I don't know. The caps seem to align themselves to minimize light hitting the stem. Perhaps because it's unpigmented and vulnerable to UV light.

cubensis in my experience always orients the cap like an umbrella to take most of the light it can. sometimes even the whole stalk will orient to the light as if to prevent light from hitting the stalk. you can grow spiral mushrooms if you rotate your substrate and have a strong light.

i have said a few times i think it will be surprisingly low 
I did it, i was using a fluorescent bulb right above of the tub. I got like 350-400 lux units at surface level (without the lid of the tub). When i put the lid on i got only 250 lux units. The plastic lid reduced the lux units by 100, and the lid was transparent clear plastic. So it doesn't matter how much transparent and clear your tub lids are.. they will significantly reduce the lux units.

this is inline with what i was thinking/saying at the start of the thread, that the fact is the way most use cfls the majority of light never reachs the surface of the substrate and that the levels would be comparable to a shady spot under vegetation outside.
glad you had a light meter and thanks very much for taking the time out to helping to clear that up 
EDIT even glass limits the amount of lux levels, thats why green house glass is special horticultural grade glass

Check the difference with angle. Instead of the light being directly above the tub, put it off to one side so it's coming down at an angle through the sides too. Change the distance as well. If you don't mind.

I'm no expert but from what i've read lux lumens only measures visible light. Par lumens are actual useable light. So brightness doesn't seem to be as important as once thought. It's the spectrum and the distance it can travel. Most of the light used by plants isn't seen by the human eye so it could be the same for mushrooms.

im a bit sad and but im enthralled by this thread. 
mr.alien i too like SBJ would love to know the outcome of them tests, its a wonder these have not been tested a thousand times already.

unless mush photosynthesize i dont see how Photosynthetically active radiation make a difference??? i could be wrong ,dont hold me too it

lower frequencies pass through solid objects easier than higher frequencies, too.
This isn't really a full scale analysis of whether or not your tubs are getting all the right light in the right quantities. But it is cool to know how much general affect distance and angles have on light passing through clear plastic.

I've only read the first and last pages, but has anyone done tests on this yet? I'm thinking about putting a mono under an HPS or LED to see if there's a difference with such a massive amount of light.

Maybe the canopy opens with too much intensity to protect the substrate from drying out . I nature very bright sun would mean the ground would dry up

Well i don't have any fruiting substrate going on now, but i can simulate sub depth with a pillow.
324 lux units, light directly from above no lid

277 lux units, light directly from above with lid on.

358 lux units with light source from a side of the tub as SBJ suggest. I did get more lux units this way and i assume is because the light source is closer to the substrate surface than from above or the plastic is thinner on the sides and the plastic is thicker on the lid.

The last time i did the measurements i got 100 lux units of difference with the light source from above with the lid and without it, but it was a tub with a thicker plastic i remember. This time i only got 47 lux units of difference with and without lid but again the plastic of this tub is thinner than the last time.
If you want to get the most lux units as possible. Try to choose the thinner clear plastic tub as possible. Cause i'm pretty sure the thickness of the plastic reduce lux units significantly. Or you can add more light sources.

Forgot about this one, it was also grown in the tub with no light

I've been wanting to experiment with some LEDs that I've ordered. I know mushrooms probably don't need the type of power photosynthesizing plants need from grow lights, so I'm curious to see if the standard 5mm LEDs would make a particular difference. If what you guys say is true, that the nonvisible spectrum of light is more important for growth I've got an awesome idea I could try out. Has anyone else done some research on this topic? I already know mushrooms prefer a day night cycle such as 12/12.

yes, from the side the light is closer so recieving more available lux/ lumens. what about angle of light penetrating the tub? will this reduce glare/ reflection and allow more penetration?
it would be interesting to see the light levels in a grass field, at ground level shaded by grass and also at cubensis fruit height just to see the differing range at different times of the life cycle.
maybe this is something we could replicate easily indoors if we had the figures and then would be able to gauge any benefits. this would dial the lighting in specific to wild cubensis conditions. after all there should be not be a blanket optimal amount of light for all mushrooms as they all grow in differing conditions i.e fields- deep forest shade.
