forewarning: I have no f***ing clue on this one...
you may wanna try asking this in the gourmet/medicinal forum, theyhave a better idea on these types...

watts do not directly relate to lux, the bulbs vary.. i.e. metal halide - high pressure sodium, etc...

i think he is talking about a "grolux"tm. which is a wide spectrum florecent bulb made for aquariums .

Raadt is right about the conversions. Watts to lumens, lux etc will vary depending upon the light source used. Fluorescents tubes can give you between 90-110 lumens/Watt. Obviously since intensity of light varies in an inverse relationship with distance (actually inverse square) if you know the amount of lumens produced by your light source and the distance you can then figure out how intense the light will be hitting the surface of your cropping area.
If you have a full spectrum fluorescent grow bulb that nominally puts out 3000 lumens (normal distance for these types of measurements vary from the bulbs surface to one foot) at one foot, then you can calculate the amount of lumens the surface of your grow area is getting. I would think that a simple two bulb fluorescents at one foot from the caps should be more than enough. What shape of mushrooms you are interested in growing will also play a role. Long skinny ones or short fat ones. It should be noted that i am not very familiar with how lux compares to lumens per amount of area. good luck

No, I believe he is speaking of lumens, lux for short. The unit of luminous flux in the International System, equal to the amount of light given out through a solid angle by a source of one candela intensity radiating equally in all directions.

i stand corrected . the grolux i was speaking of is a 14" tube at 15 watts . but i probably would work .

realistically almost any bulbs will work, are you sure nameko is stimulated by blue spectrum? I know that cubensis is, i'm not sure if it applies to all fungi, though.
For cubes and pans, i used to use xmas lights... 2 strings of them in my terrariums.

thanks.. been a while since i look at light physics.

Stamets recomends sunlight or a grow light. I bought a 25watt grow-lux bulb for about $2US. It's designed for a terarium, but fits in a normal socket. I like it because it does not mess up my temps, and it only supplements natural light to get 12 hours of light per day.

yes, your calculations seem to be correct more or less.
what we really need to know here is why do you need to be so damned particular? what are you trying to do? the fact is, just about any old light bulb will work just fine, and you do not even need to have it on much. if you cant find a small enogh bulb, then use a dimmer to tone it down.
but in the size of your area, again you are getting into the area of cost control. you can buy those flamulinas at a grocery store around here for a lot less than a hundred bucks per pound, which is about what i suspect your production cost is or even higher.
is your issue that exposing the substrate to too much light is causing too much pinset, with resultant smaller more difficult to harvest fruits and too many aborts? before blaming this on the light, check ALL of your other pinset initiation factors and keep track of the overall ratio of surface area to volume, as well as depth and type of casing material if any.
if your production is not that sophisticated, then what you really need to know is that just about any damned light will work. don't spend a lot of money on it. I don't use any artificial light on my gormet mushrooms and it works just fine. any light you can read by at any distance will be sufficient to initiate pinset.

This wrong.. 1 lux is 1 lumen per square meter. A 10,000 lumen bulb lighting 2 square meters gives a light intensity of 5,000 lux.

Only if the entire surface is equidistant from light source. And assuming that the surface is at a distant where that nominal lumen output applies. (just being cheeky... procrastinating)
