I spoke with one of my fellows.
He recommended that I obtain two lots with three replicates per lot or an even wider number of lots for any given light type to spread the variability around and build confidence. I will work this part out.
I figure I would use an MVB as a well-accepted comparator. I am thinking the Exo Terra Solar Glo 160W. I would naturally obtain multiples.
For the coil type(s), I would use the Repti-Glo 2.0, 10.0, and/or 200 Intense. Maybe also the 5.0, but I would rather keep this to a maximum of three models in the class and brand. Preferably only two. I was thinking either the 2.0 and 10.0 or the 5.0 and 10.0 to keep this concise. I would like feedback on which two you would pick and a rationale as to why those two. I am leaning towards 5.0 and 10.0 and the reason why is because I think 1) these would be among the most commonly purchased, as they are the most commonly stocked in the chain stores, and 2) because their UV outputs might be more relevant to tortoise keeping (whether forest or savannah species) habits/usage.
The point of this is to determine a significant difference in the nature of outputs between the oft-maligned CFL-type UVB bulbs versus the oft-venerated MVB-type UVB bulbs with the MVBs serving mainly as comparative agents.
I was also going to consider burn-in time as a component with extended usage, but I realized that is not the point of what I am trying to determine. Loss of efficacy over the long term is not the crux of the discussion. As such, any time component will involve perhaps T=0, T=24hr, and maybe something like T=120hr.
Orientations will include at least parallel and perpendicular, but I may add something oblique because a number of folks/keepers may mount these via clamp lamps.
I will probably spread out the acquisition times and sources to try and avoid overlapping lots when I can, so procurement will be protracted.
I found one meter in storage and I have at least one at work. I will select which one I use based on calibration testing and potentially the specifications & capabilities for the units. I have three light boxes at work. I will probably choose the one which can be used to shield against incidental light best.
This will take some time (read: I will get to it when I get to it). Unless I am given a compelling reason, I will most likely stick with the 5.0 and 10.0 rationale I have given above.

I will eventually compose an actual protocol, too.
