top, bottom and middle. This would equate to what the plant would see as 2,250Watts worth of the highest end MH Bulb by running 1,434W of fluoros @ far less heat than a 1000W MH would put out, and so there is even more savings on electricity. You also get perfectly even light, and total saturation.
